SUMMARY
This report describes the Annual Radiological Environmental Monitoring Program (REMP) conducted near the Clinton Power Station (CPS) during the 1996 calendar year. The REMP was performed as required by the CPS Operating License issued by the United States Nuclear Regulatory Commission. The objective of the REMP is to assess any radiological impact upon the surrounding environment due to the operation of the Clinton Power Station. During 1996, over 1,700 environmental samples were collected. These samples represented direct radiation; atmospheric, terrestrial, and aquatic environments; and Clinton Lake surface water and public drinking water supplies. About 2300 analyses were performed on these environmental samples. Results of the analyses showed natural radioactivity and radioactivity attributed to other historical nuclear events. The radioactivity levels detected were similar to the preoperational levels. The CPS Preoperational REMP Report documented natural background radionuclides and man-made radioactivity in the environment surrounding CPS prior to plant operations. i Radiological environmental measurements taken during 1996 demonstrated that operational and engineered controls on the radioactive effluents released from the plant functioned as designed. Any radioactivity that was detected in the environment at indicator locations was appropriately compared with both the measurements at control locations (sample locations not affected by station operations) and preoperational results. Releases of gaseous and liquid radioactive materials were accurately measured in plant effluents. There were no effluent releases that came close to approaching the limits specified in the CPS Offsite Dose Calculation Manual (ODCM). The highest calculated offsite dose received by a member of the public due to the release of radioactive materials from Clinton Power Station was 0.00302 mrem. All comparisons among operational data and preoperational data showed that the operation of Clinton Power Station had no measurable effect upon the environmentin 1996. 1 L - - - - - - - - - - - _ _
II. INTRODUCTION The Radiological Environmental Monitoring Program (REMP) at Clinton Power Station (CPS) is designed to monitor the environment surrounding the plant for any radioactive material that may be released by CPS as a result ofplant operations. The primary concern is what impact, if any, the radioactive materials released from CPS have on the generalpublic. This report isprepared in a way that is useful to a specialized scientific community. However, this introduction, the explanations in later sections, and minimal use of technical terms are all designed to make this report understandable and useful to those with no background in environmental monitoring. A. CHARACTERISTICS OFRADIATION Atoms whose nuclei contain an excess of energy are called radioactive atoms. They release this excess energy by expelling electromagnetic or particulate radiation from their atomic centers to become stable (non-radioactive). This process is called " radioactive decay". X-rays and gamma rays are examples of electromagnetic to radiation and are similar in many ways visible light, microwaves and radio-waves. Particulate radiation may be either electrically charged such as alpha and beta particles, or has no charge, like neutrons. The term " half-life" refers to the time required for half of a given amount of a radionuclide to decay. Some radionuclides have a half-life as short as a fraction of a second, while others have a half-life as long as a million years. Radionuclides may decay directly into stable elements or may undergo a series of decays which ultimately end up reaching a stable element. Radionuclides are found in nature (e.g., radioactive uranium, thorium, carbon and potassium), and may also be 3
I produced artificially in accelerators and nuclear reactors (e . g . , radioactive iodine, cesium and cobalt). NATURALLY OCCURRING MAN-MADE I RADIONUCLIDES RADIONUCLIDES Uranium Iodine Thorium Cesium Chrbon Cobalt Potassium Strontium Lead Barium The activity of a radioactive source is the average I number of nuclear disintegrations (decay) of the source E per unit of time. The unit of activity is called the 3 curie. A one curie radioactive source undergoes 2.2 trillion disintegrations per minute, but in the realm of nuclear power plant effluents and environmental radioactivity, this is a large unit. Therefore, two f ractiortal units, the microcurie and the picocurie, are more commonly used. l l 1 curie (Ci) = 2,220,000,000,000 disintegrations / minute 1 millicurie (mci) = 2,220,000,000 disintegrations / minute 1 microcurie ( Ci) = 2,220,000 disintegrations / minute i 2,220 1 nanocurie (nCi) = disintegrations / minute 1 picoeurie (pCi) = 2.22 disintegrations / minute The microcurie (uci) is one millionth of a curie (Ci) and represents 2.2 E million decays per minute. The 5 picoeurie (pci) is one millionth of a microcurie and represents 2.2 decays per minute. Another way of comparing the pCi and the Ci is by analogy with distances. A picocurie would be the width of a pencil mark while a curie would be 100 trips around the earth. Radioactivity is related to the half-life and the atomic mass of a radionuclide. For example, Uranium-235 (U-235) with a half-life of 704 million years requires about 462,400 grams to obtain'an activity of one curie. E But iodine-131 (I-131) with a half-life of 8.04 days 3 j only requires about 0.000008 grams .to produce an activity of one curie. a g Any mechanism that can supply the energy necessary to ionize an atom, break a chemical bond, or alter the chemistry of a living cell are capable of producing biological damage. Electromagnetic and particulate radiation can produce cellular damage in any of these 4 I
ways. In assessing the biological effects of radiation, the type, energy, and amount of' radiation must be considered. External total body radiation involves exposure of all organs. Most background exposures are of this form. When radioactive elements enter the body through inhalation or ingestion, their distribution may not be uniform. + TARGET TISSUE NUCLIDE Bone Strontium-90 Kidney Uranium-235 Thyroid Iodine-131 Muscle and Liver Tissue Cesium-137 Gastrointestinal Tract Cobalt-60 For example, radiciodine selectively concentrates in the thyroid gland, whereas radiocesium collects in muscle and liver tissue, and radiostrontium collects in mineralized bone. The total dose to organs by a given radionuclide is also influenced by the quantity and the duration of time that the radionuclide remains in the body. Owing to radioactive decay and human metabolism factors, some radionuclides stay in the body for very short times while others remain for years. The amount of radiation dose that an individual receives is expressed in rem. Since human exposure to radiation usually involves very small exposures, the millirem (mrem) is the unit most commonly used. One millirem is one thousandth of a rem. 1 millirem = 0.001 Rem B. SOURCES OFRADIATION EXPOSURE Many sources of radiation exposure exist. The most common and least controllable source is natural background radiation from cosmic rays and the earth which mankind has always lived with and always will. Every second of our lives, over seven thousand atoms undergo radioactive decay in the body of the average adult. 5 w - _ _ _ .
I Radioactive elements have always been a part of our I planet and everything that has come from the earth, including our own bodies is, therefore, naturally radioactive. Natural Radionuclides In The Earth's Crust I Potassium-40 (K-40) Radium-226 (Ra-226) I Uranium-238 (U-238) Radon-222 (Rn-222) g Thorium-232 (Th-232) Lead-204 (Pb-204) g Examples of radioactive materials found in the Earth's crust today consists of radionuclides such as potassium-so, uranium-238, thorium-232, radium-226 and radon-222. These radionuclides are introduced into the water, soil and air by such natural processes as volcanic activity, g weathering, erosion and radioactive decay. 3 Some of the naturally occurring radionuclides, such as radon, are a significant source'of radiation exposure to a the general public. Radioactive radon is a chemically g inert gas produced naturally in the ground as a part of the uranium and thorium decay series. Radon continues E tu undergo radioactive decay, producing new naturally W radioactive materials called " radon daughters". These new materials, which are solid particles, not gases, can stick to surfaces such as dust particles in the air. Concentrations of radon in air are variable and are affected by concentrations of uranium and thorium in soil, as well as, altitude, soil porosity, temperature, i pressure, soil moisture, rainfall, snow cover, atmospheric conditions, and season. Radon can move through cracks and openings into basements o. buildings $ and become trapped in a small air volume indoors. 5 Thus, indoor radon concentrations are usually higher than those found outdoors. Building materials such as cinder a blocks and concrete are radon sources. Radon can also g be dissolved in well water and contribute to airborne radon in houses when released through showers or washing. Dust containing radon daughter particles can be inhaled 3 and deposited on the surface of an individual's lung. E Radon daughters emit high energy alpha radiation dose to the lung lining. Table 1 shows the average annual effective dose due to radon. About three hundred cosmic rays originating from outer space pass through each person every second. e I
Cosmic-Ray-Activated Radionuclides Beryllium-7 (Be-7) Tritium (H-3) Beryllium-10 (Be-10) Sodium-22 (Na-22) Carbon-14 (C-14) Phosphorus-32 (P-32) The interaction of cosmic rays with atoms in the earth's atmosphere produces radionuclides such as Beryllium-7, Beryllium-10, Carbon-14, tritium, and Sodium-22. Portions of these radionuclides become deposited on land or in water while the remainder stay suspended in the atmosphere. Consequently, there are natural radioactive materials in the soil, water, air and building materials that contribute to radiation doses to the human body. Natural drinking water contains trace amounts of uranium and radium; milk contains measurable amounts of potassium-40. Sources of natural radiation and their average contributing radiation doses are summarized in Table 1. Figure 1 graphically shows the percentage contribution from principal sources of radiation exposure to the general population of the United States. Radiation exposure levels from natural. radiation fluctuate with time and also can vary widely from location to location. The average individual in the United States receives approximately three hundred mrem per year from natural sources. In some areas of the country, the dose from natural radiation is significantly higher. Residents of Colorado, five thousand feet above sea level, receive j additional dose due to the increase in cosmic and terrestrial radiation levels. In fact, for every one thousand feet in elevation above sea level, an individual will receive an additional one mrem 'per year from cosmic radiation. In several areas of the world, high concentrations of mineral deposits result in natural background radiation levels of several thousand mrem per year. l In addition to natural background radiation, the average individual is exposed to radiation from a number of man-made sources. The largest of these sources come from medical diagnosis: X-rays, CAT-scans, fluoroscopic examinations and radio-pharmaceuticals. Approximately 160 million people in the United States are exposed to medical or dental X-rays in any given year. The annual dose to an individual from such irradiation averages 53 mrem. 7 l.... . . .

I C. DESCRIPTION OF THE CLINTON POWER STATION The Clinton Power Station is located in Harp Township, DeWitt County, Illinois. It is approximately six miles east of Clinton, Illinois. The station, its V-shaped cooling lake, and the surrounding Illinois Power Company-owned land encloses 14,182 acres. This includes the 4,895-acre, man-made cooling lake and about 90 acres of privately owned property. The plant is sited on approximately 150 acres on the northern arm of the lake. The cooling water discharge flume, which discharges to the eastern arm of the lake, occupies an additional 130 acres. Although the nuclear reactor, supporting equipment, and associated electrical generation and distribution equipment lie in Harp Township, portions of the 14,182 acres lie in Wilson, Rutledge, DeWitt, Creek; Nixon and Santa Anna Townships. ~ The cooling lake was formed by constructing an earthen dam near the confluence of Salt Creek and the North Fork I of Salt Creek. The resulting lake has an average depth of 15.6 feet, and includes an ultimate heat sink of E 5 about 590 acre-feet. The ultimate heat sink provides sufficient water volume and cooling capacity for approximately thirty days of operation without makeup water. Through arrangements with the Illinois Department of Conservation, Clinton Lake and much of the area immediately adjacent to the lake are used for public recreation activities, water-skiing, hunting including and swimming, fishing. boating, Recreational g 3 facilities exist at Clinton Lake and accommodate up to 11,460 people per day during peak usage periods. The outflow from Clinton Lake falls into Salt Creek and flows in a westerly direction for about 56 miles before joining the Sangamon River. The Sangamon River. drains into the Illinois River which enters the Mississippi River near Grafton, Illinois. The nearest use of downstream water for drinking purposes is 242 river miles downstream of Clinton Lake at Alton, Illinois, as verified from the Illinois Environmental Protection Agency Public Water Service. Although some farms in the Salt Creek drainage area downstream of Clinton Lake use irrigation, the irrigation water is drawn from wells, not from the waters of Salt Creek. Approximately 810,000 individuals live within 50 miles of the Clinton Power Station. Over half are located in g the major metropolitan centers of Bloomington-Normal a (located about 23 miles north northwest), Champaign- g Urbana (located about 31 miles east), Decatur (located g 12
about 22 miles south southwest) and Springfield (located about 48 miles west southwest). The nearest city is Clinton, the county seat of DeWitt County. The estimated population of Clinton is about 8,000 people. Outside of the urban areas, most of the. land within 50 miles of the Clinton Power Station is used for farming. The principal crops grown are corn and soybeans. D. NUCLEAR REACTOR OPERATIONS. The fuel of a nuclear reactor is made of the element uranium in the form of uranium oxide. The fuel produces power by the process called " fission". In fission, the uranium atom absorbs a neutron and splits to produce fission products, heat, radiation and free neutrons. The free neutrons travel in the reactor core and further absorption of neutrons by uranium permits the fission process to continue. As the fission process continues, more fission products, radiation, heat and neutrons are produced and a sustained reaction occurs. The heat produced is extracted from the fuel to produce steam that drives a turbine generator to produce electricity. The fission _ products are predominantly radioactive. They are unstable elements that emit radiation as they change from unstable to stable elements. Neutrons that are not absorbed by the uranium fuel may be absorbed by stable atoms in the materials that make up the components and structures of the reactor. In such cases, stable atoms often become radioactive. This process is called " activation" and the radioactive atoms which result are called " activation products". Fission Products Activation Products Cesium-134 (Cs-134) Cobalt-60 (Co-60) i Cesium-137 (Cs-137) Manganese-54 (Mn-54) l Ruthenium-106 (Ru-106) Iron-55 (Fe-55) ' Barium-140 (Ba-140) Iron-59 (Fe-59) Cerium-144 (Ce-144) Zinc-65 (Zn-65) l Strontium-89 (Sr-90) Tritium (H-3) l l The reactor at the Clinton Power Station is a boiling ' water reactor (BWR). Figure 2 provides a basic plant schematic for the Clinton Power Station and shows the separation of the cooling water from plant systems. In this type of reactor the fuel is formed into small ceramic pellets that are loaded into sealed fuel rods. 13

The fuel rods are arranged in arrays called bundles that are supported within a massive steel reactor vessel. The spaces between the fuel rods are filled with water. The heat released during the fission of fuel atoms is transferred to the water surrounding the fuel rods. A type of pump that contains no moving parts (a jet pump), and recirculation pumps are used to force the water to circulate through the fuel bundles to assure even cooling of the fuel rods. As the water absorbs heat from the fuel rods some of it is changed to' steam. The steam is used to drive a turbine which is coupled to a generator, thereby completing the conversion of the energy released during fission to electricity. After the steam passes through the turbine it is condensed back to water and returned to the reactor vessel to repeat the process. As the water circulates through the reactor pressure vessel, corrosi6n allows trace quantities of the component and structure surfaces to get into the water. The corroded material also contains radioactive substances known as activated corrosion products. Radioactive fission and activation products are normally confined to the primary system although small leaks from the primary system may occur. E. CONTAINMENT OFRADIOACTIVITY
,During operating conditions, essentially all radioactivity is contained within the first of several barriers that collectively prevent escape of radioactivity to the environment.
The fuel cladding (metal tubes) provides the first barrier. The ceramic fuel pellets are sealed within zircaloy metal tubes. There is a small gap between the fuel and the cladding where the noble gases and. volatile nuclides collect. The reactor pressure vessel and the steel piping of the primary coolant system provide the second barrier. The reactor pressure vessel is a seventy-foot high vessel with steel walls ranging from four to seven inches thick which encase the reactor core. The reactor pressure vessel and the steel piping provide containment for all radionuclides in the primary coolant. The Containment Building provides the third barrier. The Containment Building has steel-lined, four-foot-thick reinforced concrete walls which completely enclose the reactor pressure vessel and vital auxiliary equipment. This structure provides a third line of 17 t
I defense against the uncontrolled release of radioactive materials to the environment. The massive concrete walls also serve to absorb much of the radiation emitted during reactor operation or from radioactive materials created during reactor operations. F. SOURCES OFRADIOACTIVE EFFLUENTS In an operating nuclear power plant; most of the fission products are retained within the fuel and fuel cladding. However, the fuel manufacturing process leaves traces of uranium on the exterior of the fuel tubes. Fission products from the eventual fission of these traces may be released to the primary coolant. Other small amounts of radioactive fission products are able to diffuse or migrate through the fuel cladding and into the primary coolant. Trace quantities of the corrosion products from component and structural surfaces that have been activated, also get into the primary coolant. Many soluble fission and activation products such as radioactive iodines, strontiums, cobalts and cesiums are removed by demineralizers in the water purification systems. The noble gas fission products, activated atmospheric gases introduced with reactor feedwater, and some of the volatile fission products such as iodine and bromine, are carried from the reactor pressure. vessel to the condenser with the steam. The steam jet air ejectors or the condenser vacuum pump remove the. gases from the condenser and transfer them to the off-gas treatment system. In the off-gas treatment system, the gases are held up by adsorption on specially treated charcoal beds to allow radioactive gases to decay before they are released through the main ventilation exhaust stack. i Small releases of radioactive liquids from valves, l piping, or equipment associated with the primary coolant ; system may occur in the Containment, Auxiliary, Turbine, RadWaste and Fuel Buildings. The noble gases become ! part of the gaseous wastes while the remaining g radioactive liquids are collected in sumps and processed 3ll for reuse. Processed primary coolant water that does not meet chemical specifications for reuse may also become .aste water. These represent the principal ) sources of liquid effluents. > 1 Il I
- g
G. RADIOACTIVE WASTE PROCESSING In a normal operating nuclear power plant, radioactive liquid and gaseous wastes are collected, stored and processed through treatment systems to remove or reduce most of the radioactivity (excluding tritium) prior to reuse within the plant or discharge to the environment. These processing systems are required by the Clinton Power Station Offsite Dose Calculation Manual to be installed and operable to help ensure all releases of radioactive liquid and gaseous effluents are As Low As Reasonably Achievable (ALARA). The liquid waste treatment systems consist of filters, demineralizers and evaporators. Liquid wastes are routed through the waste evaporators to be degassed and distilled thereby reducing their volume and concentrating their radioactivity. The distillates are further treated through demineralizers and filters and transferred to the waste evaporator condensate storage tanks. Liquid wastes are processed through the appropriate portions of the liquid waste treatment system to provide assurance that the releases of radioactive materials in liquid effluents will be kept ALARA. Liquid wastes are discharged into the plant cooling water stream which varies from approximately 5,000 gallons per minute, when the plant is in shutdown, to 567,000 gallons per minute, when the plant . is at ' full power. The liquid effluents are thoroughly mixed with and diluted by the plant cooling water as it travels the 3.4 miles of the discharge canal before it enters Clinton Lake east of DeWitt County Road 14. The Clinton Power Station Offsite Dose Calculation Manual requires that liquid effluents not contain a higher concentration of any radioisotope than that which is set for continuous exposure to the general. public. This condition is satisfied at the point the liquid effluent is first introduced into the cooling water flow. The additional dilution that occurs in the cooling water canal reduces the concentrations of radioisotopes to between 1/73 (for minimum flow) and 1/1890 (for maximum flow) of their original value before the water enters Clinton Lake. The concentrated radioactive solids captured in the liquid waste treatment system are processed and stored on-site or shipped off-site for disposal at licensed j low-level waste disposal facilities. The gaseous effluents from the main condenser are held up in the off-gas charcoal beds for at least 46 hours. 19
I This provides time for the decay of most of the radionuclides present since most have a half-life of less than 8 hours. If gaseous effluents in the ventilation exhaust system for the Containment Building and for the Secondary Containment structure exceed conservatively set levels, they are processed through charcoal beds and high efficiency particulate air g g filters in the Standby Gas Treatment System before being discharged to the environment. This combination of filters and charcoal beds is rated to be 95% efficient for removing iodines and greater than 99% efficient for removing particulate material larger than one micron (one millionth of an inch) in diameter.

III. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. PROGRAM DESCRIPTION The Clinton Power Station is required to maintain a radiological environmental monitoring program in accordance with the Code of Federal Regulations (CFR) Title 10, Section 20.1501 and Criterion 64 of CFR Title 10, Part 50, Appendix A. The program was developed using the following guidance published by the United States Nuclear Regulatory Commission (USNRC) :
- o Regulatory Guide 4.1, " Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants"
- o USNRC Radiological Assessment Branch Technical Position on Radiological Environmental Monitoring (1979)
The Radiological Environmental Monitoring Program is an extensive program of sampling, measuring and analyzing that was instituted to monitor the radiological impact of reactor operation on the environment. objectives of the program include: 0 identification, measurement and evaluation of existing radionuclides in the environs of the Clinton Power Station and fluctuations in radioactivity levels which may occur 0 evaluation of the measurements to determine the impact of Clinton Power Station operations on the local radiation environment 0 collection of data needed to refine environmental radiation transport models used in offsite dose calculations 0 verification that radioactive material containment systems are functioning to minimize environmental releases to levels that are ALARA 0 demonstration of compliance with regulations and the Clinton Power Station Offsite Dose Calculation Manual. Implicit in these objectives are the requirements to trend and assess radiation exposure rates and radioactivity concentrations in the environment that may contribute to radiation exposure to the public. The program consists of two phases, preoperational (preop) and operational. 1 I 21
I The preoperational portion of' the program was initiated in I May, 1980 and was completed on February 27, 1987 to establish the baseline for the local radiation environment. Assessment of the operational impact of the l Clinton Power Station on the radiation environment is g based on data collected since the beginning of reactor g operation. The operational phase implements confirmatory measurements to verify that the in-station controls for the release of radioactive material are functioning as designed. Illinois Power Company maintains a contract with Teledyne E Isotopes Midwest Laboratory (TIML) dba Teledyne Engineering Environmental Brown E Services Midwest Laboratory (TBEESML), for analysis of all radiological environmental g samples. TIML is located in Northbrook, Samples are collected by Illinois Power Company personnel Illinois. g and shipped to TIML for analysis. After ana' lysis, environmental samples are saved at TIML for a specified period of time in case additional analysis is required. Analytical results are reported monthly to company radiation protection personnel. Current regulatory guidance recommends evaluating direct pathways, or the highest trophic level in a dietary pathway, that contribute to an individual's dose. a 3 shows the basic pathways of gaseous and liquid Figure g radioactive effluents to an individual. The "important pathways" selected are based primarily on how radionuclides move through the environment and eventually expose individuals, as well as man's use of the environment. The scope of the program includes the monitoring of five environmental compartments: direct rc.diation atmospheric aquatic terrestrial environments ground and surface water. Each pathway is monitored at " indicator" and " control" locations. Indicator locations are generally within the 10-mile radius of the station. Control locations are located at least ten miles from the plant, far enough to be unaffected by plant operations. An increase in dose rate or radioactive material concentration at an indicator location may be due to plant operations. I I n g

l B. Direct Radiation Monitoring Radionuclides present in the air, and those deposited in or on the' ground cause human exposure by immersion in the atmosphere or by deposition on the . ground. j TLDs (thermoluminescent dosimeters) are used to measure the ) ambient gamma radiation field at many locations around the Clinton Power Station. TLDs are crystalline devices that store energy when they are exposed to radiation. They can be processed months after exposure with minimal loss of information. This makes them well suited for quarterly environmental radiation measurements. During processing, - the stored energy is released - as light and measured by a TLD reader. The light intensity is. proportional to the radiation dose the TLD received. The TLDs used-in monitoring around the Clinton Power Station are easily capable of measuring environmental levels of ! radiation, approximately 20' mrem per quarter. Monitoring stations are placed near the site boundary and approximately five miles from the reactor, in locations i representing the sixteen compass sectors. Other locations are chosen to measure the radiation field at places of special interest such as nearby residences, _ meeting places and population centers. Control site, sites are located further than ten miles from the in areas that should not be affected by plant operations. TLD measurements register _the gamma ray exposure in milliroentgen (mR). For reporting purposes mR is numerically equivalent to mrem. Consequently the terms are used interchangeably. A total of 344 TLD measurements were made in' 1995. The average quarterly dose at indicator locations was 17.6 mrem. These quarterly measurements ranged from 11.8 to 22.2 mrem. At control locations the average quarterly dose was 18.1 mrem. These quarterly control measurements ranged from 14.0 to 21.0 mrem. Figure B compares the 1996 quarterly TLD results with preoperational TLD quarterly averages. Average doses ( 2 standard deviations), broken down by-calendar quarter, are shown in Table 4 for both indicator l and control locations. l 43

I C. Atmosoheric Monitorino l i The inhalation and ingestion of radionuclides in the air ! is a direct exposure pathway to man. A network of ten j active air samplers around the Clinton Power Station ! monitors this pathway. There are nine indicator air ] sampling stations strategically located in areas which are 1 most likely to indicate effects due to the release of radioactive effluents from the Clinton Power S.tation. The l control location is located approximately 16 miles south ; of the plant in an area which is likely to be independent of the effects of station operations. Historical meteorological data indicates this control location is normally upwind from the plant. No contribution to the general level of airborne particulate radioactivity could be identified as a result l of station operations. The radioactivity that was ! detected is normally found in the environment and is l consistent with expected concentrations of natural radioactivity and fallout from prior atmospheric nuclear weapons testing. 47
I Mechanical air samplers are used to draw a continuous volume of air through a filter and charcoal cartridge to collect particulates and radiciodines present in the atmosphere. The samplers are equipped with a pressure-sensing flow regulator to maintain a constant sampling flow rate of about one cubic foot per minute. The total volume is calculated based on the amount of time the air sampler ran and its flow rate. The air sampling equipment is maintained and calibrated by the Clinton Power Station personnel using reference standards traceable to the National Institute of Standards and Technology. Air samples are collected weekly and analyzed for gross l beta and I-131 activities. Quarterly, all air particulate a filters collected during that period are combined and counted for gamma isotopic activity. Since the intent of particulate sampling is to measure airborne radioactivity released from the plant, the counting of short-lived daughters produced by the decay of natural radon and thoron may mask plant contributions. Therefore, the filters are not analyzed for at least five days after their collection to allow for the decay of the short-lived daughters, thereby reducing their contribution to gross beta activity. Results of the gross beta airborne particulate analyses provided comparisons between indicator and control locations for the year, as well as comparisons between locations in relation to spatial and temporal differences. The calculated annual average was 0.020 pci/m3 for all indicator locations and 0.021 pCi/m3 for the control location. These results are consistent with the preoperational averages for both indicator and control g locations which were 0.027 pCi/m3, g, The location with the highest calculated annual average was the control station CL-11 which is located 16 miles south of the Clinton Power Station. This location had an average concentration of 0.021 pCi/m3 Individual location averages for the year are presented in Table S. Minor fluctuations in the gross beta concentrations were ! noted throughout the year. The general trend for average l weekly gross beta concentrations in the indicator i locations correlated to the trend for control locations l throughout the monitoring period. This correlation is evidenced by the similarity of the trends in the average monthly gross beta concentrations displayed in Figure 9. No significant difference was indicated between individual locations. Monthly averages for indicator and control locations for the year are presented in Table 6. I L

D. Acuatic Monitorina The Clinton Power Station utilizes a man-made lake as the source of cooling water and returns the used cooling water to the same lake while most nuclear power stations use once-through flow from a river, the ocean or a body of water much larger than Clinton Lake. When radioactive liquid effluents are discharged from the Clinton Power Station into the cooling water outfall, radioisotopes with long half-lives could build up as the same water is reused on successive trips through the plant. This water travels from the plant, into the eastern arm of the lake, then into the northern arm of the lake and back into the plant. Although the only user of Clinton Lake as a source of drinking water is the Clinton Power Station, the lake is a major recreational facility, used for fishing, swimming, water skiing, boating and hunting. Clinton Lake exposure pathway for radioactive materialsenvironmental constitutes the primary in liquid effluents. Aquatic monitoring provides for the collection of fish, shoreline and bottom sediments, and periphyton samples to detect the presence of any radioisotopes related to operation of the Clinton Power Station. These samples are analyzed for naturally occurring and man-made radioactive materials. Both indicator and control locations were sampled. Indicator samples were taken from various locations on Clinton Lake and the control samples were taken at Lake Shelbyville which is approximately 50 miles south of Clinton Power Station. Aquatic monitoring samples are collected by personnel from the Field Biology Laboratory of the Environmental Resources Department of Illinois Power Company. Fish Samples of fish are collected from Clinton Lake and Lake Shelbyville. In both lakes the samples include largemouth bass, crappie, carp and bluegill. These species are the fish most commonly harvested from the lakes by sport fishermen. Fish ingest sediments during bottom feeding, or prey on other organisms which ingest sediments or otherwise retain radionuclides. Radiological analyses of these ingestion fish samples provide information on the potential of radionuclides by humans via the aquatic pathway. These samples are collected semiannually and analyzed by gamma spectroscopy. The results of gamma isotopic analysis on the fish samples showed samples the presence of naturally occurring K-40 in all ranging from 1.86 to 3.34 pCi/g (wet). Preoperational K-40 concentrations ranged from 1.71 to 4.61 pCi/g (wet) All other analytical results were less 53
I than the lower limit of detection (LLD) for, each I radionuclide. Shoreline Sediments Samples of shoreline sediments are collected at six locations from Clinton Lake and at one location from Lake Shelbyville. Radiological analyses of shoreline sediments provide humans information on the potential shoreline exposure to g and for determining long-term trends and accumulation of long-lived 5 radionuclides in the environment. Samples are collected semiannually and analyzed for gross beta, gross alpha, Sr-90 and gamma g isotopic netivities. g Shoreline sediment samples are dried prior to analysis and the results are reported in pCi/g dry weight. Naturally occurring were radioisotopes, present such as K-40, Ra-226 and P,b-212, in samples taken at both indicator and control locations. There were two fission products, Cs- g 137 and Sr-90, detected at two indicator locations. 3 The activity detected was not substantially different from that measured during the preoperational program. The presence of these fission products is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at chernobyl.

This activity was attributed to naturally W occurring radioisotopes and decay products present in soil. This value compare closely with the activity a detected in the preoperational program which ranged from g l 3.8 to 8.O pCi/g (dry). l Gross beta activity in samples of shoreline sediments 5 collected from all locations ranged from 5.56 to 13.00 pCi/g (dry). The majority of this activity was attributed g to naturally occurring K-40. These values are comparable with the gross beta activity detected in 3 the preoperational (dry). program which ranged from 7.0 to 17.2 pCi/g I e4 3

Samples of bottom sediments are collected - from Clinton !' Lake at six locations and Lake Shelbyville at' one location. Radiological analyses of bottom sediments ! primarily provide information about the amount of ; radionuclides available to predators who feed on the l organisms found in bottom sediments. Samples are collected semiannually and analyzed for gross beta, gross i alpha, Sr-90 and gamma isotopic activities. Bottom sediment samples are dried prior to analysis and the results are reported in pCi/g dry weight. Naturally occurring radioisotopes, such as K-40 and Pb-212, were present in all control and indicator sample locations. ' and Cs-137 Sr-90 was detected in samples from both ; indicator and control locations. Both radioisotopes are ' fission products. .

I radionuclides directly from w a t.e r , often concentrating them to levels much higher than the dilute concentrations that occur in the aquatic environment. This is because most algae are coated with a carbohydrate jelly and have a large surface-to-volume ratio. Cell division usually occurs once every one or two days and, as a result, half of the cell wall is a new g surface for sorption. 3 Periphyton represent one of the earliest links in the food chain and provide information about the amounts of radionuclides available to predators further up the food chain. Samples of periphyton are collected every two months between April and October (during the colder months growth is limited) at the indicator locations and semiannually at the control location and analyzed by gamma spectroscopy. Periphyton analyses are included in the Clinton Power Station Environmental Monitoring Program because of'their sensitivity to the presence of radionuclides in the aquatic environment due to bio-magnification. Using periphyton as biomonitors for radionuclides in aquatic systems can be a E highly sensitive and W qualitatively around effective means of environmental monitoring nuclear power plants that release radioactive effluents to aquatic systems. It enables the Radiological Environmental Monitoring Program to determine the relative presence of radioactivity before it becomes a problem. The results of the gamma isotopic analyses on periphyton samples showed the following concentrations of naturally occurring radioisotopes: Preop Range 1995 Range 1996 Range (oci/a drv) (DCi/o drv) (oCi/a drv) Be-7 0.38 - 1.07 0.39 - 2.27 0.49 - 1.93 K-40 0.74 - 6.82 0.60 - 5.46 1.39 - 5.51 One fission product, Cs-137, was detected in several I periphyton samples. Concentrations for Cs-137 ranged from 0.024 to 0.086 pCi/g (wet). Preoperational results for Cs-137 showed concentrations ranging from 0.042 to 0.15 pCi/g (wet). The presence of Cs-137 is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at Chernobyl. I l I 56
E. Terrestrial Monitorina In addition to the. direct radiation, radionuclides present in the atmosphere expose individuals when deposited on-surfaces (e.g., plants and soil) and are subsequently ingested directly by man or indirectly by consumption of animal products (e.g., meat and milk) . To monitor this food pathway, samples of green leafy vegetables, grass, milk and meat are analyzed. - Surface soil samples are collected and analyzed annually at the sewage sludge application site to ensure radionuclides attributed to the operation of Clinton Power Station are not being land applied with the processed sewage sludge. Every three years, samples are taken at nine other locations to monitor the potential buildup of atmospherically deposited radionuclides. Surface vegetation samples are collected from'a number of locations for the purpose of monitoring the potential buildup of atmospherically deposited radionuclides. Because the radionuclides of interest, with respect to the Clinton Power Station operations, are also present in the environment as a result of several decades of worldwide fallout or because they are naturally occurring, the presence of these radionuclides is expected in all of the samples collected. The possible contributions of radionuclides from the operation of the Clinton Power Station are assessed by comparing the results of samples collected in prevalent downwind locations (north to north north-east of the plant) with control samples and samples collected in locations generally upwind of the plant. In addition, the results of samples collected during the year were compared with the results of samples collected during the preoperational program. In addition to naturally occurring radioisotopes, Sr-90 was found in several samples. However, the concentrations of radionuclides in samples collected near the Clinton Power Station were comparable to the concentrations in samples collected at locations remote from the station. The presence of this fission product is attributable to previous nuclear weapons testing and fallout from the accident at Chernobyl. The operation of Clinton Power Station had no measurable contribution to the radioactive concentration of the terrestrial environment. Milk There is no known commercial production of milk for human consumption within a five-mile radius of the Clinton Power Station. Milk samples are collected from a dairy located 57
I about 14 miles west southwest of the station and goat milk is collected from a family residence 3.5 miles south southwest of the station (twice a month during May through October and once a month during November through April) . These samples are analyzed for I-131, Sr-90 and gamma isotopic activities. Results of the analyses showed positive concentrations of K-40 and Sr-90 ranging from 1310 to 2220 pCi/l for K-40 and 0.8 to 3.8 pCi/l for Sr-90. Precperational activity of K-40 in milk ranged from 706 to 1375 pCi/1. Strontium-90 analysis in milk was added to the REMP during the operational phase of the program, therefore there were no preoperational data for this isotope. I-131 was not detected in any of the milk samples collected. Figure 10 presents the Sr-90 results graphically. Grass In addition to milk samples, grass samples are collected at three indicator locations and at two control locations. These samples are collected twice a month during May through October and once a month during November through E April (when available). Grass samples are analyzed for 5 gamma isotopic activity including I-131. The results of the analyses showed only naturally occurring Be-7 and K-40 in these samples. Iodine-131 was l not detected in any of the grass samples collected.

The indicator locations are located in the l sectors with the highest potential for surface deposition i and the control location is in a sector and at a distance l which is considered to be unaffected by plant operations. Samples are collected once a month during the growing season (June through September) and analyzed for gross beta and gamma isotopic activities including I-131. ' I , I;

Meat As an additional check on the presence of radioactive materials in terrestrial exposure pathways, adnual samples of beef liver, beef thyroid and edible beef portions are collected from an animal raised near the Clinton Power Station. These samples are analyzed for gamma isotopic activity including I-131. The results of the gamma isotopic analysis showed only naturally occurring K-40 in the liver and the edible beef portions at 2.20 and 2.48 pCi/g (wet) respectively. Preoperational activity ranged from 1.95- to 2.78 pCi/g (wet). I-131 was not detected in the meat samples collected. Soil one soil sample was collected from an area where Clinton Power Station land applies processed sewage sludge from the Clinton Power Station Sewage Treatment Plant. Soil samples are sifted to remove any stones or debris, then dried and analyzed. All soil samples are analyzed for gross beta, gross alpha and gamma isotopic activities. Gross beta activity was 19.90 pCi/g (dry). Gross alpha activity was 7.95 pCi/g (dry). Gamma isotopic activity indicated several naturally occurring isotopes, such as K-40, Bi-214 and Pb-212. l 61
I F. Water Monitorino Water monitoring provides for the collection of drinking water, surface water and ground water (well water) samples to detect the presence of any radioisotopes related to the operation of the Clinton Power Station. The only identified user of water from Clinton Lake for domestic purposes is the Clinton Power Station; all others potentially exposed to any radioisotopes released into surface or ground water would not be affected for several years. Samples taken were analyzed for naturally occurring and man-made radioactive isotopes. Average gross beta concentrations in surface, drinking and well water are presented in Table 7 at the end of this section. 3 3 Drinkino Water A composite water sampler located in the Service Building collects a small, fixed volume sample at hourly intervals. The sampler discharges each sample into a common sample collection bottle. Therefore, the monthly sample analyzed by the contracted laboratory service is a composite of the individual samples collected throughout the month. The monthly composite sample is analyzed for gross alpha, gross beta and gamma isotopic activities. A portion of 1 each monthly sample is mixed with the other monthly l samples collected during each calendar quarter. The ; quarterly composite sample is analyzed for tritium. ' 1 Gross beta activity ranged from 1.9 to 2.8 pCi/1. These levels are attributed to very fine particles of sediment containing K-40 which are not removed during the l chlorinating and filtration process. Monthly drinking water 11. gross beta concentrations are presented in Figure Gross alpha activity ranged from 0.6 to 0.7 pCi/1. Preoperational result were all below the lower limits of E E detection except for one result which was 0.4 pCi/1. These levels can be attributed to naturally occurring radioisotopes, such as U-238 and Ra-226, suspended as fine sediment particles in water. The results of all analyses for tritium and gamma-emitting radioisotopes were all less than the lower limit of detection. These results show no measurable effects on drinking water resulting from operation of the Clinton Power Station. l I 62

i Surface Water Composite water camplers are installed in three locations to sample surface water from Clinton Lake. These samplers collect a small volume of water at regular intervals and discharge it to a large sample collection bottle. These bottles are collecced monthly. i Two of the composite samplers are located upstream from Clinton Power Station and are uhaffected by plant liquid releases downstream. The other composite sampler is positioned to sample the water released from the plant at the start of the plant discharge flume. Monthly grab samples are collected from two indicator locations and one control location on Clinton Lake. l Surface water samples are analyzed for gross beta, gamma j isotopic and tritium activities. Additional analyses for ; gross alpha activity are performed on the upstream water samples. Additional analyses for gross alpha activity and I-131 activity are performed on water samples taken from , the discharge flume. Tritium analyses are performed j quarterly from composites of monthly samples from all ! composite sample locations. Results of all gross beta analyses ranged from 1.7 to 4.9 pCi/l at the indicator locations and 1.8 to 6.1 pCi/l at the control location. Preoperational gross beta activity ranged from 1.1 to ,7. 6 pCi/1. These results are attributed to naturally occurring K-40 suspended as fine ! sediment particles in water. Other types of samples have l confirmed the presence of K-40 in Clinton Lake shoreline l and bottom sediments. Monthly surface water gross beta l activity for the composite sample locations are presented i graphically in Figure 12. Tritium analyses performed on samples were all less than l LLD. The preoperational tritium concentrations ranged from 220 to 330 pCi/1.

I G. Ouality Assurance Procram To establish confidence that data developed and reported g are accurate and precise, all REMP activities are incorporated into 3 the Illinois Power Company Quality Assurance (QA) program of audits and surveillances. The Quality Assurance program requires: Participation in intercomparison programs, such as the EPA cross-check program. A'n annual audit of the analysis laboratory functions and facilities. Periodic review of the Clinton Power Station procedures specifying sampling techniques. Duplicate analysis of every tenth sample assayed (not including TLDs). This requirement is to check laboratory precision. The routine counting of quality control samples. Approximately ten percent of the total number of counts performed are to be quality control counts. The analytical results provided by the laboratory were routinely reviewed by the Radiological Environmental Group of the Radiation Protection Department to ensure the required minimum sensitivities have been achieved and the proper analyses have been performed. Teledyne participates in the EPA cross-check program. The Teledyne participant code in the creas-check program is g CA. Participation in this program provides assurance that g the laboratory is capable of meeting widely-accepted criteria for radioactivity analysis, j Results of the 1996 cross-check program are shown in Appendix D. H. Chances to the REMP Durino 1996 Occasionally changes to the Radiological Environmental Monitoring Program are necessary to improve the monitoring of the environmental exposure pathways. These changes may result from items identified during the performance of the Annual Land Use Census, revised or new regulatory requirements, Quality Assurance audits or supplemental periodic and long-term sampling and analyses. During 1996, there were no changes to the REMP program. I 70

ANNUAL LAND USE CENSUS - -- i
IV. 1996 ANNUAL LAND USE CENSUS A land-use census is performed to ensure that changes in-the use of areas at and beyond the site boundary are identified and that any necessary modifications to the REMP are made. l The land use census is performed to identify within a i distance of 5 miles (8 km) , the locations in each of the 16 meteorological sectors of the nearest milk animals, the nearest residence and the nearest garden of gre'ater than 500
~
square feet producing broadleaf vegetation. Also, the ; census shall identify within a distance of 3 miles (5 km), ; the location in each of the 16 meteorological sectors of all milk animals and all gardens of greater than 500 square feet producing broadleaf vegetation.

(*) None identified within 8 kilometers of CPS in this meteoro' logical sector. l The Annual Land Use Census was conducted during the growing season satisfying the CPS Offsite Dose Calculation Manual t requirementa. Approximately 190 residences were surveyed by either direct contact, mailed in questionnaire, telephone, or direct observation. Data for this report was obtained using the following means: 4 o Performed door-to-door solicitation of residences / land owners identified in the previous
; year's Annual Land Use census and the most current I
71
I DeWitt County plat book.. If a resident was unavailable for questioning, a questionnaire was placed on their door to have them fill out and mail back. o Performed telephone solicitation of persons who wer<a unavailable during the door-to-door survey and didn't E mail back their questionnaire. E o By direct observation of land when the aforementioned methods were unsuccessful. If an individual was unable to be contacted, data from the previous year was used. Contacted several state and '.ocal agencies. The Annual Land Use Census results were examined to ensure that the REMP will provide representative measurements of radiation and radioactive materials in those exposure l pathways and for those radionuclides that lead to the 3 highest potential radiation exposures to the general public g resulting from Clinton Power Station operations. g Using the Annual Land Use Census results and utilizing effluent data supplied by the CPS Chemistry Group, an evalution is performed to ensure that the current ODCM sample location requirements are met. On the basis of this evaluation no changes to the REMP were made. l l Il I l I I m g;
i ! Summary of Changes Identified in 1996 Annual Land Use Census l Nearest Residence Three changes were identified for the nearest residence. These changes are shown below: 1995 Census Location 1996 Census Location 1.42 km E 1.55 km E 4.68 km SSW 4.90 km SSW 2.85 km NNW 2.82 km NNW Nearest Garden Over 100 gardens were identified in the 16 sectors sithin a 5-mile (8 km) radius of Clinton Power Station of which 55 produced broad leaf vegetation (e.g., lettuce and cabbage) and were greater than 50 m 2. In most cases, tomatoes, sweet corn and beans were grown in gardens identified. Changes in census locations for the nearest garden were identified in 10 of the 16 sectors and are shown below: 1995 Census Location 1996 Census Location 1.71 km NNE 3.76 km NNE 4.21 km ENE 2.78 km ENE 4.73 km SE >8 km SE 3.96 km SSE 4.19 km SSE 4.78 km S 6.49 km S 4.68 km SSW 5.00 km SSW 5.87 km SW 2.85 km SW 4.45 km WSW 6.98 km WSW 2.63 km W 3.35 km W 2.85 km NNW 3.76 km NNW Nearest Milk Animal Milking animals within 5 miles (8 km) were located in the 16 sectors surrounding CPS. Numerous locations were identified within the five-mile radius. With two exceptions, investigation of all locations revealed that none of the j cattle were " milking animals", as their milk was not being used for human consumption. The cattle were used for nursing of calves and meat production (both own use and meat , production). The only bovine milking animal was found in i l 73
I the we.st sector at 3.35 miles from the plant. After contacting the resident to see if they would be interested in providing milk samples they stated that they were no longer milking their cows. Since a routine sampling program could not be arranged with the owner this location could not be added to the Program. Goats were found at one location that were being " milked" and the milk is being used for human consumption. This location is currently a REMP milk sample location, however, it is not required per the ODCM but is still taken to serve as an indicator milk sample. No changes or additions to CPS REMP milk sampling locations were made as a result of the Annual Land Use census. Changes in the census locations for the nearest livestock / dairy were identified in 5 of the 16 sectors and are shown below: , 1995 Census Location 1.68 km N 1996 4.85 Census Location km NE I 3.46 km NE >8 km S

Column I Column 2 Column 3 Column 4 Column 5 Column 6 Column 7 TABLE EXPLANATIONS: Column 1: The Unit of Measurement describes all the numerical values for LLD, Mean and Range reported for a particular sample 3 3 . medium. For example: the Gross Beta LLD in AIR PARTICULATES is 0 010 pCi/m . Abbreviations used are: pCi/m picocurie per cubic metet of sampled air; mR/ quarter = exposure measured for calendar quarter period; pCi/1 = picocurie per liter of sample; pCi/g = picocune per gram of sample. Column 2: The Types of Analyses are desenbed as follows: Gamma Spec = measurement of each radioisotope in a sample usin Gamma Spectroscopy; Gross Betas and Gross Alphas = measurement of the radioactivity in a sample by measurement of emitted betas and alphas - no determination of individual radioisotopes is possible, Tritium = measurement of tritium (H-3) is sample by liquid scintillation counting rnethod, TLD = direct measurement of gamma exposure using i thermoluminescent dosimeters. Total number of analyses does not include duplicate analyses, recounts or reanalyses. Only ODCM required LLDs and detectable activity results are reported in this table Column 3: The ODCM required LLD is given is given when applicable LLD reported is the highest of those reported for each of analysis dunng the year; if all analyses reported positive values, no LLD is reported. It should be noted that, in most cases, the CPS REMP uses lower detection limits than required. l Column 4: Samples taken at indscator Locations during an operational radiological environmental monitonng program (REMP) reliably measure the quantities of any radioisotopes cycling through the pathways to man from the nuclear station. The reported values are the mean or average for the year of all samples of that type which had values greater than the LLD.
"f" is the fraction of all the samples taken at a!! indicator locations for the medium which reported values greater than the LLD. Example. 7 results greater than LLD out of 15 samples taken would be reported 7/15. The Range is the values of the lowest to highest sample resutts greater than LLD reported at all the indictor locations for that medium '

GLOSSARY activation - the process in which stable atoms become radioactive atoms by absorbing neutrons. ALARA - acronym for " As Low As Reasonably Achievable" which applies to many facets of nuclear power (i.e., radiation exposure for personnel kept low, minimizes number / activity 3 of effluent discharges). E alpha particle - a charged particle emitted from the nucleus of an atom having a mass and charge equal in magnitude to a helium nucleus which has two protons and two neutrons. atom - the smallest component of an element having all the properties of that element. Comprised of protons, neutrons and electrons such that the number of protons determines the element. background radiation - source of radiation that mankind has a no control over, such as cosmic (from sun) and terrestrial (naturally occurring radioactive elements) the g beta particle - a charged particle equivalent to an electron if negative or a positron if positive, originating l W near the nucleus of an atom during radioactive decay or fission. control location - a sample collection location considered to be far enough away from Clinton Power Station so as not to be affected by station operations. cosmic radiation - penetrating ionizing radiation originating from the sun and from outer space, varies from altitude and latitude. curie (Ci) - the unit of radioactivity equal : to 2.2 trillion disintegrations per minute. dead water - water that contains no tritium, dose - a quantity (total or accumulated) of ionizing radiation received. dose equivalent - a quantity used in radiation protection which expresses all radiations on a common scale for calculating the effective absorbed dose (the unit of dose g equivalent is the rem) g ecology - a branch of biology dealing with the relations between organisms and their environment. C-2
electromagnetic radiation - a traveling wave motion resulting from changing electric or magnetic fields. Familiar sources of electromagnetic radiation range from x-rays (and gamma rays) of short wavelength, through the ultraviolet, visible and infrared regions, to radar and radiowaves of relatively long wavelength. All electromagnetic radiation travels in a vacuum at the speed of light. element be
- one of 103 known chemical substances that cannot broken down further without changing its chemical properties.
environment - the aggregate of surrounding things, conditions, or influences. exposure - a measure of the ionization produced in air by x-ray or gamma radiation. Acute exposure is generally accepted to be large exposure received over a short period of time. Chronic exposure is exposure received over a long period of time. fission - process by which an atomic nucleus splits into two smaller nuclei and releases neutrons and energy. fission products - the nuclei formed as part of the fissioning of an atomic nucleus. gamma rays - high energy, short wavelength electromagnetic radiation emitted from the nucleus. half-life - the time required for half of a given amount of a radionuclide to decay. indicator location - a sample collection strategically placed to monitor dose rate or radioactive material that may be the result of Clinton Power Station operations. ionization - the process by which a neutral ' atom or molecule acquires a positive or negative charge. irradiation - exposure to radiation. Lower Limit of Detection (LLD) - the smallest amount of sample activity that will give a net count for which there is a confidence at a predetermined level that the activity is present. microcurie - one millionth of a curie and represents 2.2 million decays per minute. neutron - one of the three basic parts of an atom which has no charge and is normally found in the nucleus (center) of an atom. C-3
~
nucleus - the center of an atom containing protons and neutrons; determines the atomic weight and contributes to the net positive charge of an atom. nuclei (plural) nuclides - atoms which all have the same atomic number and mass number, periphyton - water plant life (i.e., algae). radiation - the process by which energy is emitted from a nucleus as particles (alpha, beta, neutron) or waves .(gamma). radionuclide - a radioactive species of an atom characterized by the constitution of its nucleus. The nuclear constitution is specified by the number of protons, number of neutrons, and energy content. rem - the unit of dose of any ionizing radiation that produces the 'ame biological effects as a unit of absorbed dose of ordinary x-rays. Acronym for Roentgen Equivalent Man. roentgen - a measure of ionization produced in air by x-ray or gamma radiation. statistics - the science that deals with the collection, classification, analysis and interpretation of numerical data by use of mathematical theories of probabilities. target tissue - any tissue or organ of the body in which radiation is absorbed. terrestrial radiation - source of radiation pertaining to the ground (Earth's crust) wind rose - a graphic representation indicating from which direction and speed the wind blew. x-rays - high energy, short wavelength electromagnetic radiation, emitted from the electron shells of an atom. m I
