Executive Summary The Radiological Environmental Monitoring Program for Seabrook Station operated without interruption for the period of January through December 2001. This report describes the REMP program and its implementation as required by Technical Specifications as defined in the Technical Requirements Manual. It also contains analytical results, data evaluation, dose assessment, and data trends for each environmental sample media. Also included are the results of the Land Use Census, historical data, and the Duke Engineering and Services Environmental Laboratory (DESEL) performance in the Quality Assurance Intercomparison Program required by the Technical Requirements Manual. Samples collected as part of the radiological environmental program included air particulates, charcoal filters, milk, ground water, surface (sea) water, sediment, fish, lobsters, shellfish, algae, vegetation and direct radiation. Radiological analysis on each sample included determination for both gamma and/or beta radiation. Any variability observed in the data is based on natural variables that can influence background radiation. The radionuclides identified as naturally occurring are K-40, Be-7, Th-232 and its daughter products. Cesium-137 was detected in milk as the result of fallout from atmospheric nuclear weapons testing. The levels detected are similar to those levels measured during the preoperational phase of the monitoring program. There is a decreasing trend in the number of positive samples identified. This is due to the natural decay of the residual Cs-137. Condition Reports relating to the REMP were entered into the Station Corrective Action Program. Specific condition reports are discussed in the applicable report section. In 2001, the maximum whole body dose to the hypothetically exposed individual was 0.0198 millirem. This whole body dose is the sum of all the exposure pathways for liquid and gaseous effluents, plus the direct whole body dose from station operations. This total dose represents approximately 0.08% of the whole body dose limit for a member of the public as set forth in 40CFRl90. The complete calculational methodology is submitted to the NRC as part of the Annual Radioactive Effluent Release Report. The results of the 2001 Radiological Environmental Surveillance Program continues to clearly demonstrate that there is no significant short term or chronic long term radiological impact on the environment in the vicinity of Seabrook Station from plant operations. No abnormal radiological characteristics were identified or observed in the surrounding environs. Plant effluents contribute no measurable radiation exposure to the general public as confirmed and assessed by the REMP. Environmental radiation levels measured on site, at the site boundary and near the nearest resident are at background levels. This is consistent with previous data. As a result, no increasing or decreasing trend exists. ii

ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 1.0 Introduction The North Atlantic Energy Service Corporation's (NAESCO) Radiological Environmental Monitoring Program at Seabrook Station has been designed and carried out to achieve the following specific objectives: To provide an indication of the appearance or accumulation of any radioactive material in the environment caused by the operation of the nuclear power station. To provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits. To verify the adequacy and proper functioning of station effluent controls and monitoring systems. To provide standby monitoring capability for rapid assessment of risk to the general public in the event of unanticipated or accidental releases of radioactive material. North Atlantic Energy Service Corporation collected the terrestrial samples. Normandeau Associates, Inc. collected the marine and sediment samples. After initial processing, the samples were sent to the Duke Engineering & Services Environmental Laboratory (DESEL) in Marlborough, Massachusetts for further processing and radionuclide analysis. The DESEL also processed the environmental thermoluminescent dosimeters (TLD's). This report is a summary of the findings of the Radiological Environmental Monitoring Program for 2001. It is being provided in compliance with Part A of Seabrook Stations Offsite Dose Calculation Manual (ODCM) and Technical Specification 6.8.1.3 as defined in the Technical Requirements Program (TRP) Manual 5.2-10.1. 1
2.0 Environmental Monitoring Program In this section, Table 2.1 outlines the monitoring program as specified in section TRP5.2-9.1 of the Technical Requirements Manual.

FIGURE 2.6 DIRECT RADIATION MONITORING LOCATIONS OUTSIDE 12 KILOMETERS OF SEABROOK STATION 3.0 Summary of Radiological Environmental Data The following pages summarize the analytical results of the environmental samples, which were collected in 2001. Each environmental media category is presented as a separate subsection. A table that summarizes the data follows a discussion of the sampling requirements and results for each program. Listed at the top of each table are the units of measurement for each medium. The left-hand column contains the radionuclide, which is being reported, total number of analyses of that radionuclide, and the number of measurements that exceed ten times the yearly average of control measurements. The latter are classified as "non- routine" measurements. The next column lists the Lower Limit of Detection (LLD) for those radionuclides which have detection capability requirements specified in the Off-Site Dose Calculation Manual. Those sampling stations which are adjacent to the plant and which could conceivably be affected by the operation of Seabrook Station are called "Indicator" or "Zone 1" stations. Distant stations, which are beyond potential plant influences, are called "Control" or "Zone 2" stations. Direct radiation (TLD) monitoring locations are subdivided into site boundary, inner ring, and outer ring (emergency response) stations. A set of statistical parameters is calculated for each radionuclide. This set of statistical parameters includes separate analyses for (1) the indicator stations, (2) the station having the highest annual mean concentration for that radionuclide, (3) and control stations. For each of these three groups of data, these parameters are as follows:
- The mean value of all concentrations.
- The range of values.
The number of positive measurements (a concentration which is greater than the a posteriori LLD for that analysis) divided by the total number of measurements. Each single radioactivity measurement in media datum in this report is based on a single measurement and is reported as a concentration plus or minus a one standard deviation uncertainty. The quoted uncertainty term represents only the random uncertainty associated with the radioactive decay process (counting statistics), and not the propagation of all possible uncertainties in the analytical procedure. Attachment I contains the data for the samples collected in 2001. The results are organized by sample type, within each sample type listing the data is alphabetical by nuclide, within each nuclide listing the data is chronologically arranged by end date (date of sample collection). The radionuclide value concentrations (charcoal media) have been corrected for radioactive decay to the end of the collection. The airborne radioiodine (charcoal) concentrations have been calculated assuming a constant flow rate and concentration throughout the collection period and correcting for decay while sampling as well as between sample collection termination and analysis. Pursuant to ODCM requirements, any concentration below the LLD for its analysis is reported as "not detected". These values are set to zero for averaging purposes. Where a range of values is reported in the tables of this section, values less than the a posteriori LLD for the analysis are reported as zero. 13
A) Air Particulate Air monitoring stations were established at a total of eight locations (Five are required by the Offsite Dose Calculation Manual). Seven of the locations are indicators, while the remaining one is a control station. Airborne particulates are collected by passing the air through a glass-fiber filter. These filters are collected weekly and held for at least 100 hours before being analyzed for gross-beta activity (indicated as GR-B in tables) to allow for the decay of radon daughter products. For the year, 423 particulate filters were collected for gross beta activity. One weekly air sample was not collected and analyzed. The gross beta activity for the indicator locations is statistically equivalent to that seen at the control station. The gross beta results for all stations is also similar to what was seen in the preoperational program and for the last nine years of commercial operation. Fluctuations seen in the gross beta activity throughout the year can be attributed to changes in the environment. Concentrations of naturally occurring radionuclides in the atmosphere directly above land are affected by natural environmental processes such as wind direction, precipitation, snow cover, and soil temperature and moisture. No plant related gamma-emitting radionuclides were detected in any of the quarterly composite air filters samples analyzed. Therefore no increasing or decreasing trend exists. In 2001, naturally occurring Be-7 was the only nuclide detected. Be-7 is of cosmogenic origin. This is consistent with previous years both pre and post operationally. For week #32, air sample station #1 was found to be off at the time of filter change out. A sample was not available for collection. Two Condition Reports (CR) were initiated. The second CR provides more detail as to disposition. The Kurz air sample pump was replaced. The air particulate sampling program demonstrated no off-site dose to the public or impact to the environment, from this pathway, as the result of plant operations. This is consistent with previous years and the preoperational program. 14

B) Charcoal Filters Charcoal filter cartridges are in series with the air particulate glass-fiber filters. Monitoring stations were established at a total of eight locations (five are required by the ODCM) . Seven of these are indicators and one is a control. Charcoal filters from the air sampling stations were collected and analyzed weekly for 1-131 activity. During 2001, A total of 423 charcoal cartridges from all eight locations were analyzed. As was the case with particulate air samples, one samples were missed for the year (see section A). No sample analysis indicated a detectable measurement for 1-131 that was statistically relevant (positive) at the air sampling locations stated in the ODCM and as stated in the Technical Requirements Manual. The REMP program has detected no radioiodine at any offsite air sample location, since Seabrook Station's initial criticality of June 1989. There is no dose to the public or impact to the environment from this pathway. The preoperational data for 1-131 are consistent with present data. Therefore, no increasing or decreasing trend exists. 22

C) Milk Milk samples were collected every two weeks during the pasture season and monthly at other times. Samples are analyzed for 1-131 and gamma-emitting radionuclides. Milk samples were collected from four indicator and two control locations for the year. Three of the indicator locations and one control are required by Technical Specifications. The required Indicator locations range from 5.2 to 6.9 km from the Plant while the Control location is 17 km from the Plant. A CR was generated in the first quarter of 2001 to document the fact that a backup control station went out of business. This occurrence was documented in the 2000 submittal. A total of 90 milk samples were collected within the year. Each sample was analyzed for gamma emitting radionuclides. In addition, all samples are evaluated for 1-131 through an iodine extraction process. Gamma analysis indicated only potassium-40 and cesium-137 was present. Detectable concentrations of Cs-137 were measured in several samples collected in 2001. Four positive results for Cs-137 were detected at required location TM
- 16. It has been shown in the preoperational program that this nuclide is the result of atmospheric nuclear weapons testing that persists in the environment. The levels of Cs-137 detected in 2001 are consistent with that detected in the pre-operational phase and during the first nine years of commercial operations.
Potassium-40 was detected in all indicator and control locations. Potassium-40 is a naturally occurring nuclide detected in many environmental sample media. Iodine-131 was not positively identified at any required or added location for the year. The samples met the Lower Limit of Detection (LLD) requirements (1 pCi's/kg) for 1-131 in milk. This is consistent with previous years for both the pre-operational and operational phases of the program. The calculated dose as the result of plant effluents is not evaluated due to the fact that no plant related radionuclides were detected. The milk-sampling program demonstrated that there is no impact to the public or environment, through this pathway, from plant operations. Therefore, no increasing or decreasing trend exists. 24

D) Surface Water Surface water (seawater) grab samples are required at two locations (control and indicator) monthly. The indicator (01) is over the vicinity of the plant discharge. The control location (51) is located in Ipswich Bay, MA. A gamma analysis is performed on each sample. A tritium analysis is performed on the quarterly composite of these samples. For the year, 23-gamma analyses were performed on surface water samples. A CR was generated to document the fact that a seawater sample was not collected from the control location (Ipswich Bay) for week #8. This was due to heavy weather and high seas for the prescribed collection period. The only radionuclide detected in 2001 was naturally occurring K-40. No plant related nuclides were detected. The present data for gamma emitters in seawater is consistent with that of the pre-operational program and the last twelve years of operations. Therefore, no increasing or decreasing trend exists. Quarterly composites from the same gamma collection samples were analyzed for tritium. Eight samples were analyzed in 2001. The monthly composites showed no presence of tritium. The composites met the required LLD (3000 pCi's/kg) for tritium in seawater. These results are consistent with preoperational tritium data. The calculated dose, as the result of plant effluents is not evaluated due to the fact that no plant related radionuclides were or have been detected. Therefore, no increasing or decreasing trend exists. This sampling program demonstrates that there is no impact to the public or environment, through this pathway, from plant operations. 31

E) Ground Water There is no requirement to collect ground water samples. For the year, four quarterly ground water samples were collected from two locations. These samples were analyzed for gross-beta activity, gamma-emitters and tritium. These samples were collected from the drinking water line supplied to the Site (by the Town of Seabrook) and from an inactive well located approximately 1 km North of the plant. One CR was generated that concerned a missed gross beta analysis for week #49. The samples were subsequently reanalyzed for the missed gross beta test. Gross beta activity was detected in seven of the eight samples taken and is due to naturally occurring radium and its daughter products. The gross beta activity seen at both locations is similar to what was seen in the preoperational program and are consistent with results over the last ten years of commercial operations. No tritium or gamma emitters were detected. The calculated dose is not evaluated due to the fact that plant related radionuclides have not been detected. Therefore no increasing or decreasing trend exists. There is no impact to the public, through this pathway, from plant operations. 34

F) Sediment Semiannual sediment sampling is required at one location, although a total of five locations, three indicators and two controls, are collected. The indicator stations are comprised of two beach sediment cores from Seabrook Beach and one subtidal sediment core taken from near the discharge structure. The control locations, both beach and subtidal, are both located within Ipswich Harbor. A total of 30 samples were collected for the year from all locations. Each sediment core was sectioned into 5-centimeter segments. Segment 1 extends from the top of the core to 5 centimeters, segment two extends from 5 to 10 centimeters and the third segment extends from 10 to 15 centimeters in depth. A gamma analysis was performed on each segment. The only radionuclides detected in 2001 were naturally occurring K-40 and Th-232 with its natural daughters. Potassium-40 was detected in all core samples at all depths from all locations. Thorium-232 and its daughters were present in 13 of the 18 indicator segments and in 9 of the 12 control segments. No plant related radionuclides were detected in any segment. No increasing or decreasing trend exists. This is consistent with the preoperational program and with previous years of plant operations. There is no dose to the public or impact to the environment from any pathways associated with these media. 39

G) Fish Semiannual fish and invertebrate samples are required from two locations. The Program calls for samples to be collected quarterly from two locations. This section presents the results for fish sampling only. Invertebrate results may be found in sections entitled Lobsters and Shellfish. A CR was generated to document that fish were not collected for the first Quarter. This was due to the lack of fish in the prescribed areas. The contractor Normandeau Associates was unable to collect fish from either the indicator or control locations. Procedural collection steps were met as net towing was attempted for approximately 4 hours at the designated locations. During the year, the fish species collected from station no.03 (indicator station) were Winter and Yellow Tail Flounder. Species collected from station no.53 (control station) were Winter Flounder. A gamma analysis was performed on each sample collected. In 2001, the only radionuclide detected in fish samples was natural occurring K-40. No plant related radionuclides were detected. No increasing or decreasing trend exists. Subsequently, there is no dose to the public or impact to the environment, through this pathway, from plant operations.

H) Lobsters Semiannual fish and invertebrate samples were required from two locations. This section provides the results for one type of invertebrate - Homarus americanus (American lobsters). Fish and other invertebrate results may be found in the sections entitled Fish and Shellfish, respectively. Samples were collected from two locations semiannually. During the year, lobsters were collected from an indicator location near the discharge and from a control location within Ipswich Bay. A total of four samples were collected for the year. A gamma analysis was performed on each sample. The only radionuclide detected in lobster samples in 2001 was natural occurring K-40. No plant related radionuclides were detected. Therefore, no increasing or decreasing trend exists. Subsequently, there is no dose to the public or impact to the environment, from this pathway, from plant operations. This is consistent with the last twelve years of plant operations as well as the preoperational program. 45

I) Shellfish Semiannual fish and invertebrate samples are required from two locations. This section provides the results for shellfish samples only. Fish and other invertebrate results may be found in the sections entitled Fish and Lobsters, respectively. During the year there were two species of mussels harvested for analysis. Modiolus (horse mussels) were collected, by divers, from near the discharge outfall (indicator station) and from Ipswich Bay (control). Mytilus (blue mussels) were collected from the intratidal areas of Seabrook Harbor (indicator) and Plum Island, MA (control). Eight samples were collected for the year. A gamma analysis was performed on each sample. The only radionuclide detected in shellfish samples in 2001 was natural occurring K-40. No plant related radionuclides were detected. Therefore, no increasing or decreasing trend exists. Subsequently, there is no dose to the public or impact to the environment, from this pathway, from plant operations. This is consistent with the preoperational program and with previous years of plant operations. 48

J) Irish Moss There is no requirement to collect Irish Moss samples. Semiannual Chondrus (Irish Moss) samples were collected from an indicator area near plant discharge and a control location within Ipswich Bay. Four samples were collected for the year. A gamma analysis was performed on each sample. The only radionuclides detected in 2001 were naturally occurring Be-7 and K-40. Potassium 40 was found in all samples analyzed. No plant related radionuclides were detected. Therefore no increasing or decreasing trend exists. Subsequently, there is no dose to the public or impact to the environment, through this pathway, from plant operations. This is consistent with the preoperational program and with previous years of plant operations. 51

K) Food Crop There is no requirement for food crop samples as long as the required milk locations are available. Samples were collected from three to four locations in the growing season months. Strawberries (June), green beans (July), and corn (August) were collected. For the year, a total of nine samples were collected. A CR was generated to reflect a name change to one of the farms where food crops are collected. This CR also addressed the issue of utilizing a scale that is more user friendly regarding alignment and calibration. A gamma analysis was performed on each sample. The only radionuclide detected in 2001 was natural occurring K-40. Potassium 40 was detected at all locations both indicator and control for the three months sampled. Potassium 40 was not detected at the control station for the June time period. No plant related radionuclides were detected. Therefore, no increasing or decreasing trend exists. Subsequently, there is no dose to the public or impact on the environment, through this pathway, from plant operations. This is consistent with the preoperational program and with previous years of plant operations. 54

L) Direct Radiation Direct gamma radiation exposure was measured with thermoluminescent dosimeters (TLDs). Two Panasonic UD-814 TLD badges are placed at each of the monitoring stations. Each TLD badge has 3 CaSO4 :Tm elements. A location result is an average of six independent readings per quarter. A total of forty-seven stations are located offsite, forty of which are required. The badges were collected and readout on a quarterly schedule. The exposure rates were normalized to a 91-day quarter. A summary of the data is shown in Table 3.1. Overall, the REMP direct radiation program showed no indication of increased direct radiation above background either within the owner-controlled area or beyond the site boundary. This is demonstrated by the fact that indicator location results are statistically identical to control locations. The annual mean of all indicator locations was 16.2 mrem while the mean of all control locations was 17.4 mrem. This verifies that there is no difference in the annual dose as a function of distance from the plant. The 2001 TLD direct radiation program, when compared to the previous years of operational data and the pre-operational program, shows no significant trends relative to increased dose rates in the environment. A CR was generated in January 2001 for a missing TLD (badge #23) that was part of the 2000 fourth quarter change out. The local utility company (where the TLD was located) unintentionally destroyed the badge when it replaced the utility pole where the badge was located. No further corrective actions were implemented. The direct radiation-monitoring program demonstrated that there was no offsite dose to the public or impact to the environment from the operation of the plant. 57

4.0 Quality Assurance Program The quality assurance program at the Duke Engineering & Services Environmental Laboratory is designed to serve two overall purposes:
- 1) Establish a level of confidence in the measurement process to assure the licensee, regulatory agencies and the public that analytical results are accurate and precise; and 2) Identify deficiencies in the sampling or the measurement process to those responsible for these operations so that corrective actions can be taken. Quality assurance is applied to all steps of the measurement process, including the collection, reduction, evaluation and the reporting of data, as well as the record keeping of the final results. Quality control, as part of the quality assurance program, provides a means to control and measure the characteristics of measurement equipment and processes, relative to established requirements.
The DESEL employs a comprehensive program to monitor the quality of analytical processing to ensure reliable environmental monitoring data. The program includes the use of approved and controlled procedures for all work activities, a nonconformance and corrective action tracking program, systematic internal audits, audits by external groups, a laboratory quality control program, and a staff training and retraining program. Monitoring programs include the Intralaboratory Quality Control Program administered by the Laboratory QA Officer (used in conjunction with National Institute Standards and Technology's Measurement Assurance Program, NIST MAP) and the third party interlaboratory programs administered by the US EPA and Analytics, Inc. These programs are targeted to supply QC\QA sources at 5% of the routine sample analysis load. In addition, the Laboratory Quality Control Audit Committee administers and approves a blind duplicate quality assurance program conducted through client environmental monitoring programs. Environmental TLD Program The Panasonic environmental dosimeters are processed by the DESEL, which is a National Voluntary Laboratory Accreditation Program (NVLAP) certified laboratory. The NVLAP is conducted through the Battelle Pacific Northwest Laboratories. The DESEL environmental TLD program has its own quality assurance program, through the Laboratory Quality Assurance Officer, as well as the NVLAP program. Under these programs, dosimeters are irradiated to ANSI specified testing criteria and submitted for processing to the Dosimetry Services Group as "unknowns". The bias and precision of TLD processing is measured against this standard and is used to indicate trends and changes in performance. Instrument checks, although routinely performed by the Dosimetry Services Group and representing between 5-10% of the TLD's processed, are not part of this report because they do not represent a true process check sample since the doses are known. The DESEL and the third party tester conducted eighty-four independent performance tests in 2001. Of these, 60 TLD's were submitted to the Dosimetry Services Group and 24 were submitted to the Battelle Pacific Northwest Laboratories testing program. The TLD's met the acceptance criteria for bias (+/- 20.1%) and precision (+/- 12.8%). Test Number of Bias % +/- Precision Organization Dosimeters (Std. Dev) % (Std Dev)% Tested Third Party 24 2.7 +/- 5.3 1.1 DESEL 60 0.9 +/- 3.3 1.4 All irradiation's made to Category IV (Cs-137) 78
Intralaboratory Quality Control Program The DESEL conducts an extensive intralaboratory quality control program to assure the validity and reliability of the data. This program includes quality control of laboratory equipment, use of reference standards for calibration, and analysis of blank and spiked samples. Process check samples are either samples submitted in duplicate to evaluate the precision of the measurement or spiked with a known quantity of radioactive material to assess the bias in the measurement. The Laboratory QA Officer reviews the records of the quality control program. Corrective measures are taken whenever applicable. Summaries of the program process check results are found in Table 4.1. Of the 290 analyses, 97.9% passed the bias criteria and 100% of the results evaluated for precision were acceptable. Third Party Intercomparison Program The DESEL participates in a third party cross check program managed by Analytics Inc. to satisfy the requirement of the Environmental Technical Specification/ODCM. The DESEL Analytics program was originally used to augment the EPA Intercomparison Program that it now replaces. The current program is designed to be comparable to the pre-1996 EPA PE Program in terms of the number of samples, matrices and nuclides. The results for the 4 th quarter 2000 through the 3 rd quarter 2001 are summarized in Table 4.2. Each sample is analyzed in triplicate and the results are evaluated against the internal acceptance criteria described in the DESEL Manual 100-Laboratory Quality Assurance Plan. This acceptance protocol is used for all inter-laboratory programs with no pre-set acceptance criteria. When results fall outside of the acceptance criteria, an investigation is initiated to determine the cause of the problem and if appropriate, corrective measures are taken. The DESEL internal acceptance criteria are summarized at the end of Table 7.2. During this reporting period, 96.5% passed the bias criteria and 99.2% passed the criteria for precision. There were three DESEL Condition Reports (CR's) for third party intercomparison "Analytics Inc" that were described in the 2000 Report, they are: DESEL CR 00 a non-agreement for gross alpha/radium in water was a sample preparation issue; DESEL CR 00 Non-agreement for Cr-521 in milk was due to poor counting statistics; DESEL CR 01 Non-agreement for 1-131 in milk involved sample control; All the above issues have been addressed and closed out. In 2001, three Analytics results fell outside the 'agreement' category. Three CR's were issued. DESEL CR 01-07 A non-agreement for Sr-89 on a filter. This CR has been closed out; DESEL CR 01-41 Np-237 in a water sample fell outside the acceptance criteria for bias. Prior residual contamination was the cause for the high sample bias; DESEL CR 02-01 Acceptance criteria exceeded for Sr-89 in milk. Evaluation is pending and will be reported in the 2002 submittal. 79
Blind Duplicate Quality Assurance Program The Laboratory Quality Control Audit Committee (LQCAC) is comprised of representatives from several New England DESEL clients. Two of the primary functions of the LQCAC have been to conduct an annual audit of Laboratory operations and to coordinate the Blind Duplicate Quality Assurance Program. Under the Blind Duplicate Quality Assurance Program, samples are split from homogeneous environmental media by the client and sent to the DESEL for analysis. They are "blind" in that the identification of the matching sample is not identified to the Laboratory. Participating clients submitted a total of 31 paired samples in 2001. The measurements evaluated include twenty-five gamma emitting radionuclides, H-3, Sr-89, Sr-90, 1-131 and gross-beta. All measurements are evaluated, whether the results are statistically positive or not, and whether the net concentration is positive or negative. The samples submitted as part of this program are listed in Table 4.3. Table 4.4 presents the results of the Blind Duplicate Program by analysis type for each participating company. For the 2001 program, 99.4% of the measurements met the DESEL internal acceptance criteria as specified in reference #3. The number of paired references falling outside the acceptance criteria are listed before the dash (/) in each company column. Totals are presented for each participating company as well as the entire program. 80

5.0 Land Use Census Technical Requirements Program (TRP 5.2C.9.2.1) requires that a Land Use Census be conducted annually to identify the location of the nearest residence, milk animal and nearest garden of greater than 50 square meters producing broad leaf vegetation in each of the 16 meteorological sectors within five miles of the plant. The 2001 census was completed in accordance with the requirements of the ODCM. The census is used to identify the location of the nearest milk animal, the nearest residence, and the nearest garden of 50 square meters within five miles of plant. In 2001, A global positioning system was used. The nearest resident, garden and milk animal locations identified in the 2001 Land Use Census and their distances are shown in Table 5.1. The results of this census showed that the sampling locations currently being used have the highest calculated dose commitment. 87
