Executive Summary This report on the Radiological Environmental Monitoring Program conducted for the Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 1 January 2005 through 31 December 2005. During that time period, 1,070 analyses were performed on 910 samples.

Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No tritium, fission or activation products were found.

Drinking water samples were analyzed for concentrations of gross beta, tritium, and gamma emitting nuclides. No fission or activation products were found. Gross beta and tritium activities detected were consistent with those observed in previous years.

The remaining sample media representing the aquatic environment included fish and sediment samples. These media were analyzed for concentrations of gamma emitting nuclides. Fish samples showed no detectable fission or activation products from the operation of PBAPS. Cesium-137 activity was found at most sediment locations and was consistent with data from previous years. Co-60 and Mn-54 were found at the nearest downstream sediment sampling location.

The dose to a teenagers skin from the sediment pathway was calculated to be 1.94 E-03 mrem/year, which represents 0.010% of the allowable fraction of 10 CFR 50, Appendix I limits.

The dose to a teenagers whole body from the sediment pathway was calculated to be 1.65 E-03 mrem/year, which represents 0.027% of the allowable fraction of 10 CFR 50, Appendix I limits.

The atmospheric environment was divided into two parts for examination: airborne and terrestrial.

Sample media for determining airborne effects included air particulates and air iodine samples. Analyses performed on air particulate samples included gross beta and gamma spectrometry. No fission or activation products were found. The gross beta results were consistent with results from the previous years. Furthermore, no notable differences between control and indicator locations were observed. These findings indicate no measurable effects from the operation of PBAPS.

High sensitivity Iodine-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.

Examination of the terrestrial environment was accomplished by analyzing milk and food product samples. Milk samples were analyzed for low level concentrations of Iodine-131 and gamma emitting nuclides. No activation or fission products were found. Food product samples were analyzed for concentrations of gamma emitting nuclides. Concentrations of naturally occurring Be-7 and K-40 were detected. No activation or fission products were detected.

Ambient gamma radiation levels were measured quarterly throughout the year. All measurements were below 10 mR/standard month and the results were consistent with those measured in previous years.

The results of the TLD monitoring program were used to determine if the Independent Spent Fuel Storage Installation (ISFSI) had any measurable impact on the dose rate in the environs. One on-site location showed an increase dose of 0.5 to 1 mR per standard month.

No increase in dose was evident at the nearest residence.

The control milk farm A in the WSW sector at 30,493 feet went out of the milking business. The control farm was replaced by farm T in the W sector at 34,581 feet.

No milk samples were missed as a result of the change of milk farms.

TLD 1 K was added in the SW sector at 4,604 feet. The TLD was added to comply with ODCMS Table 4.8. E. 1.1 requirement for TLD stations in the general area of the SITE BOUNDARY and a residence at the location.

Food products were sampled on Oct. 6, 2005 at three locations:

55 at about 9.9 miles in the NE sector 2B at about 0.7 miles in the SSE sector 1 Q at about 0.8 miles in the WNW sector In assessing all the data gathered for this report and comparing these results with preoperational data, it was evident that the operation of PBAPS had no adverse radiological impact on the environment.

Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature, gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 March 1966.

Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 1974. For the purposes of the monitoring program, the beginning of the operational period for Unit 1 was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report (1). PBAPS Units 2 and 3 are boiling water reactors, each with a power output of approximately 1170 MWe. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973.

Criticality was achieved on 16 September 1973, and full power was reached on 16 June 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 July 1974. Criticality was achieved on 7 August 1974, and full power was first reached on 21 December 1974.

Preoperational summary reports (2)(3) for Units 2 and 3 have been previously issued and summarize the results of all analyses performed on samples collected from 5 February 1966 through 8 August 1973.

A Radiological Environmental Monitoring Program (REMP) for PBAPS was initiated in 1966. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry, and Environmental Inc. (Midwest Labs) on samples collected during the period 01 January 2005 through 31 December 2005.

A.

Objectives The objectives of the REMP are:

1.

Provide data on measurable levels of radiation and radioactive materials in the site environs.

2.

Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

B.

Implementation of the Objectives Implementation of the objectives is accomplished by:

1. Identifying significant exposure pathways.

2. Establishing baseline radiological data of media within those pathways.

3. Continuously monitoring those media before and during plant Station operation to assess Station radiological effects (if any) on man and the environment.

Program Description A.

Sample Collection Normandeau Associates Inc., (NAI), collected samples for the PBAPS REMP for Exelon Nuclear. This section describes the general collection methods used by NAI to obtain environmental samples for the PBAPS REMP in 2005.

Sample locations and descriptions can be found in Table B-1, and Figures B-1 through B-3, Appendix B. The collection procedures used by NAI are listed in Table B-2, Appendix B.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, fish, and sediment. Surface water from two locations (11LL and 1MM) and drinking water from two locations (4L and 61) were collected weekly by automatic sampling equipment. Weekly samples from each of the surface and drinking water locations were composited into a separate monthly sample for analysis.

Approximately, two quarts of water were removed from the weekly sample container and placed into a clean two-gallon polyethylene bottle to form a monthly composite.

Control locations were 1LL and 61.

Fish samples comprising the flesh from two groups: Bottom Feeder (catfish) and Predator (smallmouth bass, largemouth bass, or bass) were collected semiannually from two locations: 4 and 6 (control).

Sediment samples composed of recently deposited substrate were collected semiannually at three locations:

4J, 4T and 6F (control). An additional set of sediment samples was collected in December to validate results.

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on air particulate, airbome iodine and milk samples. Air particulate and air iodine samples were collected and analyzed weekly from five locations (1 B, 1Z, IC, 3A, and 5H2). The control location was 5H2. Airborne iodine and particulate samples were obtained at each location using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately 1 cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.

Milk samples were collected biweekly at six locations (A (T), J, 0, R, and S) from April through November and monthly from December through March.

Seven additional locations (B, C, D, E, L, and P) were sampled quarterly.

Locations A, B, C, E and T were controls. All samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.

Food product samples were collected annually at three locations (1Q, 2B, and 55) in October. All samples were collected in new unused plastic bags and shipped promptly to the laboratory.

Ambient Gamma Radiation Direct radiation measurements were made using Panasonic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed on and around the PBAPS site as follows:

A site boundaryQdng, consisting of 19 locations (1L, 1P, 1A, 1Q, 1D, 2, 1M, 1R, 11, 1C, UJ, 1K, IF, 40, 1NN, 1H, 1G, 1B, and 1E), near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual off-site doses) from PBAPS releases.

An intermediate distance ring, consisting of 19 locations (15, 22, 44, 32, 45, 14, 17, 31A, 4K, 23, 27, 48, 3A, 49, 50, 51, 26, 6B, and 42), extending to approximately 5 miles from the site and designed to measure possible exposures to dose-in population.

The balance of nine locations (28, 43, 5, 16, 24, 46, 47, 18, and 19) representing control and special interests areas such as population centers, schools, etc.

The specific TLD locations were determined by the following criteria:

1.

The presence of relatively dense population;

2.

Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the site, where estimated annual dose from PBAPS, if any, would be more significant;

3.

On hills free from local obstructions and within sight of the vents (where practical);

4.

And near the dwelling closest to the vents in the prevailing down wind direction.

Two TLDs - each comprised of three CaSO4 themoluminescent phosphors enclosed in plastic - were placed at each location in a Formica "birdhouse" or polyethylene jar located approximately six feet above ground level. The TLD sets were exchanged quarterly, then sent to the laboratory for analysis.

B.

Sample Analysis This section describes the general analytical methods used by Teledyne Brown Engineering and Environmental Inc. to analyze the environmental samples for radioactivity for the PBAPS REMP in 2005. The analytical procedures used by the laboratories are listed in Table B-2, Appendix B.

In order to achieve the stated objectives, the current program includes the following analyses:

1.

Concentrations of beta emitters in drinking water and air particulates.

2.

Concentrations of gamma emitting nuclides in surface and drinking water, air particulates, milk, fish, sediment and food products.

3.

Concentrations of tritium in surface and drinking water.

4.

Concentrations of 1-131 in air and milk.

5.

Ambient gamma radiation levels at various site environs.

C.

Data Interpretation The radiological and direct radiation data collected prior to PBAPS becoming operational was used as a baseline with which these operational data were compared.

For the purpose of this report, PBAPS was considered operational at initial critically. In addition, data were compared to previous years' operational data for consistency and trending. Several factors are important in the interpretation of the data. These factors were important in the interpretation of the data:

1.

Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD was intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required PBAPS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2.

Net Activity Calculation and Reporting of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations will result in sample activity being lower than the background activity effecting a negative number. An MDC was reported in all cases where positive activity was not detected.

Gamma spectroscopy results for each type of sample were grouped as follows:

For surface and drinking 12 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140, and La-140 were reported.

For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

For sediment six nuclides, K-40, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

For milk five nuclides, K-40, Cs-134, Cs-137, Ba-140, and La-140 were reported.

For food product seven nuclides, Be-7, Mn-54, Co-58, Co-60, 1-131, Cs-134, and Cs-137 were reported.

Means and standard deviations of the results were calculated. The standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

D.

Program Exceptions For 2005 the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1. The air particulate and iodine sampler 5H2 (control) had a loss of power due to a transformer failure. The transformer was repaired prior to the next period as required by the ODCM.

2. Air particulate and iodine sampler 1C had a pump performance issue.

The pump was repaired prior to the next sample period as required by the ODCM.

3. A NRC non-cited violation was issued for failure to sample food products in the highest D/Q sectors if milk sampling was not performed in the highest D/Q sectors. Food products were sampled on October 6, 2005 at three locations.

55 at about 9.9 miles in the N sector 2B at about 0.7 miles in the SSE sector 1Q at about 0.8 miles in the WNW sector Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent a recurrence.

Occasional equipment breakdowns and power outages were unavoidable.

E.

Program Changes Drinking water analysis of soluble and insoluble fractions was discontinued in December 2004. Drinking water is being analyzed for total gross beta.

The drinking water data for the soluble and insoluble fractions was combined to create the total gross beta graph in Appendix C, Figure C-1.

The previous data included summation of the less than values.

Milk farm A (control) went out of the milking business and was replaced by farm T at about 5.7 miles in the W sector.

TLD station 1 K was added 10/07/05.

Food products were added to the PBAPS program in October 2005.

IV.

Results and Discussion A.

Aquatic Environment Samples were taken from a continuous sampler at two locations (1 LL and 1MM) on a monthly schedule. Of these locations, 1MM located downstream, could be affected by Peach Bottom's effluent releases.

The following analyses were performed:

Tdium Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-I.1, Appendix C).

No tritium activity was detected. Results ranged from <155 to <198 pCi/I and averaged 176 pCi/I at the control location and 166 pCi/I at the indicator location.

Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nudides (Table C-1.2, Appendix C). All nuclides were less than the MDC.

2.

DrnigWt Monthly samples were collected from continuous water samplers at two locations (4L and 61).

One location (4L) could be affected by Peach Bottom's effluent releases.

The following analyses were performed:

Gross Beta Samples from both locations were analyzed for concentrations of total gross beta activity (Tables C-I1.1 and Figures C-1 Appendix C). The values ranged from <2.2 to 8.8 pCi/I. Concentrations detected were generally below those detected in previous years.

Triium Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-11.2, Appendix C). Positive trtium activity was detected in two of eight samples. The concentrations detected, 187 and 191 pCi/L, were from downstream and upstream sample points respectively. The tritium came from upstream and not from Peach Bottom Atomic Power Station.

Gamma Spectrometr, Samples from both locations were analyzed for gamma emitting nuclides (Table C-I1.3, Appendix C). All nuclides were less than the MDC.

3.

Eihb Fish samples comprised of bottom feeder (catfish) and predator (bass) were collected at two locations (4 and 6) semiannually.

Location 4 could be affected by Peach Bottom's effluent releases.

The following analysis was performed:

Gamma Spectrometry The edible portion of fish samples from both locations was analyzed for gamma emitting nudides (Table C-111.1, Appendix C). Naturally occurring K-40 was found at all stations and ranged from 2,710 to 3,260 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Historical levels of Cs-1 37 are shown in Figure C-3, Appendix C.

4.

Sediment Aquatic samples were collected at three locations (4J, 4T and 6F) semiannually. Of these locations two, 4J and 4T located downstream, could be affected by Peach Bottom's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were naturally occurring Be7 and K-40. Radioactive nuclides Mn-54 and Co-60 originating from Peach Bottom were found at location 4J.

Beryllium-7 was found at one location with a concentration of 1,080 pCi/kg dry. Potassium-40 was found at eight of nine samples in all locations and ranged from 10,100 to 22,500 pCi/kg dry.

Manganese-54 was found at location 4J in two of three samples at concentrations of 36 and 61 pCi/kg dry.

Cobalt-60 was found at location 4J in two samples at concentrations of 144 and 174 pCi/kg dry. Concentrations of the fission product Cs-137 were found in five of nine sediment samples in all locations. Location 4T had the highest average concentration Cs-137 of 133 pCi/kg dry. The activity of Cs-137 detected was consistent with those detected in the pre-operational years (Figure C-4, Appendix C). No other Peach Bottom fission or activation products were found.

The shoreline doses due to the activity in the sediment were calculated using the methodology of Regulatory Guide 1.109, Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance With 10 CFR Part 50, Appendix I. The following nudides concentrations (Pu-238, Pu-239, Pu-241, Am-241, Cm-242 and Cm-244, C-14, Ni-63 and Tc-99) were scaled from 10 CFR 61 analyses and added to the dose calculations. There was insignificant additional dose due to these additional nuclides.

ArPriuae Continuous air particulate samples were collected from five locations on a weekly basis. The five locations were separated into three groups:

Group I represents locations within the PBAPS site boundary (1 B, IZ and 1C), Group II represents the location at an intermediate distance from the PBAPS site (3A),

and Group III represents the control location at a remote distance from PBAPS (5H2). The following analyses were performed.

Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Tables C-V.1 and C-V.2 and Figures C-5 and C-6, Appendix C).

Detectable gross beta activity was observed at all locations.

Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of PBAPS.

The results from the On-Site locations (Group I) ranged from <6 to 34 E-3 pCilm3, with a mean of 17 E-3 pCi/m 3. The results from the Intermediate Distance location (Group II) ranged from <7 to 38 E-3 pCilm3 with a mean of 16 E-3 pCi/m3. The results from the Distant location (Group III) ranged from <7 to 35 E-3 pCi/m3 with a mean of 16 E-3 pCi/m 3 A comparison of the weekly mean values for 2005 indicate no notable differences among the three groups (Figure C-5, Appendix C).

In addition, a comparison of the 2005 air particulate data with previous years data indicate no effects from the operation of PBAPS (Figure C-4, Appendix C).

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nudides (Table C-V.3, Appendix C). Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. These values ranged from 37 to 73 E-3 pCi/m 3. All other nuclides were less than the MDC.

b.

Airborne Iodine Continuous air samples were collected from five locations (1 B, 1Z, 1C, 3A, and 5H2) and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). All results were less than the MDC.

Terrestrial

a.

MiEl Samples were collected from six locations (A(T), J, 0, R, and S) biweekly April through November and monthly December through March. Samples from six additional locations (B, C, D, E, L, P) were taken quarterly. The following analyses were performed.

Iodine-1 31 Milk samples from all locations were analyzed for concentrations of 1-131 (Tables C-VII.1, Appendix C).

All results were less than the MDC.

Gamma Spectrometry Each milk sample from locations A(T), J, 0, R, and S was analyzed for concentrations of gamma emitting nuclides (Table C-VII.2, Appendix C).

Naturally occurring K-40 was found in all samples and ranged from 1,090 to 1,640 pCi/l. All other nudides were less than the MDC. Comparison of the 2005 Cs-137 milk data with previous years data indicate no effects from the operation of PBAPS (Figure C-7 (Appendix C).

b.

FodPout Gamma Spectrometry Each food product sample from locations 1Q, 28 and 55 was analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C).

Naturally occurring Be-7 and K-40 activity was found at all locations.

Beryllium-7 activity was found in eight of nine samples and ranged from <220 to 1,190 pCi/kg wet Potassium-40 activity was found in all samples and ranged from 3,840 to 9,290 pCi/kg wet. All other nuclides were less than the MDC.

C.

Ambient Gamma Radiation Ambient gamma radiation levels were measured using Panasonic 814 (CaSO4) thermoluminescent dosimeters.

Forty-seven TLD locations were established around the site. Results of TLD measurements are listed in Tables C-IX.1 through C-IX.3 and Figure C-7, Appendix C.

All TLD measurements were below 10 mR per standard month, with a range of 4.1 to 8.8 mR per standard month. A comparison of the Site Boundary and Intermediate Distance data to the Control locations data indicate that the ambient gamma radiation levels from the Control locations 16, 18, 19 and 24 were essentially the same as the other locations. The historical ambient gamma radiation data from the Control locations was plotted along with similar data from the Site and the Intermediate Distance locations (Figure C-7, Appendix C)

D.

Independent Spent Fuel Storage Installation (ISFSI)

The Independent Spent Fuel Storage Installation (ISFSI) was utilized beginning June 2000. As of 2005, a total of 28 TN-68 casks, each loaded with 68 fuel bundles were in place on the ISFSI pad. As part of the overall REMP, additional TLDs were placed at locations near the site boundary and at the nearest resident. Although there was a general trend for increased dose at all REMP locations (see Figure C-7, Appendix C), Onsite location 1R, which is located on the hillside overlooking the ISFSI showed an increase trend of 0.5 to 1 mR per standard month when compared to controls (Figure C-8, Appendix C).

Location 2B, which represents the nearest residence showed no increase in dose rates when compared to controls. Data from location 2B is used to demonstrate compliance to both 40CFR1 90 and 1 OCFR72.104 limits.

E.

Land Use Census A Land Use Survey conducted during the 2005 growing season around the Peach Bottom Atomic Power Station (PBAPS) was performed by Normandeau Associates, Inc., NAI Environmental Services Division for Exelon Nuclear to comply with Section 3.8.E.2 of PBAPS's Offsite Dose Calculation Manual Specifications (ODCMS) and Bases. The purpose of the survey was to document the nearest milk producing animal in each of the sixteen meteorological sectors out to five miles.

In addition, the nearest residence and garden of >500 square feet were documented. The distance and direction of all locations were positioned using Global Positioning System (GPS) technology. The control milk farm (A) went out of business and a new control farm T was added to the PBAPS REMP. The results of this survey are summarized below.

Summary of Results - Inter-Laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, food products and water matrices for 19 analytes (Appendix E). The PE samples, supplied by Analytics Inc., Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:

1.

Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of laboratory results and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.

2.

ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

3.

DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag =

"A"), Acceptable with Warning (flag = "W'), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value.

Performance is acceptable with warning when a mean result falls in the range from +/-20% to +/-30% of the reference value (i.e., 20% <

bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

For the primary laboratory, 18 out of 19 analytes met the specified acceptance criteria. One sample did not meet the specified acceptance criteria for the following reason:

1.

Teledyne Brown Engineering's Analytics' September 2005 air particulate Fe-59 ratio of 1.35 exceeded the upper control limit of 1.30 due to a new technician not counting the air particulate in a petri dish.

For the secondary laboratory, 19 out of 23 analytes met the specified acceptance criteria. Four samples did not meet the specified acceptance criteria for the following reasons:

1.

Environmental Inc.'s ERA's November 2005 water Gross Alpha result of 41.1 pCi/L exceeded the upper control limit of 33.4 pCi/L.

This was due to using an Am-241 efficiency instead of a Th-232 efficiency when counting the sample. Using the correct efficiency gave a result of 27.0 pCi/L.

2.

Environmental Inc.'s ERA's November 2005 water Ra-228 result of 5.5 pCi/L exceeded the upper control limit of 5.0 pCi/L due to presence of radium daughters. Delay in counting 100 minutes gave a result of 4.01 pci/L.

3.

Environmental Inc.'s MAPEP's January 2005 air particulate Sr-90 result of 2.2 exceeded the upper control limit of 1.76 Bq/kg.

Reanalysis result was 1.56 Bq/kg.

4.

Environmental Inc.'s MAPEP's July 2005 soil Am-241 result of 48.4 exceeded the lower control limit of 56.77 Bq/kg due to incorrect sample weight being used in the calculation. When recalculated with the correct sample weight, the result was 97.0 Bq/kg.

The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

APPENDIX D DATA TABLES AND FIGURES COMPARISON LABORATORY

The following section contains data and figures illustrating the analyses performed by the QC laboratory, Environmental, Inc. Duplicate samples were obtained from several locations and media and split between the primary laboratory, Teledyne Brown Engineering (TBE) and the QC laboratory. Comparison of the results for most media were within expected ranges.

The QC laboratory results for gross beta insoluble and soluble in drinking water samples were very similar to those reported by the Primary laboratory. All results between the laboratories were within 4 pCi/I of each other. The data reported were well within the historical range.

" Results obtained by Environmental, Inc., Midwest Laboratory as a participant in the crosscheck program for proficiency testing in drinking water conducted by Environmental Resources Associates (ERA).

b Unless otherwise indicated, the laboratory result is given as the mean +/- standard deviation for three determinations.

c Results are presented as the known values, expected laboratory precision (1 sigma, 1 determination) and control limits as provided by ERA.

dThe original samples were calculated using an Am-241 efficiency. The samples were spiked with Th-232. Samples were recounted and calculated using the Th-232 efficiency. Results of the recount: 27.01 1 2.35 pCi/L.

Decay of short-lived radium daughters contributed to a higher counting rate. Delay of counting for 100 minutes provided better results.

The reported result was the average of the first cycle of 100 minutes, the average of the second cycle counts was 4.01 pCi/L E-8
