SUMMARY

Radiological characterization of background reference areas is the subject of this Terrestrial Background Study (TBS). Background reference areas were characterized to determine the background radionuclide concentrations allowing a comparison to results of samples collected at locations potentially impacted by past operations at the West Valley Demonstration Project (WVDP).

Two background reference areas ~ere selected to represent sand and gravel near surface geology and an area of Lavery till near surface geology. These two different surface geologies are present at WVDP. The geology on the north plateau is typically sand and gravel. The geology on the South Plateau is typically Lavery till.

Characterization was performed in accordance with the Field Sampling Plan (FSP) for Task Order 5, West Valley Demonstration Project Environmental Characterization Services (SEC 2012). Each background reference area was characterized by performing gamma walkover surveys (GWSs), collecting soil samples with a hand auger and with a geoprobe, scanning collected soil cores for gamma radiation, performing down-hole gamma logging in some cases, and performing a civil survey to record the sampling locations. The results of this characterization are provided in this TBS.

1.0 INTRODUCTION

This introductory section contains a site description, project description, and objectives.

1.1 Site Description The West Valley Demonstration Project (WVDP) (established to implement the WVDP Act) is located on approximately 152 acres within the 3,345-acre Western New York Nuclear Service Center (WNYNSC), owned by the New York State Energy Research and Development Authority (NYSERDA) in rural Cattaraugus County, *about 35 miles south of Buffalo, New York. The WVDP site is complex, involving a large number of potential radionuclides of concern and a variety of historical processes and events that are known to have or may have released contaminants into the environment. Known affected environmental media include surface soils, subsurface soils, groundwater, surface water, and sediments. The decommissioning of the WVDP site will involve a sequential set of activities that will vary significantly depending on the exact location and activity purpose.

WVDP is a unique operation within the U.S. Department of Energy (DOE). The West Valley Demonstration Project Act of* I 980 directed the Secretary of Energy to unde1iake five major activities, as follows:

• Solidify the liquid high-level waste (HL W) stored at WNYNSC into a form suitable for transportation and disposal (completed);

• Develop containers for the ~olidified HL W suitable for permanent disposal of the HL W (completed);

• Transport the waste to a federal repository for disposal (pending);

• Dispose of low-level radioactive waste (LLRW) and transuranic (TRU) waste produced by the Project (in progress); and

• Decontaminate and decommission the HL W storage tanks (PUREX and THO REX HL W tanks deactivated, July 2003), the HL W solidification facilities (in progress), and any material and hardware used in connection with the Project (in progress).

Decommissioning of the site will occur in two phases. Phase I of the decommissioning will entail removal of the Main Plant Process Building, the Low-Level Waste Treatment Facility, and certain other facilities within the WVDP area, which is known as the project premises. These activities will clean up much of the project premises to standards that will not prejudice decisions on the approach for Phase 2, which will complete the decommissioning. The Phase 2 decision shall be made within 10 years of the Record of Decision and Findings Statement documenting the Phase 1 decisions. Phase 2 actions will complete the decommissioning or long-term management of those facilities remaining at WVDP and WNYNSC following the completion of Phase 1 decommissioning.

Characterization of WVDP premises during and after Phase 1 decommissioning work is performed according to the Characterization Sampling and Analysis Plan (CSAP) (DOE 201 la).

Characterization will be performed by Safety and Ecology Corporation (SEC) under a Task Order contract with DOE. As DOE identifies needed characterization work, Task Orders are issued to SEC with defined work scope.

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (TOS) - Rev. 1 1.2 Project Description This Terrestrial Background Study (TBS) has been prepared for two background reference areas.

Two background reference areas were used because of differences in near surface geology at WVDP. The two different geologies are sand and gravel and Lavery till.

The background reference areas will be used throughout the remedial efforts at WVDP. The overall plan for Phase 1 decommissioning is specified in the Phase 1 Decommissioning Plan for the West Valley Demonstration Project (Phase l DP) (DOE 2009). Refer to that document for a discussion of project history and contaminants. Characterization was performed according to specifications in the Field Sampling Plan (FSP) for Task Order 5 (SEC 2012).

• SEC mobilized the appropriate equipment and qualified personnel to perform the required data collection activities associated with the task. The FSP discusses the gamma walkover survey (GWS) methods, civil surveying, field instrumentation, soil sampling methods, sample chain of custody documentation, quality assurance (QA)/quality control (QC) procedures, laboratory analytical methods, and statistical data evaluation methods. This TBS discusses the results of the characterization effort.

1.3 Objective The objective of this effort was to characterize two background reference areas. The surveys required to meet the objective included GWSs and systematic surface and subsurface soil sampling. The soil samples were analyzed for the 18 radionuclides of interest (ROis) and the 12 potential radionuclides of interest (PROis) as described in the CSAP and listed in Table 1-1.

Also included in the table are the minimum volume of soil collected for each analysis and the analytical method used.

The objective of the GWS was to determine the background gamma radiation signal for future comparisons. The objective of soil sampling was to assess the average concentration of RO Is and PROis in the background. .

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (T05) - Rev. I 2.0 CHARACTERIZATION ACTIVITIES AND RESULTS Each background reference area was characterized by performing GWSs, collecting soil samples with a hand auger and with a geoprobe for samples deeper than 15 centimeters (cm), scanning

.collected soil cores for gamma radiation, performing down-hole gamma logging in some cases, and performing a civil survey to record the sampling locations.

Gamma radiation was measured at each sampling location with both the Field Instrument for Detection of Low-Energy Radiation (FIDLER) and Sodium Iodide (NaI) detector for 30 seconds each, 15 cm above the ground surface. The gross gamma measurements were made before soil samples were collected.

The soil cores were scanned for gross gamma radiation. Down-hole gamma logging was also performed.

• The work performed was specified m the FSP for Task Order 5 (SEC 2012) and briefly summarized in the following section.

2.1 Gamma Walkover Survey SEC performed a GWS of 100 percent of accessible surfaces of each background reference area with a FIDLER detector and a 2-inch diameter by 2-inch tall NaI detector.

The detectors were coupled to a Large Area GPS Gamma Survey System (LAGGSS) consisting of a Trimble Global Positioning Sy1item (GPS) unit coupled to the detector(s) and subsequently downloaded and plotted to provide a visual map and the relative gross gamma activity. The SEC LAGGSS system delivered multiple gross gamma results and coordinates per square meter of surface area. The raw data was processed into graphic depictions of gamma ray count contours.

The data was also used to compare the relative sensitivity of the NaI and FIDLER detectors to the mix of radionuclides present.

The walkovers were performed using the cart shown in Photograph 1 in Appendix A in large open areas of the site. Detectors on the cart were positioned no farther apart than 85 cm to assure the minimum data density of one measurement per square meter is not exceeded. A technician walked with the detector in other areas of the site where caii access was difficult or impractical.

The GWS recorded a survey measurement and a paired position approximately every second.

The GPS attains sub-meter accuracy (x, y data). Data were electronically logged and include coordinates in New York West State Plane feet (NAD83). The data contain counts per minute (cpm), northing and easting (x, y), position dilution of precision (PDOP), date, and time. The average walkover speed did not exceed 0.5 meters per second (m/s).

2.2 Soil Sampling.

Soil horizons are defined as "shallow surface,'; 0 - 15 cm below ground surface; "deep surface,"

15 - 100 cm below ground surface; "surface, 0 - 100 cm below ground surface; and "subsurface," 100 cm and deeper. Shallow surface soil samples to a depth of 15 cm below July 2014 2-1

IUNCONTROLLED DOCUlVIENT I Terrestrial Background Study (TBS) (T05) - Rev. I ground surface were collected using a 10-cm diameter hand auger. Samples deeper than 15 cm below ground surface were collected using direct-push drilling methods.

A sufficient volume of soil was collected allowing all 18 ROis and 12 PROis to be analyzed.

Sufficient volume was approximately 900 grams (g). By collecting surface soil samples from 10-cm diameter holes 15-cm deep and deeper soil samples from 5-cm diameter holes, a sufficient volume of media was collected.

Thirty-second static FIDLER counts and 30-second Nal detector counts were performed at a distance of 15 cm above the ground surface prior to acquiring samples. A physical description of the material sampled, date, and.time was included. Additionally, the location (coordinates) of the sample was recorded in NY State Plane West NAD83 with a quality of+/- a hundredth of a foot

[+/- 0.01 foot (ft)] for each sample.

Hand-auger samples were placed in stainless steel mixing .bowls and homogenized with a stainless steel trowel and packaged in plastic jars or glass vials (for tritium or carbon-14 analysis) as samples. The mixing bowls were placed on plastic sheeting to prevent sample cross-contamination.

Samples taken using direct push methods were collected in acetate liners. Once removed from the steel collection tube, the acetate liners were cut open and the sample was extracted and placed into a mixing bowl for homogenization and packaging. Sample collection was sometimes performed on a table covered with plastic sheeting. The typical sample collection approach was shown in Photograph 2 in Appendix A.

Sample tools and drilling equipment was wiped clean with masslin artd 409 cleaning solution as necessary to remove visible dirt. Tools were scanned for alpha and beta-gamma radiation and a swipe for radioactive contamination was collected. The swipe was counted in a low background counter. The sampling equipment was considered free of radioactive contamination provided results were less than the instrument lower critical level (Le) of approximately 1 cpm for alpha and 19 cpm for beta-gamma radiation. Surface and subsurface samples were scanned for gamma radiation before they were homogenized.

2.3 Radionuclide Concentrations m Background Soils Near the West Valley Demonstration Project Background soil data is discussed in Section 2.3 .1. Gamma walkover data is discussed in Section 2.3.2. Gamma radiation data taken 15 cm above each soil sampling location before sample collection scans of soil cores and down-hole data are discussed in Section 2.3 .3.

Data. used has been validated and more discussion of the validation results is presented in Section 3.3. All data was used in computations (e.g., means of data sets) unless it was rejected by the validator. This is discussed further in the Radiological Interferences Technical Memorandum (SEC 2013).

July 2014 2-2

IUNCONTROLLED DOCUlVIENT I Terrestrial Background Study (TBS) (TOS) - Rev. I 2.3.1 Background Soil Data from Background ~eference Areas There are three sources of background soil radionuclide concentrations discussed in this TBS.

The first is historical data compiled from 1991 through 2007 at the Great Valley soil sampling location. This sampling station is located approximately 30 kilometers (km) directly south of WVDP. In 2007, soil sampling was reduced to once every 5 years; therefore, the sample collected in 2007 is the last available sample (DOE 2011 b). This data, collected from 0 - 15 cm deep, is compiled and shown in Table 2-1. The original data set was provided in scientific notation and was not altered for presentation herein. The data shown is uncensored; values less than the detection level are reported and values less than the laboratory detector background are reported as are negative values.

The second and third sources are from data collected in July and August 2012 at two background*

reference areas within WNYNSC. The two background reference areas were chosen to represent differing surface geology found on the north versus the south plateaus of the WVDP site.

Background Reference Area 1, shown on Figure 2-1, was in the sand and gravel unit.

Background Reference Area 2, shown on Figure 2-2, was in a surface outcrop of Lavery till.

Both of these locations were evaluated using site historical soil sampling data collected at the WNYNSC air sampling station (FXVDR) at the intersection of Thornwood Drive (Highway 86) and Fox Valley Road. This intersection may be seen on Figure 2-2. Sample analytical data for strontium-90, cesium-137, americium-241, plutonium-238, and plutonium-239 were compared to the same radionuclide analytes at the Great Valley background station. A student t-test showed there was no reason to suspect that the means of the data sets for each radionuclide were different at the 95 percent confidence level (DOE 2012). These two background reference areas were selected on this basis and because both background reference areas are typically upwind of the WVDP site.

Each of the background r.eference areas was 2,000 m2 . Ten equally spaced locations representing 200 m2 each were sampled. Two samples were collected at each location. One was a 0 - 15 cm near surface sample and the other was a 15 - 100 cm deep surface sample. The analytical data from each background reference area is shown in Appendix B and summarized in Tables 2-2 and 2-3.

Naturally occurring radionuclides and anthropogenic radionuclides reasonably detectable in background soils from nuclear fallout were compared to potential on-site radionuclide contaminants using the 95 percent upper tolerance level (UTL). Other radionuclides were compared to three times their uncertainty in accordance with the CSAP (DOE 2011). Tables 2-2 and 2-3 reflect these different methods for comparing data collected in areas potentially impacted by WVDP site operations to background soil data.

The Wilcoxon Rank Sum Test was used to compare the mean concentrations of strontium-90, cesium-13 7, americium-241, plutonium-23 8, plutonium-239, uranium-232, uranium-233/234, uranium-235, and uranium-238 found at the Great Valley sampling station to the Background Reference Area 1 and Background Reference Area 2 near surface sample concentrations at the 95 percent confidence level. This comparison was performed as a further check as to whether the Background Reference Areas 1 and 2 were potentially impacted by past WVDP operations.

The results of these comparisons for the radionuclides are summarized in Table 2-4. If the entries indicate "yes," the null hypothesis was rejected or "no" if it was not. The entries in the table also indicate which background reference data set mean was greater than the other when the null hypothesis was rejected. "NA" in the table means that the radionuclide was not analyzed in both data sets that were compared.

The mean concentration for U-238, 0.78 pCi/g, at Background Reference Area 2, was greater than the mean U-238 concentration, 0.57 pCi/g, at the Great Valley location. These results, while statistically significant, are well within typical concentrations of naturally occurring uranium throughout the United States. Otherwise there was no reason to suspect that the mean concentration of any other radionuclide was greater at a background reference area than at Great Valley. This conclusion is an indicator that the background reference areas selected have not been impacted by WVDP operations.

Table 2-4 above shows a statistical difference between the mean concentrations of several of the different radionuclides between the two background reference areas. However, many of the individual sample results used to compute the mean and standard deviation of the data sets were less than the analytical minimum detectable concentration (MDC).

2.3.2 Gamma Walkover Data for Background Reference Areas The surface of each background reference area was surveyed I 00% with both the FIDLER and the Nal detector types. The number of data points collected, minimum, maximum, average, and July 2014 2-9

IUNCONTROLLED DOCUlVIENT I Terrestrial Background Study (TBS) (TOS) - Rev. I standard deviation for each detector type at each background reference area is shown in Table 2-5.

Dev. (cpm) 926 979 698 794 Shown on Figures 2-3 and 2-4 are side-by-side comparisons of the two detector types at each background reference area. FIDLER detectors are larger and more sensitive than NaI detectors, thus the higher overall count rates for the FIDLER detectors are expected. Also shown on Figures 2-3 and 2-4 are the locations where soil samples were collected.

Figures 2-5 through 2-8 are plots of the count rates versus frequency of occurrence. The data are clearly normally distributed as would be expected for background data sets.

A t-test was performed comparing the means of each detector type at the two background reference areas at the 95 percent confidence level. The t-test was appropriate because the sample sizes were large and the data was normally distributed as seen in Figures 2-5 through 2-8. The mean count rate with both detectors is higher at Background Reference Area 2 compared to Background Reference Area 1 with 95 percent confidence.

2.3.3 Gamma Measurements at References Areas Sampling Locations A 30-second gamma measurement was made with each detector type at.each location before soil samples were collected. These results, along with location information, are shown in Table 2-6.

The gamma signal was logged in each hole formed when the soil cores were extracted at the 10 sampling locations at each reference location. The FSP required this to be done at 15 cm increments from four sample locations drilled 1 m deep in Lavery till. All locations in Background Reference Area 2 (Lavery till) were logged in 15-cm increments, All locations at Background Reference Area 1. (sand and gravel) were logged in 30-cm increments. This field practice exceeded the FSP specifications. The results of the gamma logs at each sample location are provided in Appendix C. Lithologic logs are also provided in Appendix C.

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (T05) - Rev. I 3.0 QUALITY ASSURANCE QA information was collected for soil data and for the GWS data. Soil QA data is presented in Section 3 .1 and GWS QA data is presented in Section 3 .2. Data verification and. validation information is presented in Section 3 .3.

3.1 Soil Sample Quality Assurance The characteristics of precision, accuracy, representativeness, completeness, and comparability are discussed in Sections 3.1.1 through 3.1.5, respectively.

3.1.1 Precision Precision is a measure of the degree to which two or more measurements are in agreement.

Precision in the laboratory results was assessed through the calculation of relative percent differences (RPDs) for the replicate laboratory control samples (LCSs) and laboratory control sample duplicates (LCSDs). Precision was also evaluated for field duplicate sample analyses.

According to the CSAP, precision reflects measurement variability as observed in repeated measurements of the same subsample; for radio-analytical methods, the required precision is reflected by required method detection limits (DOE 201 la). In other words, specifying the required detection limits is equivalent to specifying the required method precision; therefore, specific tolerance limits for precision were not set in the FSP. The results of precision evaluations are simply reported.

Field duplicates are the least precise because they introduce all sample uncertainty from field sample collection through laboratory analysis. Field duplicates are collected as sample splits from the same sample mass. Two samples were extracted after homogenization with hand tools.

These two samples were sent separately for laboratory analysis and the results were compared to establish a measure of precision.

The RPD calculation allows for the comparison of two analysis values in terms of precision with no estimate of accuracy. RPD is calculated as:

.RPD = ( m ~M) x 100 Where:

m = First measurement value, M = Second measurement value, and M =Mean value ofM and m.

LCS and LCSD samples were analyzed for the following:

• Americium-241 by alpha spectroscopy arid gamma spectroscopy,

• Carbon-14 by liquid scintillation,

• Cobalt-60 by gamma spectroscopy, July 2014 3-1

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (TOS) - Rev.1

• Cesium-13 7 by gamma spectroscopy,

• Tritium by liquid scintillation,

• Neptunium-237 by alpha spectroscopy,

• Plutonium-239/240 by alpha spectroscopy,

• Strontium-90 by chemical extraction and gross beta analysis,

• Technetium-99 by chemical extraction and liquid scintillation,

• Uranium-232 by alpha spectroscopy, and

• Uranium-238 by alpha spectroscopy. .

The LCS and LCSD RPD for gamma spectroscopy were all performed using a calibration check source with 40,000 to 70,000 disintegrations per minute (dpm) in the radionuclide-specific energy channel for the spectrometer. While this is a measure of precision, this amount of radioactivity (dpm) is significantly higher than the amounts measured in the actual samples. The LCS and LCSD RPD for liquid scintillation, alpha spectroscopy, and gross beta analysis were calculated at concentrations that were representative of the soil clean-up goals.

There were 23 LCS and LCSO data pairs that were evaluated. In 74 percent of the data pairs, the RPD was 10 percent or less. Analyses for tritium, carbon-14, technetium-99, americium-241, and plutonium 239/240 each had at least one RPD result greater than 10 percent.

The Normalized Absolute Difference (DER) between the LCS and LCSD is used to determine that the results do not differ significantly (at the 99 percent confidence interval) when compar-ed to their respective combined standard uncertainty. A DER of less than or equal to three is considered acceptable.

DER= ---====JS=-=D==J==

J(csus )2 +(csuD)2 Where:

s LCS result D Duplicate result CS Us Combined Standard Uncertainty of the LCS CSUn Combined Standard Uncertainty of the duplicate Ninety-three percent of the DER calculations for the LCS and LCSD were three or less.

Precision for the field duplicates was calculated for cases when both samples analyzed for the same analyte had results greater than the minimum detectable activity (MDA) for each background reference area. This evaluation was performed for cesium-137, uranium-233/234, uranium-238, radium-226, radium-228, and thorium-232 (which is the same as for radium-228).

The results are shown in Table 3-1.

The RPD and coefficient of variation (CV) for uranium-233/234 and uranium-238 exceeded 10 percent; otherwise, the results are acceptable. These differences sometimes occur in field duplicates when the analytical results are small.

The accuracy requirement for off-site laboratory analyses set in the CSAP is a relative standard error of I 0 percent, as measured at the cleanup goal value, after correcting for precision.

Analytical accuracy is expressed as the percent recovery of an analyte that has been added to the control samples at a known concentration prior to analysis or duplicate analysis of a gamma spectroscopy standard with a known amount of radioactivity.

The accuracy of data was summarized in terms of relative error (RE). This calculation reflects the degree to which the measured value agrees with the actual value, in terms of percent of the actual value. RE is calculated as: *

% RE = Measured Value ~ Actual Value x 100 Actual Value Table 3-2 shows the results of accuracy determinations for LCS and LCSD samples.

3.1.3 Representativeness

There is no formal quantitative requirement for representativeness; representativeness is monitored by ensuring that sampling and analytical protocols are, in fact, carried out during field and laboratory work and that the quantity of data collected is sufficient to allow decision-making with the necessary level of confidence.

The data were collected in accordance with the FSP and the standard operating procedures (SOPs) contained in the FSP and the supporting plans and procedures. The data are considered representative of the field conditions and locations where they were collected.

3.1.4 Completeness Completeness is a measure Of the degree to which the amount of sample data collected meets the scope and a measure of the relative number of analytical data points that meet the acceptance criteria, including accuracy, precision, and any other criteria required by the specific analytical

. method used. Completeness is defined as a comparison of the actual numbers of valid data points and expected numbers of points expressed as a percentage. The data completeness goal for the CSAP is 80 percent, consistent with the Phase 1 Final Status Survey Plan* (FSSP).

Completeness is calculated after the QC data: have been evaluated, and the results applied to the measurement data. In addition to results identified as being outside of the QC limits established for the method, broken or spilled samples, or samples that could not be analyzed for any other reason, are included in the assessment of completeness. The percent of valid results is reported as completeness. The completeness will be calculated as follows:

T-(I+NC)

Completeness(%)= x 100 T

Where:

T Total number of expected measurements for a method and matrix, I = Number of invalidated results for a method and matrix, and July 2014 3-4

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (T05) - Rev.1 NC Number of results n.ot collected (e.g., bottles broken, etc.) for a method and a matrix.

Table 3-3 shows that the 80 percent completeness goal was met except for iodine-129 and protactinium-231. These were the data sets where all the data were rejected. Reasons for this are discussed in the Radiological Interferences Technical Memorandum (SEC 2013).

Comparability is a qualitative parameter expressing the confidence with which one data set can be compared with another. The comparability of the data, a relative measure, is influenced by sampling and analytical procedures. The data was collected with the specific protocols in the FSP. The collection methods were in accordance with the CSAP; therefore, this data set and future data sets should be comparable regardless of who obtains the sample or performs the analysis.

3.2 Gamma Walkover Quality Assurance GWS QA includes the following:

• Each detector was calibrated according to procedure SEC-RP-08, Workplace Monitoring.

• Instruments were set-up and checked according to procedure SEC-RP-52, Set-up and Operability Tests for Portable Field Instruments. This establishes reference readings and a

+/-20 percent acceptance range.

July 2014 3-5

IUNCONTROLLED DOCUIVIENT I Terrestrial Background Study (TBS) (TOS) - Rev.1

• Instruments were checked with a source of known radioactivity and for background according to procedure SEC-RP-53, Operability Tests - Field Instruments. Instruments all passed the specification that source and background checks fall within +/-20 percent of their original set-up readings.

• A 30-second measurement was made each day before use and at the end of the day at a reference location as specified in the FSP. Control charts were generated and an example is provided in Appendix D.

In addition to the measures listed above, each different. detector was to be used to survey a 1OO-m2 area established in Background Reference Area 1. The purpose was to allow measurements made by different detectors of the same type (FIDLER or NaI) to be normalized, if needed. A tarp was then placed over the area to attain, over time, and maintain stable soil moisture content. Soil moisture may have an impact on the detector response. It is expected that the moisture content will equilibrate over the course of several weather seasons.

When the survey of the 1OO-m2 area was performed, two FIDLER and two NaI detectors were used. The number of measurements, minimum, maximum, average, and standard deviation for each detector at the 1OO-m 2 test plot are shown in Table 3-4. Now that the 1OO-m2 plot on Background Reference Area I has been established, future site survey work can begin with the survey of this plot.

The two FIDLER detectors exhibited a 552 cpm difference in the mean response. The NaI detectors exhibited a 709 cpm difference in. the mean response. A way to normalize the detector response would have been to add 276 cpm to the response of one FIDLER and subtract 276 cpm from the response of the other FIDLER. Similarly, 355 cpm could be added to the response of one Nal detector and 354 cpm could be subtracted from the response of the other Nal detector.

Such normalization would affect the response of the detectors by less than 5 percent. This would have virtually no impact in the GWS data interpretation. The gamma radiation contours shown in Figures 2-1 and 2-2 are +/-2,000 cpm. Because the results of the two detector pairs shown in Table 3-3 is considered typical, normalization of detector response would not have added value to the way the data was interpreted. The differences in the detector response are considered July 2014 3-6

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (T05) - Rev.1 typical because detector crystals of the same media, size, and shape that are operated at their similar plateau voltages with photomultiplier tubes of a similar age will behave as the detectors shown in Table 3-4.

3.3 Data Verification and Validation Data verification was performed on 100% of the laboratory analytical data. Verification was performed to assure that samples sent for analysis were analyzed with results returned in hard copy and as an Electronic Data Deliverable (EDD). Verification of completeness of chain of custody records was performed. Verification that hard copy records from the laboratory matched the EDD was also completed. Errors found during verification were corrected.

Data deliverables meet U.S. Environmental Protection Agency (EPA) Level IV quality. Contract Laboratory Procedure (CLP)-like data packages were provided by the analytical laboratory to support independent third party validation. Ten percent of analyses were validated by an independent third party. The independent third party performed validation according to the US.

Department of Energy NNSA Service Center Model Data Validation Procedure (AQA 2010) and the applicable methods.

All data were used in computations (e.g., means of data sets) unless it was rejected by the validator. The data that was rejected is shown in Appendix B. Further discussion of data validation is provided in the Radiological Interferences Technical Memorandum (SEC 2013).

Reasons for rejected data were:

" Samples with a negative result with an absolute value greater than the MDC,

• fodine-129 results where there was significant interference from a gamma photo-peak from naturally occurring bismuth-212, and

• Samples where the chemical yield was less than 10 percent and with results less than the MDC.

IUNCONTROLLED DO~UMENT I Terrestrial Background Study (TBS) (T05) - Rev. 1 APPENDIXC

• Borehole Gamma Logs and Lithologic Logs July 2014

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (TOS) - Rev.I APPENDIXC Borehole Gamma Logs and Lithologic Logs The borehole gamma logs were performed using a Y:z-inch by I-inch Nal detector. The smaller detector was used so that it could fit into the borehole. Note that the smaller volume detector has a lower efficiency and a lower count rate response than the bigger NaI detectors used for the GWSs. Note also that the background count rate taken outside the borehole is less than that taken inside the borehole because inside the borehole the detector is surrounded by the source of gamma radiation signal.

The borehole gamma logs were handwritten while work was performed. The borehole gamma logs shown in this appendix were typed for this TBS. The signed original forms are on file.

IUNCONTROLLED DOCUMENT I Terrestrial Background Study (TBS) (TOS) - Rev. 1 APPENDIXD Detector Control Charts Example Source and Background Control Charts Example control charts for the FIDLER detector for source checks and background checks are shown here. Detectors are taken out of service if the source or background checks are not within the required tolerance of 20 percent. If a detector does not pass the morning daily check, the data from the previ0tis day is evaluated for use. The data is not used if erratic readings outside that previously collected for the area used are identified .

One FIDLER detector was taken out of service because it failed the background check above the upper tolerance . The detector was damaged and the failure was due to a light leak. The detector was not returned to service.
