Saxton SMCM Survey FinalReport - Appendix A Survey Release Records Appendix A Survey Release Records

Sarton SMCMSurvey FinalReport - Appendix A Survey Release Records This appendix provides the results for each of the Survey Release Record (SRRs). Each batch of debris or soil was assigned an SRR report.

The reports include data for four nuclides: naturally occurring potassium (K-40); uranium (Bi-214); thorium (TI-208); and cesium (Cs-137). The results for the naturally occurring nuclides were reported as a convenience, and to permit comparison with the lab measurements.

Each report shares the same format. A data header block at the top of every report provides a general description of the survey including the Survey Location Code (SLC) assigned to the SRR, the equipment used, the date of the survey, the name of the surveyor, amount of material surveyed (in tons), the moisture content (in percent as determined by the laboratory), a derived dry density, a description of the material surveyed, and the date of the survey. The first table below the header block provides a summary of the analysis of the spectra taken, including the mean, median, maximum, minimum and two-sigma values for each of the four nuclides of interest (after a 5 acquisition moving average filter is applied). The data is reported as dry concentration.

Next the four-plot method, from exploratory data analysis (EDA), was applied to the Net Cs-137 values (after a 5 acquisition moving average filter is applied). The values are plotted in pCi/g and the alarm limit that was utilized is shown as a dashed line.

On the following page, a waterfall plot is utilized to show all the spectral data collected. Below the waterfall plot is a table summarizing the files recorded for the SRR.

If an alarm occurred during a survey, a few acquisitions or the entire belt was removed by GPU and placed in a separate "suspect" pile or barrel. The SRR reports only include data that was processed into the "clean" pile.

The calibration factors for KUT were calculated using a log-log extrapolation from the Cs-137 and Co-60 results (which were based on NIST traceable sources). This extrapolation is adequate for K-40, whose energy lies close to Co-60. However, the extrapolation has larger uncertainty for Bi-214 (uranium) and TI-208 (thorium). In addition, calculation of net uranium was derived from the 1764 keV photo peak from Bi-214. There are two main sources of background in the ROI at 1764 keV: Compton scatter from the Tl-208 peak at 2615 keV and Compton scatter from the Bi-214 peak at 2204 keV. The later was not removed from the gross counts in the ROI. This generated concentrations of uranium that were higher than the laboratory's.

During the course of surveying the debris pile, seasonal climatic conditions at Saxton changed from those characteristic of late winter to those of late spring. During a warm spell that occurred while processing SR-55 batch 25, the ambient conditions in the trailer supporting the electronics rose above 401C. The data acquisition computer shut down automatically. Following recovery from the event, the zero offset of the MCAs was found to have shifted downward. The computer controlled amplifier gain was adjusted to re-align the K-40 peak (1461 keV) of each MCA back to channel 250. Other peaks were shifted be varying amounts with greater shifts observed for energies farther away from 1461 keV. The event and its recovery is summarized in Appendix H.

Page A-I

Saxton SMCM Survey FinalReport - Appendr A Survey ReleaseRecords The system was re-aligned prior to starting the second material pile (SR-62 batches reported in this report). However, the data collected in SR-55 batches 25 to 38 reflect the shift.

The immediate assessment of the data indicated that the system had shifted by less than 20% in reported Cs-137 concentration, and the system was used as a process monitor for alarms without further change. For reporting the data, additional review indicated that Detectors I and 2 had experienced similar shifts in zero offset that were significantly greater that the shift experienced by Detectors 3 and 4. In order to report the data, SR-55 batches 25 to 38 make use of only Detectors 3 and 4. The impact of the shift resulted in the mean reported Cs-137 concentration changing from 0.04 pCi/g to -0.1 pCi/g for SR-55 batches 25 to 38.

Saxton SMCM Survey FinalReport -Appendix B 5x2 Detector CalibrationFactors Appendix B SRA Tech Note 03-003 Nal Detector Calibration Factors

Saxton SMCMSurvey FinalReport - Appendir B 5x2 Detector CalibrationFactors SRA Tech Note no.03-003 Dated 06-24-03 Author: R.E. Burmeister and R.E. Bums and J. Kelley Nal Detector Calibration Factors This document summarizes development of the calibration factors for the 5-inch x 2-inch (12.7 cm x 5.1 cm) sodium iodide (Nal) detectors used in the Subsurface Multi-Spectral Contamination Monitor (SMCM). The calibration factors provided herein were computed using results from a point kernel model of the SMCM detectors. The model was implemented using the QAD-SRA point kernel code in conjunction with the MONTE Monte Carlo source point generation utility.

This document provides a general description of the modeling process and shows how the results from the QAD-SRA model were converted to calibration factors for the SMCM detectors.

Calibration factors are given for a uniform source. Calibration factors were developed for primordial K-40, Cs-137, primordial U, primordial Th.

The calibration factors for the SMCM detectors depend on

the sensitivity measured for each detector (expressed in terms of net count rate per unit flux) for the photon energy of interest, and

the flux per unit activity for the source geometry of interest.

Detector Sensitivity:

The average sensitivity data measured for the four SMCM detectors deployed for the measurements made prior to deployment are given in Figure I-B and Figure 2-B. This data was acquired by determining the net photopeak count rate for each detector using NIST traceable sources of Cs-137 and Co-60 at a distance of one meter from the face of each detector. As seen in the figures, the flux is computed at a point corresponding to the center of the detector, giving a source-to-detector distance of 40.4 inches (102.54 cm). The flux at the detector point is computed assuming no air attenuation, which is a valid approximation for the high-energy photons being considered. The sensitivity values are provided in dimensions of counts-per-second (cps) per unit flux.

Sensitivit measurementsfor the 1173 keVCo-60 photopeakfor thefourSAfCM detectors.

For nuclides of interest for which traceable calibration sources were not available (namely primordial K-40, primordial U, primordial Th), sensitivities were established through log-log extrapolation. Primordial U refers to naturally occurring U-238. The IAEA region-of-interest is centered on the prominent peak at 1.764 MeV due to the decay of Bi-214, a daughter in the decay of U-238. Primordial Th refers to naturally occurring Th-232, and the IAEA region-of-interest is centered on the prominent peak at 2.614 MeV due to the decay of TI-208, a daughter of the decay of Th-232.

Table 1-B gives the average sensitivities determined from the regression.

The QAD-SRA model was used to compute the uncollided flux in the 5-by-2 Nal crystal from a rectangular, volumetric source 25 ft (7.6 m) in length, 32 inches (0.8 m) wide and 4 inches (0.1 m) deep. The source material was soil (SiO 2 plus moisture content) at a density of 1.6 g/cm3 . The QAD-SRA model for the SMCM detectors accurately accounted for the 450 lead collimator, the copper foil, steel enclosure, and sand shielding. The model was also used to develop the ratio of the flux in air to the flux in Nal for the SMCM detector geometry. These ratios are needed to convert the measured sensitivity data from flux in air basis to flux in Nal so they are consistent with the detector response results from the QAD-SRA model. Results for the volume source are given in Page B-2

Saxton SMCMSurvey FinalReport - Appendix C Nal Detector Quality Control Appendix C Nal Detector Quality Control

Saxton SMCM Survey FinalReport - AppendL C Na! Detector Quality Control Quality Control SMCM QC measurements, including SRCs and PBCs, were performed at the beginning and end of each day and at least every five hours throughout the day. The QC routine consisted of a MCA gain check and adjustment if necessary at the start of the day and calculation of the net count in the Cs-137 ROI. The gain was not adjusted just prior to subsequent SRCs or PBCs. For SRCs, sources were mounted to a removable SRCs fixture, which mounts to the detector enclosure. The SRC spectra were logged in the same fashion as normal survey data; using the SMCM software to log survey strips of data to the field computer with unique SRC filenames.

The SRC results for each detector are shown in figures Figure 1-C, Figure 2-C, Figure 3-C, and Figure 4-C for SR-55 and figures Figure 7, Figure 8, Figure 9, and Figure Ofor SR-62. SRC data was investigated for trending using the Shewart rules for control charts.

Detector I for both SR-55 and SR-62 shows a trend wherein the value jumps by about 20%

higher value. At about SRC number 48 during SR-62, it was found that when the process software was started and a SRC immediately performed the initial value on detector I was high due to a shorter livetime. This was remedied by starting the software, going to the alignment screen, clearing detector 1,and then returning to the operations screen. A new strip or a PBC then performed recorded with the correct livetime and the counts for the SRC became repeatable within -2.7% and +5.4% of the mean for the SRC 55 through 85 (the last SRC). This operational workaround allowed detector I to behave much like detectors 2, 3, and 4. When the livetime of detector 1 becomes less than desired the counts increase and may be the cause of higher counts recorded for detector I during the processing of a batch.

PBCs were performed in addition to the SRCs for additional quality assurance. PBCs were performed by randomly placing a point-like Cs-l 37 source on the moving conveyor as the SMCM software recorded a PBC survey strip. This was repeated 3 times for each PBC. The maximum net Cs-137 value for each of the three measurements was recorded. The mean and standard deviation of the three measurements are shown in Figure 5-C and Figure 6-C for SR-55 and Figure II and Figure 12 for SR-62. No qualifications were placed on the PBCs.

Saxton SMCMSurvey FinalReport - Appendix D Determinationof Cs, K, U, TStrippingCoefficients Appendix D SRA Tech Note 03-002 Determination of Cs., K, U., T Stripping Coefficients

Sarton SMCM Survey FinalReport - Appendix D Determinationof Cs, K U, TStripping Coefficients SRA Tech Note no.03-002 Dated 08-18-03 Author: J. Kelley Determination of Cs, K, U, and T, Stripping Coefficients During a SMCM survey, the spectra collected from each detector are usually between five and ten seconds long. Typical SMCM surveys collect thousands of acquisitions per survey area.

Conventional gamma ray spectroscopy analysis methods utilize peak search algorithms. The number of spectra collected, along with the statistical noise of each short duration spectra in SMCM surveys prevents the use of conventional analysis methods.

Alternatively, the count rate in channels around a specific energy can be integrated; each integration is termed a region of interest (ROI). Spectral interferences among K, U, and Th radiations occur due to the combined effects of full-energy-peak overlaps and gamma ray scattering in the source, in the transport path from source to detector, and as a result of partial absorption processes in the detector. There are standard methods to treat these interferences, and the traditional IAEA recommended method is applied. In this method, only the relative contributions from the Th source into the U and K denoted as a and , respectively, and the U contribution to K, denoted as y, were taken into account (IAEA 1979). The contributions are displayed symbolically in the following equations:

Th = Th - Thb U = U - Ub - aThc K = K - Kb - ThC - yUC where Kb, Ub, Thb are background count rates; K, U , Th are uncorrected count rates; Kc, UC, Th, are corrected count rates.

The stripping coefficients or stripping ratios are defined as the ratio of the number of counts due to a nuclide in other windows to the number of counts in the window for the nuclide. In order to calculate the coefficients, one must record spectra of varying concentrations of uranium and thorium. The ratios are usually determined from calibration pads, which are large concrete pads that are doped with uranium, thorium, and potassium sources. Assuming that the Compton distribution is primarily a function of the detector and not the source geometry, point sources could be used instead of pads. Exempt, non-NIST traceable, uranium and thorium sources were used to determine the stripping coefficients. The background count rate constants (due to mostly to muon interactions) were assumed to be zero.

Appendix E Radon Detector

Radon Detector Setup The SMCM platform utilized for the survey at Saxton included a radon detector to monitor the radon content in air. The radon detector consisted of an Eberline HP21OL lead shielded pancake GM probe, an electric air pump, and hardware and tubing to direct air to the open face of the detector. The detector was connected to a Ludlum Model 440-1, which provided high voltage, preamp, and amplifier. A CIO-CTR (counter) card in the SMCM process computer monitored the counts from the M440-1. Counts from the radon detector were recorded during each of the SMCM's acquisitions.

Calibration No calibration was performed. The data was used for qualitative observations only.

Data Analysis The counts from the radon detector where accumulated for five seconds and logged. The raw radon data did not go through any changes (filters, moving average, etc.) prior to data analysis. Correlation plots ofthe radon and net Cs-137 data were used to confirm that variations in radon did not affect the survey data. Figure E-l shows the NAVSD Cs-137 net cps for each individual Nal detector versus the gross cps from the radon detector.

Sarlon SMCM Survey FinalReport, Appendix 0 Shift in Zero Offset Appendix G Shift in Zero Offset

Saxon SMCMSurvey FinalReport, Appendix G Shift in Zero Offset Statement of the Event The conveyorized SMCM was installed at Saxton and first operated in production mode on March 12th, 2003. On April 16th, 2003, during the processing of SR-55 batch 25, truck 12, high temperatures in the mobile control center (MCC) trailer that supports the electronics caused the shutdown of the process computer. Truck 12 was the last truck of the day and processing stopped about halfway through the loading of the truck. Truck 12 was dumped back into the feed pile. After the condition was studied and addressed, changes were noted in the system response. Detector 2 was found to have one outlier outside three standard deviations after taking the end-of-day source check. The window used for monitoring Cs-137 (centered about 662 keV) had lowered count rates. A single point above 3 standard deviations indicates that the system has changed. The source check utilizes a fixture for a source, ensuring constant location, and is counted for a long count time. It is measured with good precision, as indicated by the relative standard deviation of 1.5%. The exception noted was within 5% of the nominal value, and more than a factor of four less than ANSI N323 criteria. This exceptions report discusses this issue.

Nature of the Event The elevated temperatures resulted in the industrial computer shutdown, likely due to the internal thermistor over-temperature protection circuit. The industrial rating is typically negative 50 C to 500 C (230 F to 122 0 F) for operating, and -25 0C to 60'C (-13 0 F to 140 0F) for storage. The process computer has an internal heat shutdown setting that may be set to 400, 500 or 60'C (1040, 1220 or 1400F). The operating temperature range for the ORTEC MicroAce card is specified at 15'C to 30 0 C (30'F to 860 F). Temperatures in the rack-mounted enclosure exceeded the safety limit of 40'C (1220 F). The industrial computer serves as the host for the ISA card based ORTEC Micro Ace MCA. The rack-mounted enclosure temperature was likely higher than the ambient trailer temperature of 32 0 C (90 0 F).

As shown below, the data indicated no change up to the moment the computer was shut down by the thermal protection circuit. When the computer is shut down, cooling fans are turned off, which prevents the removal of stored heat. The data indicates that a change occurred after shutdown. It is likely the change resulted from slightly higher temperatures present during shutdown.

Detector 2 was three standard deviations low in the SRC in which a known source of Cs-137 is counted in a fixed location, and the count rate in a window centered on the peak is compared to prior operating history. The process computer system was temperature stabilized during the early spring months using a heater in the MCC trailer. Warmer temperatures are now present, and additional ventilation or cooling should be provided.

Page G-1

Sarton SMCM Survey FinalReport, Appendix G Shift in Zero Offset Prior to the event, the PBCs showed a standard deviation of about 1.5%, and three standard deviations of about 4.5%. The last PBC for Detector 2 was a little over three standard deviations (4.5%) indicating a change had occurred. When examined, the spectra showed that the peaks at 1461 keV (K-40) were in similar channels for all detectors (channel 250 out of 512 total channels), but the peak at 662 keV (Cs-]37) was slightly lower for Detector 2 than for the other detectors. The K-40 peak was routinely adjusted to maintain channel 250 by the computer-controlled fine gain setting. After the event, the gain was increased by 5% to keep K40 in channel 250. Increasing the gain (without also adjusting the zero offset) in this manner spreads the spectrum out. Thus, the thorium window (centered on Tl-208 at 2615 keV) is shifted to the right (higher apparent energy) while the Cs-137 window (centered on 662 keV) is shifted to the left (lower apparent energy). The shift of Cs-137 in Detector 2 indicates that a slight shift in the zero threshold (channel corresponding to 0 keV) has occurred. This is likely the cause of the (less than 5%) shift in the SRC data.

The MCAs had the zero offset (an internal trim pot) of the internal amplifier adjusted in accordance with vendor procedures just prior to calibration and deployment. To correct the (presumed) temperature-induced shift in zero offset would require repeat of the vendor procedure. Because the change is less than 20%, the vendor suggests that the operations continue. The standard deviations of the detector (that from the acceptance criteria) were small during operations in which the MCC trailer temperature was controlled (cold outdoor ambient temperatures). As the season changed and warmer temperatures were encountered, the MCC trailer temperature was no longer controlled.

The control chart alerted the system's operator to that fact. The less than 20% change (actually less than 5%) did not invalidate the results from monitoring material prior to the shutdown. The last ten tons present in the last truck (approximately ten minutes of data) was returned to the pile to be counted again. Further, investigation showed Detector I was also affected with a mean count rate lower by 5%. Detectors 3 and 4 showed no change.

The change in the net signal of detectors 1 and 2 dropping by 5%, which averages the four detectors, would be just over 2.5% if Cs-137 were present. The average for SR-55 batches 2 thru 24 showed an average of 0.6 pCi/g. SR-55 batch 26 shows an average of negative 0.3 pCi/g. The change from 0.6 to -0.3 is due primarily to the shifting of the Bi-214 peak at 609 keV out ofthe monitored Cs-137 window. Therefore, the apparent background had been lowered in the Cs-137 window. This change was due to the gain shift, and not the presence of Cs-137. These changes are well below the monitoring alarm limit for the system.

Furthermore, analysis of the spectrum using the components method showed no Cs-137 present. Examination of the components for Detectors I and 2 showed an apparent gain shift in the lower and upper ends of the spectrum in the second component (peaks in the first component are seen with a bimodal peak). Detectors 3 and 4 showed no gain shift.

This was consistent with the observations discussed above. Moreover, none of the Page G-2

Sarton SMCM Survey FinalReport, Appendix G Shifit in Zero Offset components showed evidence of a peak consistent with Cs-137. Thus, although there was a gain shift, there was no Cs-137 underlying the data that was missed by the system.

The system continued to operate as-is taking the penalty for a 2.5% lower Cs detection level.

Additional external cooling fans for the back of the rack as well as a roof-mounted air-conditioner were implemented.

The system was re-tuned when the system was broken down to move to the next location on-site. Re-tuning involved adjusting the zero offset and the system course gain using a pulse of known magnitude at roughly 25% and 75% of full-scale pulse height. Upon system demobilization efficiency verification may be run using vendor prescribed procedures.

Saxton SACM Survey FinalReport, Appendix H ComparisonofSMCM Results with Laboratory-BasedMeasurements SRA Tech Note no.03-001 Dated 06/24/03 Author: J. J. Shonka Comparison of SMCM Results with Laboratory-Based Measurements When results from two different measurement methods are compared, the reasons that differences might occur must be understood. The magnitude of these differences is important when the reported values differ by an amount that would be significant when compared to the applicable limits. The magnitude of the differences can also be important when the two measurements do not agree within the uncertainties of each method. This latter issue can occur because the results differ, but more often occurs when the stated uncertainty does not include all sources of bias and error.

In situ measurements in support of D&D often have no positive results for contaminants of concern. Comparison with widely distributed primordial nuclides from potassium and the uranium and thorium primordial series provide a convenient means to assess the performance of the in situ measurement system against laboratory results.

In comparing the lab and field measurements, sources of bias, when small and largely offsetting, can often be ignored as a matter of convenience.

Laboratory measurements have good precision, and excellent control of measurement parameters including sample geometry. However, laboratory measurements are subject to sampling uncertainty that is typically estimated through assumptions that are not quantified. NUREG-1501 notes that spatial variability in primordial nuclides can triple the exposure rate in a small field. Differences between field and lab measurements can be due to inadequacy in the sampling program for the lab samples.

Static in situ gamma spectroscopy using germanium-based detectors has been studied and compared to lab measurements ("An In Situ Gamma-Ray Spectrometry Intercomparison" pending Environmental Measurements Laboratory publication in Health PhysicsJournal). In those comparisons, agreement to within a factor of 2 was found to be the limits of the state of the art. Agreement, at times, would fall outside of this range, but the reasonable conjectures for the disagreement were asserted, typically due to simplified assumptions made by one of the in sit measurement systems.

Static in situ measurements enjoy a large field of view that typically provides an extremely large effective sample. The large effective sample greatly reduces sampling errors at the measurement point. However, static measurements are subject to uncertainties due to the assumptions of source and inherent shielding that are made to quantify the detector response.

The SMCM provides a scanning in situ gamma spectroscopy measurement, which can provide greater insight (than a more limited static measurement program) for the spatial source Page H-l

Saxton SMCM Survey FinalReport,Appendir H Comparisonof SACM Results with Laboratory-BasedMeasurements distribution (for measured radioactivity). However, most of the same assumptions for source and shielding distributions (as made for static in sizu measurements) are necessary to quantify the results.

In comparing in sitet field measurements with laboratory-based soil sample measurement made using gamma spectroscopy, the following parameters (beyond calibration bias and uncertainty) should be considered:

1. Percent Soil Moisture

2. Detector-Source Geometry

3. Source Distribution

4. Inherent Source Shielding

5. Sources and Treatment of Background

6. Degree of Secular Equilibrium and Branching Ratio Laboratory measurements report soil that has been dried. In situ measurements, by their very nature, measure wet soil. The difference provides a source for bias that should be considered in comparing lab and field measurements. The percent soil moisture typically varies from 10% to 20% by weight.

Lab measurements use well-defined detector source geometries (such as Marinelli Beakers) for which NIST traceable calibration standards are available. In contrast, field measurements use calibration to a NIST traceable point source with calculated response functions for assumed source geometries. Typical geometries used include semi-infinite source with collimated or uncollimated detectors. Other configurations include sources of limited extent for estimating response functions for DCGLemc or for conveyor based spectrometer systems. When the detector-source geometry does not match the assumed one, bias between the lab and field measurements can occur.

If the source distribution in the field is not uniform, laboratory assumptions for sampling are not met, and assumptions for field measurements to estimate response functions can introduce bias between field and lab results. In conveyor-based systems (which are finite in size and more sensitive to changes), these differences can be significant, particularly when an assumption of uniform concentration for the field of view of the detector is not met.

In field measurements, assumed source distribution includes aerial variability as well as changes with depth. Samples for lab measurements can improperly average with depth if great care is not taken in the sampling procedure. For field measurements, the inherent source shielding assumed for the detector can also result in bias in the reported results.

Lab results benefit from constant geometry measurements with well-characterized backgrounds.

Field measurements often have sources of background that cannot be fully shielded and which (if not considered) produce a bias that must be considered. For example, the monitored material on a conveyor system may not fully shield the radioactive material present in the ground under the Page H-2

Saxton SMCM Survey FinalReport, Appendix H Comparison of SMCM Results wit/h Laboratory-BasedMeasurements conveyor. One cannot simply take a "belt empty" background since the material in the belt will partially shield the ground.

The SRA Subsurface Multi-spectral Contamination Monitor (SMCM) reports primordial concentrations (potassium, uranium and thorium, KU&T) for specific in situ source geometries.

Example geometries include semi-infinite volume sources with shielded and unshielded detectors as well as specialized geometries such as conveyor systems. The measurements follow the practice of aerial surveys for KU&T. Potassium is monitored directly with the 1461 keV photon emitted in decay. Uranium and thorium are monitored using daughter products and the assumption of secular equilibrium. Bi-214 is used for uranium, and is monitored using the 1764 keV photon. T-208 is used for thorium, and is monitored using the 2614 keV photon.

The SMCM data analysis reports the primordial nuclides (potassium, uranium, and thorium) since these materials are present in virtually all environmental measurements. A comparison with laboratory measurements of soil samples is useful to identify any bias between the field measurements and those from a laboratory. This is particularly useful when the contaminants of concern (e.g.Cs-137) are not present at concentrations that can be measured using short duration measurements in field conditions. Others have used the comparison with potassium in comparing field measurements with lab results.

Figure 11-1 and Figure H-2 in this appendix and associated text were taken from the Human Health Fact Sheet ANL, July 2002: http://www.ead.anl.ov/Prub!doc/NaturalDecaySeries.pdf, and provide schematic presentations of the U-238 and Th-232 decay series.

Uranium and thorium occur in three natural decay series, headed by Uranium-238, Thorium-232, and Uranium-235, respectively. In nature, the radionuclides in these three series are approximately in a state of secular equilibrium, in which the activities of all radionuclides within each series are nearly equal. Potassium does not have an extended decay chain.

When gamma spectroscopy Lab based measurements are used, the daughter product Bi-214 is used for the uranium decay chain. To ensure equilibrium in lab measurements, best practice is to hermetically seal the sample in a crimp "tuna" can and permit two weeks of ingrowth to occur to ensure that Bi-214 is at equilibrium.

When the TI-208 radionuclide is used for assessing thorium content, the 36% branching ratio must be considered (see Figure 11-2).
