3. DEFINITIONS/ACRONYMS NOTE ZS-LT-02, Characterization Survey Plan (Reference 6.6) provides a listing of common definitions associated with Characterization.

3.1.

a priori - the probability assigned to a parameter or to an event in advance of any empirical evidence, often subjectively or on the assumption of the principle of indifference.

3.2.

Background Radiation - Radiation from cosmic sources, naturally occurring radioactive material, including radon (except as decay product of source or special nuclear material),

and global fallout as it exists in the environment from the testing of nuclear explosive devices or from nuclear accidents which contribute to background radiation and are not under the control of the cognizant organization.

3.3.

Biased Measurements - Also referred to as judgmental measurements, biased measurements are performed at locations selected using professional judgment based on unusual appearance, location relative to known contamination areas, high potential for residual radioactivity, general supplemental information, etc.

3.4.

Characterization Survey - A type of survey that includes facility or site sampling, monitoring, and analysis activities to determine the extent and nature of contamination.

Characterization Surveys provide the basis for acquiring necessary technical information to develop, analyze, and select appropriate cleanup techniques.

3.5.

Data Quality Assessment (DQA) - The scientific and statistical evaluation of data to determine if the data are of the right type, quantity, and quality for the intended use.

3.6.

Data Quality Objectives (DQO) - Qualitative and quantitative statements derived from the DQO process that clarify study technical and quality objectives, define the appropriate type of data, and specify tolerable levels of potential decision errors that will be used as the basis for establishing the quality and quantity of data needed to support decisions.

3.7.

Derived Concentration Guideline Level (DCGL) - A derived, radionuclide-specific activity concentration within a survey unit corresponding to the release criterion (referred to as Base Case DCGLs). DCGLs are derived from activity/dose relationships through various exposure pathway scenarios. To ensure that the summation of dose from each source term is 25 mrem/yr or less after all FSS is completed, the Base Case DCGLs are reduced based on an expected, or a priori, fraction of the 25 mrem/yr dose limit from each source term. These reduced DCGLs are called Operational DCGLs. The Operational DCGL is then used as the DCGL for the FSS design of the survey unit (calculation of surrogate DCGLs, investigations levels, etc.).

3.8.

Direct Measurement - Radioactivity measurement obtained by placing a radiation detector near the surface or media being surveyed. An indication of the resulting radioactivity level is read out directly.

3.9.

Final Status Survey (FSS) - Measurements and sampling to describe the radiological 6 of 42

ZS-LT-100-001-001 Revision 2 Information Use conditions of a site, following completion of decontamination activities (if any) in preparation for release.

3.10. Historical Site Assessment (HSA) - A compilation of information prepared for use in planning the FSS of a survey unit. It summarizes the operational history, characterization, remedial action, or operational survey data, and other information, such as past burial or spill events, to help establish the FSS unit classification and the bases for the design of the FSS.

3.11. In-Situ Gamma Spectroscopy - A sample methodology used to discriminate among various radionuclides on a basis of characteristic energies at the sample location (in-situ).

The site has purchased units from Canberra named ISOCS (In-Situ Object Counting System) to perform this analysis.

3.12. Minimum Detectable Concentration (MDC) - The Minimum Detectable Concentration (MDC) is defined as the a priori activity level that a specific instrument and technique can be expected to detect 95% of the time. When stating the detection capability of an instrument, this value should be used. The MDC is the detection limit, (LD), multiplied by an appropriate conversion factor to give units of activity. The critical level, (LC), is the lower bound on the 95% detection interval defined for LD and is the level at which there is a 5% chance of calling a background value greater than background.

3.13. Minimum Detectable Count Rate (MDCR) - the a priori minimum count rate that a specific instrument and technique can be expected to detect 95% of the time.

3.14. Sample Plan - Sample Plans are prepared for each survey unit independently and contain, at a minimum, survey instructions, the number and location of survey measurements and samples, survey maps, instrumentation requirements, and safety requirement as necessary.

3.15. Scanning - An evaluation technique performed by moving a detection device over a surface at a specified speed and distance above the surface to detect radiation.

3.16. Standard Deviation - The measure of the variability around the mean of a data set.

3.17. Subsurface Soil - Soil deeper than 15 cm below the ground surface.

3.18. Survey - A systematic evaluation and documentation of radiological measurements with a correctly calibrated instrument or instruments that meet the sensitivity required by the objective of the evaluation.

3.19. Survey Area - Survey areas are established based on logical physical boundaries and site landmarks for the purpose of documenting and conveying radiological information, and in order to facilitate the scheduling, management and reporting of Characterization data.

The survey areas may be sub-divided into one or more survey units.

3.20. Survey Package - Survey Packages are prepared for each survey area independently. A survey package is a collection of files that will contain all the quality records and other documents relevant to the Characterization of a survey unit. A Survey Package may contain one or more Sample Plans.

3.21. Survey Unit - A contiguous unit within a survey area of similar use history and the same classification of contamination potential.

4.1.2 When documenting survey information, all personnel shall ensure that all QA records are of good quality and legible. Legibility is determined to be readable and reproducible.

4.1.3 Scans should be conducted in areas likely to contain residual activity, based on the results of the Historical Site Assessment (HSA) (Reference 6.7), investigative surveys or operational survey records.

4.1.4 Judgmental measurements should be performed at locations of elevated direct radiation, as identified by surface scans, or at locations likely to contain elevated levels of residual radioactivity, such as but not limited to, in sewers, air ducts, storage tanks, septic systems and on building roofs.

4.1.5 Media sampling, including material such as concrete, paint, sludge and residue in drains or debris collected from locations likely to accumulate contamination (cracks in the floor, horizontal surfaces and drains) should be performed as necessary to determine depth and extent of contamination.

NOTE A combination of both scan measurements and media sampling is recommended to meet the objectives of a Characterization Survey for open land.

4.1.6 Characterization Surveys for surface and subsurface soils should employ techniques to determine the lateral and vertical extent of contamination and radionuclide concentrations in the soil.

4.1.7 If surface soil contamination is detected, then subsurface soil samples should also be collected at the same location.

4.1.8 Subsurface soil samples should be taken at locations where subsurface soil contamination is known or suspected (e.g., buried tanks, underground process lines, etc.).

4.1.9 For continuing Characterization, 10% of all media samples collected in a survey unit, with a minimum of one sample, will be analyzed for the full initial suite of radionuclides. The samples selected will be biased to those areas exhibiting the highest gamma activity. In addition, one additional sample beyond the 10%

minimum will be selected at random to be analyzed for the full initial suite of radionuclides.

9 of 42

ZS-LT-100-001-001 Revision 2 Information Use 4.1.10 For sample(s) with positive results for both a HTD ROC and the corresponding surrogate radionuclide (Cs-137 or Co-60), the HTD to surrogate ratio will be derived.

4.1.11 When characterizing penetrations in structures, perform a scan of the accessible surfaces, and acquire a direct measurement from the highest count rate location within the penetration.

At the minimum, the instruments and detectors selected for direct measurements and scanning should be capable of detecting the gross gamma, beta-gamma and/or alpha activity to a Minimum Detectable Concentration (MDC) of 50% of the applicable action level.

4.3. Prerequisites 4.3.1 Survey units should be cleared of all loose equipment and materials to the maximum extent possible.

4.3.2 Engineering and safety requirements that may be required prior to accessing an area or performing a survey activity include, but are not limited to the generation and approval of work packages, job safety analysis, lockout/tagout procedures, dig permits, confined space permits, and/or Radiation Work Permits (RWP).

4.3.3 Long-handled extension devices or appropriate staging/mechanical devices shall be used to safely access structural surfaces greater than 6 feet above a normal walking surface.

NOTES The vegetation should be cut as close to the ground surface as possible.

With the exception of accessibility, the use of an In Situ Object Counting System (ISOCS) for Characterization does not require vegetation to be removed.

4.3.4 To eliminate physical obstructions, open land survey units should be cleared of debris and/or vegetation to the extent possible.

4.3.5 All identified physical hazards in the survey unit shall be either removed or marked as appropriate.

4.3.6 Prior to performing Characterization, a reference coordinate or grid will be established in all open land or structural survey units that will be subjected to FSS.

Calculation of Static and Scan MDC Page 1 of 2 ZS-LT-100-001-001 Revision 2 Information Use MDC is the minimum activity concentration on a surface or within a material volume, that an instrument is expected to detect (e.g., activity expected to be detected with 95% confidence).

The MDC is dependent upon the counting time, geometry, sample size, detector efficiency and background count rate. For a portable instrument, MDC is calculated using two different methods depending on the mode of operation, static (MDCstatic) or scanning (MDCscan).

Total Efficiency Instrument efficiencies (i) are derived from the surface emission rate of the radioactive source(s) used during the instrument calibration. Total Efficiency (t) is calculated by multiplying the instrument efficiency (i) by the surface efficiency (s) commensurate with the radionuclides alpha or beta energy using the guidance provided in ISO 7503-1, Evaluation of surface contamination - Part 1: Beta-emitters (maximum beta energy greater than 0.15 MeV) and alpha-emitters (Reference 6.11).

Beta Scan Measurement MDC The formula used to determine the scanning MDC at the 95% confidence level is:

=

(60

)

()(

Where, MDCscan = Minimum Detectable Concentration in dpm/100 cm2 d

= index of sensitivity (1.38) i

= observation interval (seconds) bi

=

background counts per observation interval t

=

total efficiency p

= surveyor efficiency (0.5)

A

= detector area in cm2 (not to exceed 126 cm2)

The observation interval (i) is considered to be the amount of time required for the detector field of view to pass over the area of concern. This time depends upon the scan speed, the size of the source, and the fraction of the detectors sensitive area that passes over the source. The scan speed is based on one detector window width per second however; other scan speeds may be used. For the Ludlum Model 43-68 gas flow proportional detector, the window width is 8.8 cm resulting in a scan speed of ~3.5 inches per second. The floor monitor detector is the Ludlum Model 43-37 with a window width of 13.35 cm which results in a scan speed of 5.25 inches per second.

Gamma Scan MDC The gamma scan MDC is discussed in detail in TSD-2011-004, Ludlum Model 44-10 Detector Sensitivity (Reference 6.12). This Technical Support Document (TSD) examines the gamma sensitivity for 5.08 by 5.08 cm NaI detectors to several radionuclide mixtures of Co-60 and Cs-137 using sand (SiO2) as the soil base. The TSD derives the MDC for the radionuclide mixtures at various detector distances and scan speeds. The TSD model uses essentially the same geometry configuration as the model used in MARSSIM. TSD-2011-004 provides MDC values for the expected ZSRP soil mixture based on detector background condition, scan speed, soil depth (15 cm), soil density (1.6 g/cm3) and detector distance to the suspect surface.
