PURPOSE ZS-LT-I 00-001-001 Revision 1 Information Use The purpose of this procedure is to provide instructions for the development, implementation and review of characterization survey packages, plans and sampling instructions. Results of characterization surveys are used to generate remedial action plans, classify survey areas and support the design of Final Status Surveys (FSS).
1.2.
SCOPE This procedure implements the requirements of applicable U.S. Nuclear Regulatory Commission (NRC) regulations and guidance documents; specifically, NUREG-1757, Volume 2, Revision 1 "Consolidated Decommissioning Guidance - Characterization, Survey, and Determination of Radiological Criteria" (Reference 6.1), and NUREG-1575, "Multi-Agency Radiation Survey and Site Investigation Manual" (MARS SIM, Reference 6.2).
The current decommissioning approach for Zion Station Restoration Project (ZSRP) calls for the demolition and removal of all on-site buildings, structures, and components to a depth of at least three feet below grade. Characterizati<,.m efforts will focus on open land areas and structures that will be subjected to FSS.

- 3. DEFINITIONS/ACRONYMS NOTE ZS-LT-100-001-001 Revision 1 Information Use ZS-LT-02, "Characterization Survey Plan" (Reference 6.5) provides a listing of common definitions associated with characterization.
3.1.
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'.
3.2.
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.
3.3.
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.
. 3.4.
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.
3.5.
. 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.
3.6.
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.
3.7.
Subsurface Soil - Soil deeper than 15 cm below the ground surface.
3.8.
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.
3.9.
- 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.
3.10.
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.
3.11.
Survey Unit - A contiguous unit within a survey area of similar use history and the same classification of contamination potential.

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 land survey.
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.).

4.2. Limitations 4.2.1 Survey instrumentation and analytical laboratori equipment and procedures should be selected based on detection capabilities for the expected contaminants and their quantities. At the minimum, the instruments and detectors selected for*
direct measurements and scanning should be capable of detecting the gross gamina, beta-gamma and/or alpha activity to a Minimum Detectable Concentration (MDC) of 50% of the applicable action level.

NOTE If the survey unit is classified as Class 1, then random-based measurements and/or samples are not required to be taken unless specifically compelled by the survey objectives.
1.)
If the survey unit is classified as Class 2, then designate fifteen (15) random-based measurements and/or samples (n).
2.)
If the survey unit is classified as Class 3 structure, then designate thirteen (13) random-based measurements and/or samples (n).

.I Calculation of Static and Scan MDC Page 1 of2 ZS-L T-100-001-00 I Revision 1 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 (ci) are.derived from !he surface emission rate of the radioactive source(s) used during the instrument calibration. Total Efficiency (i>J is calculated by multiplying the instrument effieiency (ci) by the surface efficiency (cs) commensurate with the radionuclide's 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 6.8).
Beta Scan Measurement MDC The formula used to determine the scanning MDC at the 95% confidence level is:

Minimum Detectable Concentration in dpm/100 cm2 index of sensitivity ( 1.3 8) observation interval (seconds) background counts per observation interval total efficiency surveyor efficiency (0.5) detector area in cm2 (not to exceed 126 cm2)
The observation interval (i) is considered to be the amount of time required for ~he 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 detector's 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 6.9). This Technical Support Document (TSD) examines the gamma sensitivity for 5.08 by 5.08 cm Nal detectors to several radionuclide mixtures of Co-60 and Cs-137 using sand (Si02) 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 MARS SIM (Reference 6.2). 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.
