DQA Check Shed Design # EP CRT-7 Revision # Original Survey Unit # EP-CRT-7 Pmliminary Data Review' Answers to the foilowing questions should be fully documented in the Survey Unit Release Record Yes No N/A

1. Have surveys h e n performed in accordance with survey inshctions In the Survey Design? X

2. Is the instrumentation MDC for structure static measurements below the DCGLWfor Class Iand 2 X survey units, or below 0.5 D C G h for Class 3 sunrey units?

3. Is the Instrumentation M I X for embedded/buried piping M e measurements below the DCGLW7 X

4. W a s the instrumentationMM: for structure scan measurements, sol scan measurements, and ernbeddedlburied piping scan measurements bdow the DCGLh: or, if not was the need for additional X static measurements or soil samples addressed in the survey design?

5. Was the instrumentation ME for volumetric measurements and smear analysis c 10% DCGCw 7 X

6. Were the MDCs and assumptions used to develop them appropriate for the instruments and techniques used to performthe survey?

7. Were the survey methods used to collect data proper for the types of radiation involved and fw the media being surveyed?

X

8. WereUSpecialMethods' for data collection properly applied for the survey unit under r w l M X Q. Is the data set comprised of qualified measurement results collected in accordance with the suwey X design, which accurately refteds the radiologicaf status of the facil'rty?

Graphical Data Review

'I. Has a posting plat been created? X

2. Has n hls4ogram (or other frequency plot) been created? X

3. Have other graphical data tools been created to assist in analyzing the data? X Data Analysis I. Are all sample measurements betow the DCGLw (Class f & 2), or 0.5 DCGLw (Class 311 X

2. Is the mean of the sample data < DCGLw7 X

3. If elevated areas Rave been identied by scans andlor sampling, is the average activity in ~ c h X elevated area < D C G k (Uass I), < DCGLw (Class 2),or <0.5 OCGLw (Class 3)?

4. IstheresuRoftheElevatedMeasurmentsTest~1.0? X

5. Is the result of the statistical test (S+for Sign Test or Wr for WRS Test) 2 the cfitical value? X Comments:
