Answers to the foilowing questions should be fully documented in the Survey Unit Release Record
- 1.
Have surveys h e n performed in accordance with survey inshctions In the Survey Design?
- 2.
Is the instrumentation MDC for structure static measurements below the DCGLW for Class I and 2 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 DCGLW 7
- 4. Was the instrumentation MM: for structure scan measurements, sol scan measurements, and ernbeddedlburied piping scan measurements bdow the DCGLh: or, if not was the need for additional 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
- 6. Were the MDCs and assumptions used to develop them appropriate for the instruments and techniques used to perform the survey?
- 7.
Were the survey methods used to collect data proper for the types of radiation involved and fw the media being surveyed?
- 8. WereUSpecial Methods' for data collection properly applied for the survey unit under r w l M Q. Is the data set comprised of qualified measurement results collected in accordance with the suwey design, which accurately refteds the radiologicaf status of the facil'rty?
