Radiation Release and Contamination Control Quiz

Study Notes

Items suspected of containing beta emitters, such as components from PWR waste gas or BWR off gas systems, must be surveyed with an instrument capable of detecting beta activity.
In addition to typical release survey requirements, items which could have been contaminated with alpha contamination must be surveyed with an instrument capable of detecting alpha contamination.
Smoke detectors, or other plant equipment containing radioactive sources, cannot be free released without RP Supervision approval.
Alarms on a TEM indicate the presence of radioactive material and proper contamination controls will be implemented by the RP Technician in response to alarms.
Items suspected of containing natural radioactive material, such as welding rods or camera lens, can be released, with RP Supervisor approval, after gamma spectroscopy indicates only natural products are present and any unidentified gamma photo peaks have been resolved.
Items may be considered free released as long as all of the following criteria are met: no detectable fixed activity above background, no detectable loose surface contamination, no detectable/ suspected internal contamination, and no detectable alpha contamination.
For the release of a large volume of equipment, or for the release of very large items, a survey plan should be developed using Attachment 3, Unconditional Release Survey Plan.
Radionuclides should be sampled or monitored prior to entry to establish a baseline for subsequent release from the RCA.
This will be performed at the discretion of Radiation Protection Supervision.
Items which have been proved to contain only naturally occurring isotopes will not require sampling or monitoring.

Description

Test your knowledge of release survey requirements and contamination control in radioactive material handling. This quiz covers topics such as surveying for beta and alpha activity, free release criteria, and sampling for radionuclides.
