The Radiological Impact From Radioactive Contamination That Is Not Readily Detectable Using Beta-Sensitive Survey Devices


R. M. Nicoll


Over 60% of the dry active waste (DAW) generated in a typical commercial reactor can consist of nuclides that are not readily detected using conventional beta-sensitive detectors. This has generic implications for the commercial power industry since the accepted industry practice for releasing radmaterial and personnel is based on beta-sensitive detection. It has been the industry assumption, that as long as a significant quantity of beta-emitting isotopes is present in plant waste streams, the unauthorized release of non beta-emitting contamination is unlikely. A technical basis is presented that can be used to test the validity of this assumption. This article presents a revision and enhancement of methodology previously published by the author.
