Abstract:We examined the suitability of taking smear tests (DIN ISO 7503.1) to evaluate surface activity. Special respect was given to mixtures of nuclides typical for the nuclear industry. We analysed the nuclides of samples of different fuel pools to evaluate the smear test measurement technique. Special calculations were carried out to examine the amount of nuclides that are difficult to measure due to their low maximum decay energy of less then 0.15 MeV (e. g. 55Fe, 63Ni). The response characteristic, detection sen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
