Abstract:ISO standard 4037 specifies limits for scattered radiation for "gamma reference radiation" for the calibration of "protection-level dosemeters and rate dosemeters." More specifically, it specifies that scattered radiation should contribute less than 5% to the total exposure rate for source-center-to-dosimeter-center distances (henceforth called downrange distances) over which dosimeters are calibrated. In a previous paper by the authors, the results of an MCNP analysis of a calibration range with a Cs irradiat… 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.
