A new dosimeter for measuring hot particle dose rates

This paper reports that conventional methods used to estimate the dose delivered to the skin of a worker by a hot particle rely on the use of relatively inaccurate measurement techniques or the application of computer models requiring significant particle analyses. In contrast, exoelectron dosimeters have been demonstrated to provide accurate, direct measurements of hot particle dose rates. The sensitive layer of exoelectron dosimeters is extremely thin (100-nm). This physical property allows an accurate skin dose estimate to be reenacted with a captured hot particle.
