Modern Personal Radiation Monitoring Methods in Japan

Abstract

During the 20^th century, film badges have been applied to the most of our personal radiation monitoring in Japan. Now just at a time entering into the 21^st century, solid-state dosemeters are widely being employed in place of film badges. Here I will describe the exposure measurement principles and characteristics of some newly developed solid-state dosemeters as well as those of existing film badges. Details are explained of the Luxel optically stimulation dosimetry badges which Nagase-Landauer are now starting to use for our personal radiation monitoring services. Finally perspective views are presented of this area in Japan.
