<p>PURPOSE:To enable a personal exposure dose to be properly managed by enabling a plurality of types of dosage equivalent weights to be directly measured and the dosage equivalent weights at a low-energy radiation region to be also directly measured. CONSTITUTION:A title item consist of filter groups 21a-21d which are constituted by a combination of at least two types of metal filters, a plastic filter, etc., and one or a plurality of fluorescent glass elements which are placed at a position opposing these filters and then light is excited for the fluorescent glass element which is exposed to radiation through these filters. At this time, a plurality of types of dosage equivalent weights are obtained by using a fluorescent detection amount and a dosage equivalent weight conversion coefficient which are obtained from both portions of a side opposing a filter of the fluorescent glass element at this time and by using a specified calculation expression.</p> |
