GLASS DOSIMETER AND ITS CALIBRATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a measuring apparatus measuring an individual's exposure dose and its calibrating method in an accelerator or the like irradiating energy higher than energy radiated from a nuclide used in calibration of a common radiation measuring apparatus. SOLUTION: Exposure dose of people performing maintenance by stopping the accelerator or the like are measured more accurately to determine an exposure dose more accurately when an accident or the like occurs and reflect it on medical treatment or the like. This glass dosimeter has a plurality of shields 31A laminated on a glass dosimetric element 31. Calibration is performed by using a corpuscular ray treating device which is to be actually used.
