DOSE RATE MEASUREMENT DEVICE

摘要

Three semiconductor detectors (22) are disposed at equal intervals from the central axis of a scintillation detector (21) and at equal angles from a plane intersecting the central axis at a right angle in positions that do not obstruct the incidence of radiation on the scintillation detector (21). An energy correction coefficient is determined on the basis of an average pulse-height value determined from a second pulse-height spectrum obtained from analog voltage pulses output from the semiconductor detectors (22), and a high-range-dose-rate energy characteristic determined from the DC voltage output from the scintillation detector (21) is corrected.
