PORTABLE RADIATION DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a portable radiation detector for achieving temperature compensation means by a relative simple constitution.

SOLUTION: A portable radiation detector 1 includes: a scintillator 11 for emitting light when radiation is applied; a photodetector 12 for converting light emitted from the scintillator 11 into an electric signal; and a power supply part 20 including a battery 21 for supplying bias voltage to the photodetector 12 and connecting a temperature sensor 25 for changing a current value in accordance with a temperature change between the battery 21 and the photodetector 12.
