Radiation monitor and method of monitoring radiation

Abstract

A radiation monitor 1 includes a light-emitting unit 10 which generates light having an intensity depending on an amount of an incident radiation, an optical fiber 20 which sends a photon generated by the light-emitting unit 10, a photoelectric converter 30 which transmits one electric pulse to one sent photon, a dose calculation device 40 which counts the electric pulse amplified by the photoelectric converter 30 and converts the counted value of the measured electric pulses into a dose of the radiation, and a display device 50. The dose calculation device 40 counts the electric signals converted from the photon by the photoelectric converter 30 to calculate a counting rate, and stops the counting when the counting rate exceeds a predetermined threshold, and performs counting when the counting rate is less than the threshold.
