More Information
Summary:Provided is a radiation monitor, including: a radiation detection unit which includes a radiation detection element, the radiation detection element emitting light of a predetermined light emission wavelength; a light emission unit which emits light of a wavelength different from the light emission wavelength; a wavelength selection unit which passes the light of the light emission wavelength, and is set to a first mode to block the light from the light emission unit; an optical transmission line which transmits the light; a light detection unit which converts the light passing through the wavelength selection unit into an electric pulse; and a control unit which measures a count rate of the electric pulse, and determines whether at least the light emission unit is degraded on the basis of the count rate and a light intensity of the light emission unit.
