摘要

PROBLEM TO BE SOLVED: To provide a radiation signal processor achieving radiation irradiation stop control with high accuracy in a system performing radiation irradiation stop control by radio.SOLUTION: The radiation signal processor includes: an AEC signal reception part for receiving a digital irradiation stop advance notice signal transmitted by radio from an electronic cassette 20 and outputting the received digital irradiation stop advance notice signal to an AEC signal conversion part; the AEC signal conversion part which acquires an analog signal (voltage signal) of voltage corresponding to the irradiation amount of radiation by converting the digital irradiation stop advance notice signal into an analog unit voltage increase signal and which performs time integration and outputs the analog signal; and an AEC signal transmission part for outputting the voltage signal acquired by the conversion of the AEC signal conversion part to a radiation irradiation control part 23 of a radiation generation device 12 connected through a wire-line.
