An X-ray detection signal processing device (10), or the like, according to the present invention is provided with a comparator (17) for emitting a high signal when the level of a signal from a tail-pulse preamplifier (13) having an RC circuit (13a) does not exceed a prescribed upper limit value and emitting a low signal when the level exceeds the prescribed value and a control unit (18) for outputting, to a clock oscillator (15), the transition of the comparator (17) signal from low to high after a delay of a prescribed time, outputting the low signal to the clock oscillator (15), stopping oscillation, and thereby stopping high-speed A/D conversion by a high-speed A/D converter (14) and maintaining an output value. |
