Abstract
A radiation detector is offered which can suppress generation of sum peaks. The radiation detector () has a radiation detection portion (), a first differential filter portion () for converting the output signal Sfrom the detection portion into a first pulsed signal Sa second differential filter portion () for converting the output signal Sinto a second pulsed signal Sa third differential filter portion () having a time constant longer than that of the second differential filter portion () and operative to convert the output signal Sinto a third pulsed signal San event detection portion () for outputting an event signal Sa pileup detection portion () for outputting a pileup signal Sin response to the ratio between the pulse height of the second pulsed signal Sand the pulse height of the third pulsed signal Sand a pulse height detection portion () starting to detect the pulse height of the first pulsed signal Sin response to the event signal Sand outputting a detection signal SThe pulse height detection portion () stops from outputting the detection signal Sin response to the pileup signal S
