Abstract
A scintillation light detecting device distinguishes between signals from scintillator elements. The device includes a scintillator array. In the scintillator array, the scintillator elements have mutually different decay time constants for emitted light generated as a result of an incident radiation event. A photomultiplier tube that receives light output from the scintillator elements and converts the light into an electrical signal. In relation to the event, an arithmetic processing device detects a peak value and an integrated charge quantity in a voltage waveform of the electrical signal from the photomultiplier tube, and identifies the scintillator element in the scintillator array to which the electrical signal, resulting from the incidence of radiation onto the scintillator element, is attributable, in accordance with a ratio between the detected peak value and integrated electric charge quantity.
