The objective of the present invention is to provide a signal processing device capable of calculating the detection time at which a radiation detection device detects radiation by taking into account the characteristics of the radiation detection device. This signal processing device (3) for processing an output signal from a radiation detection device (2) including a plurality of scintillators, which emit fluorescence according to incident radiation, and a plurality of light-receiving elements, which detect fluorescence, comprises a processor that executes: an identification process for identifying, from the output signal, the detection time at which the light-receiving elements detected the fluorescence emitted by the scintillators and the imparted energy imparted to the light-receiving elements; and a calculation process for calculating, as the detection time at which the radiation detection device detected the fluorescence, a weighted average of the detection times detected by the light-receiving elements, wherein the weights are the n-th power (n is a real number greater than 1) of the energy corresponding to each of the light-receiving elements.
