Abstract
The energy calibration method detects irradiation of radiation with predetermined energy from a calibration radiation source using a plurality of radiation detectors having a peak value distribution whose mode and mean value are different and performs calibration so that mean values become identical within the peak value distributions of the respective radiation detectors obtained through irradiation of radiation with predetermined energy from the calibration radiation source.
