Abstract:
1. A radiation measuring device comprising: a detector that detects radiation; a preamplifier that amplifies a signal outputted from the detector; a shaping amplifier that shapes a waveform of the signal outputted from the preamplifier; an A/D converter that converts an analog signal output from the shaping amplifier to a digital signal; and a digital data processing unit that calculates digital signal from the A/D converter, wherein the energy information of the radiation inputted to the detector is obtained from a pulse height of the pulse signal processed by the preamplifier and the shaping amplifier, and the pulse height of the current pulse is corrected in the digital data processing unit by performing an arithmetic operation using pulse height information of the current pulse digitalized by the A/D converter, generation time information of the preceding pulse, and pulse height information of the preceding pulse.
