<p>A radiation measuring device includes: a detector that detects radiation; a preamplifier that amplifies a signal outputted from the detector; a shaping amplifier that shapes the waveform of the signal outputted from the preamplifier; an A/D converter that converts the analog signal output from the shaping amplifier to a digital signal; and a digital data processing unit that calculates digital signal output from the A/D converter, wherein 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 the pulse height information of the current pulse digitalized by the A/D converter, the generation time information of the preceding pulse, and the pulse height information of the preceding pulse.</p> |
