Abstract
The present invention is one that removes noise of a voltage signal to be inputted to a pulse processor, as well as improves radiation energy resolution, and includes: a radiation detectorthat outputs charge generated by incidence of radiation; a preamplifierthat converts the generated charge into an analog signal; an A/D conversion partthat converts the analog signal from the preamplifierinto a digital signal; a denoising filterthat removes the noise from the digital signal from the A/D conversion part; a waveform shaping partthat generates a pulse signal from a digital signal having passed through the denoising filter; a pulse height detection partthat detects peak values of the pulse signal from the waveform shaping part; and a count partthat, on a pulse height basis, counts the peak values obtained by the pulse height detection part, in which the denoising filteris one that removes the noise by taking the weighted moving average of values of the digital signal with use of a weighting factor depending on the difference from a predetermined reference value.
