PURPOSE:To provide a radiation measuring equipment in which the incident radiation dose can be measured accurately by suppressing the count miss caused by piling up of output pulse signal from a detector when radiation from an accelerator facility, where the radiation from an object 15 known, is monitored, for example. CONSTITUTION:An output pulse signal from a detector 10 is amplified through a preamplifier 11 and a main amplifier 12 and a pulse, having a peak value higher than a predetermined value, is discriminated through a peak discriminator 13 before being counted by means of a counter 14. An A/D converter 15 converts an output pulse signal from the preamplifier 11 into a digital value representative of the number of radiation particles corresponding to the peak value of the pulse signal. A correction operating unit 16 corrects the count of the counter 14 based on the digital value obtained from the A/D converter 15.
