PURPOSE:To improve the accuracy of measurement data and to prevent the measurement data from having an omission by providing a correcting means which removes a crosstalk quantity between detectors from the measured values of the detectors. CONSTITUTION:A unit-channel radiation detector consists of a scindillator 1, a light shield material 2, a collimator 3, a photoelectric converting element 4, and an amplifier 5 and many radiation detectors are arrayed to constitute the detection part of the multichannel radiation detecting device. Then the outputs of amplifiers 5 of respective channels are inputted to a crosstalk correcting computing element 6. The output of the computing element 6 is inputted to a calculator memory 7 and a measurement data display device 8. The computing element 6 is stored with correction data regarding the crosstalk quantity between detectors which is measured previously and the outputs of the amplifiers 5 are corrected according to the correction data to find the real quantity of incident radiation. |
