PURPOSE:To satisfactorily execute multinuclide separation measurement by providing a multichannel waveheight analyzing circuit and a recording part to store multinuclide energy spectrum data. CONSTITUTION:A multinuclide separation type radiation measuring device is composed of a detector 10 to detect radiation, multichannel waveheight analyzing circuit 18, counting circuit 20, storing part 22 and control part 24. Radiation measurement is executed in the circuit 18 by using an (n)-types of nuclide standard sample, for which the possibility of separation measurement is left, and the energy spectrum data is recorded. Next, when the plural nuclides to be separately measured is designated, the control part 24 reads the energy spectrum data from the storing part 22 and the coefficient value of another nuclide mixture rate, which is a correcting value, is calculated. When the radiation quantity of a certain nuclide is separately measured, the channel is selected by the circuit 18, however, the correcting value is simultaneously calculated and outputted as well. Thus, this arithmetic of the correcting value is automatically executed by selecting and designating the plural nuclide to be separately measured.
