Abstract
A .gamma. ray emitted from a reference radioactive ray source is radiated from outside to a solid radioactive waste. The radioactive intensity of the .gamma. ray emitted from the solid radioactive waste is measured during the radiation of the .gamma. ray. The radioactive intensity to be measured is discriminated into the first radiation intensity based on the reference radioactive ray source and the second radiation intensity based on the radioactive nuclide of the solid radioactive waste. A radiation absorption coefficient of the solid radioactive waste is determined based on the first radiation intensity. The distribution of radioactivity of the solid radioactive waste is determined based on the radiation absorption coefficient and the second radiation intensity.
