Abstract: A method of and apparatus for measuring radioactivity, which determines energy spectra of radiation rays which are detected by a radiation sensor through a collimator arranged in front of a radiation detector, calculates a spectrum index on the basis of an intensity of scattered rays and an intensity of unscattered rays among the radiation rays determined by distribution of the energy spectra, calculates a density of the object to be measured or a value relating to the density of the density of the object to be measured on the basis of the spectrum index, and meters the radioactivity of the object to be measured on the basis of the value relating to the density and the intensity of the unscattered rays by one measuring step for every cross-section of the object to be measured.

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.
