PROBLEM TO BE SOLVED: To solve a problem that it is difficult to determine that a γ-ray is emitted from which of nuclides, from a measuring result.;SOLUTION: A radioactivity measuring apparatus comprises: a container storing a measurement target; a first detection unit emitting fluorescent light in response to a radiation released from the measurement target stored in the container; a second detection unit emitting fluorescent light in response to the radiation released from the measurement target stored in the container, and higher in an energy resolution and larger in an area for receiving the radiation from the measurement target than the first detection unit; and a calculation unit calculating radioactivity of a radioactive substance of at least one nuclide among radioactive substances of a plurality of nuclides released from the measurement target on the basis of a detection amount of the fluorescent light detected by the first detection unit and a detection amount of the fluorescent light per energy band detected by the second detection unit.;COPYRIGHT: (C)2015,JPO&INPIT
