description PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnosis apparatus for avoiding a worker from being exposed to a radiation, and implementing a maintenance when the maintenance of a detector installed in the nuclear medicine diagnosis apparatus is implemented.SOLUTION: The radiation detector 10 includes a scintillator 11 having a strip shape, and a plurality of photoelectron multipliers 12 two-dimensionally disposed. A planar light guide 30 is installed in the front of the scintillator 11, and formed by juxtaposing a plurality of optical fibers. A light source 20 is installed at one end of the light guide 30. When the radiation detector 10 is inspected, the light source 20 emits a light. The light emitted from the light source 20 enters into the scintillator 11 through the light guide 30. It determines whether there is a failure in the radiation detector 10, based on an output from the radiation detector 10 on the basis of the light from the light source 20.
