PROBLEM TO BE SOLVED: To provide a radioactivity inspection apparatus capable of discriminating a concentration difference of radioactivity within an inspection object, in an inspection to an inspection object including a plurality of individual pieces.SOLUTION: In a radioactivity inspection apparatus, detectors 7a-7d and detectors 8a-8d are connected to a control part 100. The control part 100 includes an arithmetic unit such as a CPU, and a storage unit such as RAM and ROM, and operates as a control unit for controlling an entire operation of the radioactivity inspection apparatus. The control part 100 includes as a functional configuration: a conveyance control part 101; a counting part 102 individually counting the number of radiation rays detected at each of the detectors 7a-7d and the detectors 8a-8d; a determination part 103; a concentration difference detection part 104; a measurement time extension part 105; a display control part 106; and a storage part 107. The control part 100 is further connected to a display part 9. |
