    摘要： A non-destructive inspection system 1 includes a neutron detecting unit 4 and an arithmetic unit 60. The neutron detecting unit 4 includes a collimator 30 and a neutron detector 20 integrated together. The collimator 30 has a wall defining a through passage P. The wall is made from a material that absorbs neutrons produced via an inspection object. The neutron detector 20 is capable of detecting neutrons that have passed through the collimator 30. The arithmetic unit 60 generates information on a position and composition of the inspection object, based on information on the neutrons detected by the neutron detector 20, positional information indicating the position of the neutron detecting unit 4, and posture information indicating the posture of the neutron detecting unit 4. The positional information and the posture information are detected by a position and posture detecting unit 5.

    摘要： A nondestructive inspecting device 1 is provided with: a neutron beam emitting unit 10 capable of emitting a neutron beam in a prescribed emission direction D1; a gamma ray detecting unit 20 capable of detecting a gamma ray incident from a prescribed detection direction D2 intersecting the emission direction D1; a device housing 30 which covers the neutron beam emitting unit 10 and the gamma ray detecting unit 20, and in which an opening portion 30a is formed in the emission direction D1 and the detection direction D2; an outer shutter 31 for opening and closing the opening portion 30a of the device housing 30; an external dose monitor 41 for detecting a radiation dose inside the device housing 30; an internal dose monitor 42 for detecting a radiation dose outside the device housing 30; and a control unit 40 for prohibiting opening of the outer shutter 31 if the radiation dose detected by at least either of the dose monitors 41, 42 exceeds a predetermined threshold.
