1. A non-destructive inspection apparatus that irradiates an inspection object with a neutron beam to analyze an internal structure of the inspection object based on a radioactive ray generated in reaction with the neutron beam, the non-destructive inspection apparatus comprising:
a neutron emission unit capable of emitting the neutron beam along a predetermined emission line;
a radioactive-ray detector capable of detecting the radioactive ray incident in a predetermined detection line intersecting the emission line;
an apparatus case covering the neutron emission unit and the radioactive-ray detector, the apparatus case including an opening on paths of the emission line and the detection line;
a shutter configured to open and close the opening of the apparatus case;
a dose detector provided on the apparatus case and configured to detect a radioactive dose;
an apparatus communication unit capable of transmitting apparatus information including the radioactive dose detected by the dose detector to an outside and capable of receiving inspection permission information from the outside; and
an apparatus control unit configured to open the shutter to allow emission of the neutron beam from the neutron emission unit upon acquisition of the inspection permission information from the outside via the apparatus communication unit.
