Abstract
A non-destructive inspection system includes: a neutron emission unit 12 capable of emitting neutrons pulsed; a neutron detector capable of detecting the neutrons emitted from the neutron emission unit and penetrating through an inspection object; a storage unit storing attenuation information indicating a relationship between a material of the inspection object and attenuation of the neutrons; and a calculation unit capable of calculating distance information indicating a position of a specific portion in the inspection object in accordance with time change information which is information on a change over time in an amount of the neutrons detected by the neutron detector. The calculation unit is capable of generating information related to an amount of the specific portion from information based on the amount of the neutrons according to the time change information, using the distance information and the attenuation information.
