CABLE INSPECTION DEVICE AND CABLE INSPECTION METHOD
A cable inspection device non-destructively inspects a cable used for supporting a bridge. The cable inspection device includes a neutron source and a neutron detection device. The neutron source emits neutrons to the cable. The neutron detection device includes a detection surface arranged outside the cable, and detects target neutrons and measures the number of the detected target neutrons when neutrons are emitted to the cable. The target neutrons are among the neutrons released from the cable and incident on the detection surface, and each have an energy equal to or lower than a predetermined value that is lower than an energy of a fast neutron.
