Abstract

An object is to provide a nondestructive inspection device of a low equipment cost, and a crane equipped with the nondestructive inspection device. The nondestructive inspection device is provided for a quay crane, on a transporting route of the container. The nondestructive inspection device irradiates radiation from radiation sources to a container which has entered into an inspection area, and detects radiation that has transmitted through the container using the same detector, and nondestructively inspects the entire inside of the container based on information of intensity of the radiation and information of detection position of the radiation. The nondestructive inspection device is provided with; a modulation device which assigns different modulations to each radiation emitted from each of the radiation sources, and an identification device that distinguishes the modulation assigned to the radiation incident on the detector based on the output of the detector, and identifies which one of the radiation sources this radiation has been emitted from.
