Abstract
A nondestructive identification device includes: a radiation sourceirradiating an x-rayto a standard samplemade of a known material and a sample; a sensordetecting a radiation ray having transmitted the standard sampleand the sample; a signal processing deviceconverting a signal of the sensorinto an image; an image processing devicewhich performs adjustment on an entire second image to make a luminance value of a part of the standard samplein the obtained image or a relation between the luminance value and a thickness of the standard samplein a first image where the energy of the radiation sourceis first energy be the same as that in the second image where the energy of the radiation sourceis second energy, and which performs a computation processing to take a difference or a ratio between the adjusted second image and the first image; and a display devicedisplaying an image.
