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.

Nondestructive identification method and nondestructive identification device

An insulating shield plate (1) divides a room of an electrolysis bath (2) into an anode chamber (13) and a cathode chamber (14). An anode (5) is disposed in the anode chamber (13), and a cathode (6), metallic waste (7) and heater (4) are disposed in the cathode chamber (14). An electrolyte (3) stored in the electrolysis bath (2) flows in a circulation path from a circulating pump (10) through a circulating line (12) and filter (11) to return the electrolysis bath (2). An exhaust gas processing device 9 is connected to the electrolysis bath (2). When a voltage is supplied to the anode (5) and cathode (6), a surface of the metallic waste (7) is charged in a positive polar to dissolve a base metal of the metallic waste (7). Further, a cylindrical anode (33) is arranged in an electrolyte (32) in an electrolysis bath (31), and a cylindrical metal (34) as a metallic waste is arranged in the cylindrical anode (33). After a bar-shape cathode (35) is arranged in the cylindrical metal (34), a DC voltage is supplied to the cylindrical anode (33) and the bar-shape cathode (35). At this time, the system may be constructed in that oxygen occurs by charging in a positive polarity an inner surface of the cylindrical metal (34) and the base metal of the cylindrical shape is dissolved.
