X-RAY INTENSITY ADJUSTING BODY, X-RAY FOREIGN MATTER INSPECTION METHOD USING IT, AND X-RAY FOREIGN MATTER INSPECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To easily use an X-ray intensity adjusting body at the time of nondestructive inspection.;SOLUTION: The X-ray intensity adjusting body 1 is provided with a circular opening part 1a on the upper surface and a circular hole part 1b on the bottom face. In the internals of the X-ray intensity adjusting body 1, a tapered part 1c forming a conical surface is formed connecting from the opening part 1a to the hole part 1b. By using the X-ray intensity adjusting body 1 at the time of taking X-ray image of an inspection object 11 of spherical shape together with the X-ray intensity adjusting body 1, the intensity of the X-ray image transmitted through the inspection object 11 and the X-ray intensity adjusting body 1 is made approximately uniform over the whole of the inspection object 11, and a precise nondestructive inspection is thereby performed. If the inspection object 11 is mounted in the tapered part 1c through the opening part 1a with the X-ray intensity adjusting body 1 arranged between an X-ray area camera 3 and an X-ray source 2, the inspection object 11 is easily inspected.;COPYRIGHT: (C)2010,JPO&INPIT
