Abstract

PURPOSE:To offer a radiant ray inspection mask which can be installed easily and can be manufactured easily, by using metallic powder or metallic oxide powder of a permanent magnet material, for a part of a radiant ray absorbent, and performing its magnetization working. CONSTITUTION:As for rubber or soft synthetic resin being a bonding material, rubber such as natural rubber, isoprene rubber, etc., and polyvinyl chloride, etc. are used, as for a radiant ray absorbent of a permanent magnet material, powder such as barium ferrite, ferrite, etc. is used, and as for the third component for making up for absorbing power against a radiant ray, a lead compound, etc. are used. As for a mask 5, said materials and a mixture to which chemicals for rubber have been added in accordance with a regular method are vulcanized and molded, and after molding, magnetization working is performed to a press- contact surface 5a contacting with an object to be inspected, by a capacitor type magnetizer. The press-contact surface 5a of the mask 5 is formed so as to go along the surface shape of the object to be inspected 1, and when the object to be inspected 1 is covered with this mask, the whole radiation transmission quantity factor is almost equalized, therefore, thickness of each part of the mask 5 is varied in advance.
