PURPOSE: A film cassette for a radioactive ray transmission test is provided to get better geometrical sharpness by making a film adhere to a lead foil intensifying screen and to easily attach and detach a test piece and a film cassette by forming a film cassette body of a magnetic material. CONSTITUTION: A film cassette is made of a magnetic material, thus, a film in the film cassette and a lead foil intensifying screen closely adhere with the film cassette. A test piece and the film cassette are attached and detached easily. The film cassette comprises a body(15) having an opening(23), a bended portion(22) formed in one portion of the opening of the body, and velcro(20,21) opening and closing the opened portion. |
