Process for nondestructively testing with a desensitized silver halide radiographic layer. [using absorbed radioactive gases]
Patent
·
OSTI ID:7351050
A method is disclosed of nondestructively testing an article for substantially invisible voids adjacent its surface. A radioactive gas is brought into contact with the surface of the article to be tested. It is retained by adsorption on those surfaces presented by the substantially invisible voids and at other surface locations. A silver halide radiographic layer is juxtaposed adjacent the surface being tested, and the location of the radioactive gas adsorbed within the substantially invisible voids is preferentially recorded within the silver halide radiographic layer.
