Paper Abstract

In an explosive experiment, the effects of extra covers of thin plane plate, hollow wedge or cone placed in the front of the cassette protector assembly which consisted of three layers of interspaced aluminum plates were analyzed by comparing the optical densities of the x-ray films inserted between the layers. With the plate cover, all the plates of the protector assembly were severely deformed. And all the films were severely darkened owing to the impacts of deformed plates as well as the transmitted shock waves. With wedge or cone cover, no apparent deformation of the assembly plates was observed, and only the first film showed slight darkening owing to the shock waves. When a large amount of explosive has to be used or the film plane has to be placed very close to an explosion source, the cone type of extra cover can protect the film cassette from the explosive blast without degrading the radiographic image quality.
