A rotating lead disk with radial collimating slits is placed between the active specimen and the x-ray film. The factor which determines whether the radiograph will be fogged by gamma rays then becomes the activity per unit length of the specimen rather than the total activity. The successful reduction of background fogging by the device is demonstrated. The extension of radiography to the study of very highly active specimens is indicated.
