ABSTRACT:
An autoradiography cassette maintains a sample in close contact with a film and prevents extraneous light from exposing the film. The cassette includes a substantially flat base plate and two flexible magnetic sheets. A first flexible magnetic sheet is attached to the base plate by rivets. The rivets allow the first magnetic sheet to move relative to the base plate in a plane defined by the base plate. A second flexible magnetic sheet is positioned above the first magnetic sheet to magnetically couple with the first magnetic sheet. The rivets allow relative lateral movement between the base plate and the magnetic sheets to account for differences in the coefficients of thermal expansion for the base plate and the magnetically coupled flexible magnetic sheets.
