ABSTRACT:
An improved photographic process in which the images on exposed plates are intensified by replacing the silver grains in the photographic plate with an element having more favorable nuclear properties than the replaced silver, and forming a secondary image by autoradiography, which in some cases is produced after activation of the plates by exposure to a neutron flux.
