Abstract

A uniform source of nuclear radiation is produced by converting a convertible surface portion of a body. The conversion can be by chemical combination or reaction, neutron bombardment, ion exchange of an element present in the convertible material with a solution of radio-active ions of the element or by permitting the radio active particles to be embodied into the surface portion. A preferred embodiment utilises conventional photographic film in which the silver halide grains are treated chemically with a radio-active material.
