Description/Abstract:
It has been customary to use solid films of active material in the parallel plate pulse counting chambers. The material is deposited over a constant area on every film and the film weight is allowed to determine the thickness. Since both alpha and fission particles have extremely short ranges in solid material, some of the particles producted in the film will be absorbed by the film and will never escape to the surface to be counted. We shall derive an expression for the total number of disintegrations in the film as a function of number of particles counted.
