Advantages and Possibilities of Cellulose Nitrate Detectors in Corpuscular Imagery

Abstract

The relatively low, but adjustable contrast given by cellulose nitrate films permits, in neutron radiography to record very fine details in images contrary to the high contrasted silver halide images. The resolution is excellent. The simplicity of use is remarkable: all operations are made in full light, the insensivity to gamma rays permits use in direct, non filtered neutron beams and the radiography of gamma active objects. The converter screens used with cellulose nitrate are non-activable. This is not the case for converters used with X rays films. Cellulose nitrate films are excellent for alpha or proton autoradiographs, visualising Boron, Lithium, Nitrogen, etc. extremely interesting for Medicine, Biology, Industry, etc.
