NEUTRON FLUENCE AND DOSE MEASUREMENTS WITH FISSION FOIL-LEXAN DETECTORS,

Abstract

A fission foil-Lexan detector system has been developed to monitor reactor neutrons. It is similar to the system based on counting fission gamma rays but has some advantages; i.e., permanently recorded tracks that can be read any time after exposure; integrated recording; microgram amounts of fissionable material needed; independence of fission product distribution; and the elimination of specialized gamma-ray counting equipment. Fission product damage tracks in the Lexan (or mica) are counted under an optical microscope. Fluence is determined from the sensitivity factor of 0.0000116 tracks/neutron-barn. Experimental results are given. (Author)
