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 tracksneutron-barn. Experimental results are given. Author
