Abstract
The recently developed method of etching fission fragment tracks in mica appears to be applicable to the measurement of neutron exposures in irradiation tests. The sensitivity of the method depends on the concentration of fissile elements. The naturally occurring uranium which is present in trace quantity can be used to measure thermal neutron exposures of 1016 to 1021 neutrons/cm2. Deposition of fissionable material on the mica would increase the sensitivity to permit measurement of 106 to 1011 neutrons/cm2. Density counts are reproducible to approximately 5% by using simple laboratory techniques.This publication has 3 references indexed in Scilit:
