Measurements of high fluences of neutrons and 10B (n,α)‎ 7li reaction products that registered on CR-39 plastic detector using optical density technique

الملخص EN

Optical densities have been measured for two groups of CR-39 nuclear track etch detector samples.

The first group was irradiated with fast neutrons and the other one with a mixed radiation of fast neutrons and 10B (nth,a) 7Li reaction products.

A clear difference was observed in the behaviour of optical density versus etching time between the first and the second group samples.

The optical density was observed to be increased as the incident neutron fluence dose increases.
