Abstract
The observed response of CR-39 based personnel neutron dosimeters may be influenced significantly by the environment in which the dosimeters are exposed. One of the factors which may effect the performance of t he dosimeters is the presence of gamma rays with neutron fields. To qu antify this, samples of CR-39 are exposed to neutrons, gamma rays, alp ha particles and fission fragments under various conditions. The effec t of presence of gamma rays with neutrons on the response of CR-39-bas ed neutron dosimeter is investigated. The influence of gamma rays on e tching characteristics of CR-39 is also studied. Our results indicate that high gamma radiation doses significantly influence the response a nd etching characteristics of the dosimeter.
