| Abstract: | We present the results of an experimental work aimed at improving the performances of the CR-39® (Registered Trademark of PPG Industries Inc.) nuclear track detector for neutron dosimetry applications. The work was done in collaboration with the Intercast Europe S.p.A., producer of CR-39 for commercial and scientific applications. We compare the CR-39 made with different additives concentrations and different polymerization processes. We evaluate the response of the CR-39 to fast neutrons from three sources: 241Am---Be, 252Cf and 238Pu---Li. Particular attention was paid to background fluctuations that limit the lower detectable dose. |
