Optimization of dopants in CR-39

Abstract

CR-39 plastic nuclear track detectors have been cast with noadditive and with Methyl methacrylate, Diallyl phthalate, Dibulyl phthalate and Di-(2-ethylhexyl) phthalate. After irradiated with 5.15 MeV alpha particles, the responses of the detectors were found to be significantly different for each kind of additive. The performance was reported of a new CR-39 (DAP) solid state nuclear track detector, the CSR. The sheets with 1 % addition of Diallyl phthalate of CR-39 monomer were more sensitive than those of pure CR-39.
