摘要：

CR-39 detectors have been irradiated with both Am-241 alpha particles and protons in the energy range of 1.0-5.5 MeV and 0.8-2.8 MeV, respectively. The proton irradiation has been achieved through two different techniques: Rutherford Backscattering (RB) and Nuclear Reaction (NR). The detectors were chemically etched in a hot KOH solution for periods ranging from 0.5 h to 3 h for alpha particles and 2.5 to 5.5 h for protons. The track diameter variation as a function of particles energies and etching time has been studied. A new predictive model based on experimental track parameters has been developed for the studied particles and for variable bulk track etching velocities. This predictive model is based on a single parameter beta determined by fitting our experimental data.
