In this paper, the energy response of the solid state nuclear track detector PM-355 for α-particles within the energy range of ≤ 5.5MeV have been studied using an 241 Am(1µci) source in irradiating the detectors pieces. It has been found that the threshold energy, which defined as the minimum energy that could be detected, is about 0.3 MeV for PM-355. While the track detector CR-39 responses to the α-energy approximately up to 0.2 MeV, when a conventional chemical etching is used. The results also indicates that the etching efficiency and sensitivity of the CR-39 is better than that of PM-355. They
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
