Pulsed photoluminescence measurements using salt as a radiation accident dose detector material

Abstract

To realize the retrospective measurement of public dose levels after a nuclear emergency, the optically stimulated luminescence radiation dose-response characteristics of salt were studied, and the relationship between the salt optically stimulated luminescence signal and ionizing radiation dose was determined. The effects of natural light, storage time, and preheating temperature on the salt optically stimulated luminescence signal were examined. The results show that salt as a photoluminescence dose measurement material has the advantages of convenient sampling, high throughput, short detection time, wide dose range, and low detection limit. The study lays the technical foundation for achieving the public dose assessment of salt pulse photoluminescence.
