Abstract

This article reports the thermoluminescence characteristics such as linearity of response, sensitivity, and dose response of thulium-holmium doped silica optical fibers subjected to 60Co gamma radiation source. Thulium-holmium doped optical fibers manufactured by CorActive with core diameter 11.5 ± 1.0 μm were used as the basic material for the research. Samples were irradiated with gamma radiation at doses range from 10 Gy to 100 Gy. Gamma beams were provided by Gammacell 220 Excel available at Applied Physics Study Center, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, Bangi, Selangor. It is found that the commercially available thulium-holmium doped optical fibers have linear dose-TL signal dependence. The average sensitivity of thulium-holmium fibers is 0.094 nC mg-1 Gy-1 and TL yield of absorbed dose is 2.55 nC Gy-1..
