摘要: Key characteristics of a newly prepared tissue-equivalent, highly sensitive thermoluminescence dosimeter, Li2B4O7:Cu,Ag,P, are presented. The material was developed at the Institute Nuclear Sciences, Belgrade, in form sintered pellets. A new preparation procedure has greatly increased sensitivity basic copper activated lithium borate and glow curve Li2B4O7 : Cu,Ag,P consists well-defined main dosimetric peak situated about 460–465 K with which is four to five times higher than that LiF Mg,Ti (TLD-100). exceptionally good response features attributed incorporation Cu as dopant. Both low high temperature emission spectra presented origins various bands considered. Additional data provided from electron paramagnetic resonance measurements.
