摘　　要：氟化锂 (LiF)热释光探测器对带电粒子的响应主要依赖于粒子的传能线密度 (LET)。高LET能引起探测器响应降低 ,从而造成低估辐射剂量。本文综述了国内外LiF探测器对带电粒子LET的响应 ,提出了解决高LET带电粒子剂量贡献的新思路。Response of LiF thermoluminescence (TL) detector to charged particle is dependent on particles’ LET. High LET can cause reduction of detector response and underestimation of radiation dose. This paper summarized the response of LiF detector to charged particles’ LET, and suggested a new approach to solve the dose contribution of high LET charged particles.
