热释光材料对热中子响应的灵敏度取决于材料中所含元素的热中子截面和活化核素的特性。~6LiF 常用于测量热中子,利用的是~6LiF(n,α)~3H 反应。热中子辐射场常伴有γ辐射,~7LiF 可测γ辐射,而对热中子的响应可以忽略。~6LiF 与~7LiF 对γ辐射具有相同的能量响应和灵敏度,采用一对(~8LiF 和~7LiF)TLD,就可以测量热中子注量。这种方法的灵敏度虽较高,但其误差较大,在伴随强γ辐射场中难以使用 The sensitivity of a thermo-luminescent material to thermal neutrons depends on the thermal neutron cross-section of the elements contained in the material and the nature of the activated species. ~ 6LiF is commonly used to measure thermal neutrons, utilizing ~ 6LiF (n, α) ~ 3H reactions. Thermal neutron radiation field is often accompanied by gamma radiation, γ radiation can be measured ~ 7LiF, while the response to thermal neutrons can be ignored. ~ 6LiF and ~ 7LiF have the same energy response and sensitivity to gamma radiation, and thermal neutron fluence can be measured using a pair of (~ 8LiF and ~ 7LiF) TLDs. Although the sensitivity of this method is high, but its error is large, difficult to use with strong gamma radiation field
