近年来,因LiF(Mg,Cu,P)TLD具有CaSO_4(Dy)的高灵敏度和LiF(Mg,Ti)的能响好的双重优点,引起国内外越来越大的关注和兴趣,应用范围日益扩大。在环境和个人剂量测量时,人们总是希望既保证有足够小的重复使用误差,又能简化重复使用程序。 LiF(Mg,Ti)在重复使用中如不经400℃一小时的高温退火和80℃,24h(或100℃,2h)的低温退火,其灵敏度和发光曲线将会发生显著的变化。LiF(Mg,Cu,P)即使在较大剂量下重复使用,也只需240℃,10min的常规退火,其主要作用是消除前次测量的残余剂量读数。由于这种探测器的测量读出温度和常规退火温度恰好相等,并具有与LiF(Mg,Ti)
In recent years, LiF (Mg, Cu, P) TLD has the double advantages of high sensitivity of CaSO 4 (Dy) and good reactivity of LiF (Mg, Ti), attracting more and more attention and interest at home and abroad. Growing. In the environment and personal dose measurement, people always hope that both to ensure that there is a small enough re-use error, but also to simplify the re-use of the program. LiF (Mg, Ti) will undergo significant changes in its sensitivity and luminescence curve if it is not annealed at 400 ℃ for one hour and annealed at 80 ℃ for 24h (or 100 ℃ for 2h). LiF (Mg, Cu, P) only requires conventional annealing at 240 ° C for 10 min even with repeated use at higher doses, with the main effect of eliminating residual dose readings from the previous measurements. Due to the fact that the measurement readout temperature of this detector is exactly equal to the normal annealing temperature and has the same composition as LiF (Mg, Ti)
