1验证仪1.1点剂量仪点剂量仪主要有半导体剂量计、电离室和热释光剂量仪(TLD)等。采用点剂量仪测量剂量时,通常是将点剂量仪置于体表或自然腔内测量点。由于点剂量仪体积小,分析相对较简单,故可广泛使用。点剂量仪测量的准确度一般受环境温度影响较大,同时,也受点剂量仪自身的 1 Verifier 1.1 Dosimeters Point dosimeters are mainly semiconductor dosimeters, ionization chambers and thermoluminescence dosimeter (TLD) and so on. When using a Dosimeter to measure the dose, it is common to place the Dosimeter on a body surface or within a natural luminal measurement point. Due to the small spot dosimeter, the analysis is relatively simple, it can be widely used. The accuracy of the point dosimeter measurement generally affected by the ambient temperature greater, at the same time, also by the point dose meter itself
