热释光读出系统的本底信号涨落,由以下几个因素决定:(1)光电倍增管的暗电流;(2)来自加热盘和热释光材料表面的热辐射;(3)一切非电离辐射引起的热释光(NRL—TL)即所谓的“假荧光”。对前两个影响因素,可通过挑选性能优良的光电倍
Fluctuation of the background signal of the TL system is determined by the following factors: (1) dark current of the photomultiplier tube; (2) thermal radiation from the heating plate and the surface of the thermoluminescent material; (3) Non-ionizing radiation-induced thermoluminescence (NRL-TL) is the so-called “false fluorescence.” The first two influencing factors can be selected by excellent performance photoelectric times
