液闪谱仪在低水平测氚中测量条件选择

Selection of Experimental Conditons in Measuring Tritium at Low Level by the Liquid Scintillation

在低水平测氚中,分别从闪烁液、计数区间、有机相(闪烁液)与水相(试样)的体积比和计数时间的影响因素考虑,对测量条件做出选择,从而达到降低液闪谱仪的探测下限和提高仪器的使用效率的目的。

In selection of conditions for measurement of tritium at a low level, factors that influence the liquid scintillator, counting interval, volume ratio of organic phase （liquid scintillator） and water phase （samples） , counting time are considered, thus to lower the detectable limit and improve efficiency of the instrument .
