LSA 3000液闪谱仪测量低水平氚水活度的参数优化
|
摘要
本工作优化了超低本底液闪谱仪LSA 3000测量水中氚含量的最佳实验条件和测量方法,归纳总结出该谱仪测定低水平氚水活度的最佳测量模式、测量道值、静置时间等参数。并利用所得结论对青岛地区的环境水样进行了测量。
Using an ultra-low background liquid scintillation spectrometer LSA 3000,we optimized the best experimental conditions and measuring methods for measuring the tritium content in water. The optimal measurement pattern,channel and static placing time of the instrument have been carried out by testing low-level tritium water.On the basis of selected parameters,low-level tritium in environmental water samples of Qingdao are measured.
