摘要
用^(109)Cd源激发,Si(Li)探测器探测的能量色散X射线荧光法和薄膜技术法对高放废液样品中铀元素进行分析。测量中对Si(Li)探测器进行死时间校正。将原始样品稀释到可测量水平时,用外标法对铀进行分析,其精度好于3%。在样品中重加10μg的铀,回收率是101% 107%。
An energy dispersive X-ray fluorescence spectrometry with ^(109)Cd isotopic exciting source and S (Li) detector are used to analyse uranium in the high-level liquid waste. Film technique is used for preparation of the measured source. For the elimination of effect of radiation on Si (Li) detector, the dead time must be corrected in measurement. After the initial sample is dilluted to measurable range, uranium is analysed by external standard method. The precision of the method is better than 3%. The recovery of U is (101—107)% with 10 μg uranium added to the sample.
