Abstract

A method for tritium determination in air precipitation via electrolytic enrichment and liquid scintillation counting (LSC) was developed at the Institute of Nuclear Physics, Polish Academy of Sciences (IFJ PAN). Tritium activity was measured using a Tri-Carb 5110TR counter at the University of Silesia. Calibration was performed with tritiated water (142 Bq/g, June 11, 2019). Additionally, three water samples from Almera 2023 and ICHTJ 2023 were analyzed. The method was validated based on these interlaboratory tests. The detection limit of 1.1 Bq/kg enables precise environmental monitoring. The study presents tritium activity in precipitation collected in February 2023 in Krakow, Poland.

用电解浓缩和液体闪烁计数光谱仪测量波兰克拉科夫沉淀中的氚

波兰科学院核物理研究所（IFJ PAN）开发了一种通过电解富集和液体闪烁计数（LSC）测定空气沉淀中氚的方法。氚活度是用西里西亚大学的tri -碳水化合物5110TR计数器测量的。采用142bq /g的氚水（2019年6月11日）进行校准。此外，对来自Almera 2023和ICHTJ 2023的三个水样进行了分析。通过实验验证了该方法的有效性。1.1 Bq/kg的检测限，实现精确的环境监测。该研究展示了2023年2月在波兰克拉科夫收集的降水中的氚活性。
