We describe an advanced methodology for low-level tritium measurement in regard to calibration, electrolytic tritium enrichment, liquid scintillation counting (LSC) measurement, and prevention of sample contamination. Details are given on enrichment parameters and electrode processes for optimisation of enrichment reproducibility and on optimisation of LSC stability. Intercomparison results demonstrate high accuracy of the tritium measurement system. The use of accurate tritium data for groundwater dating in the southern hemisphere is demonstrated with data from several groundwater systems of New Zealand.
我们描述了一种用于低水平氚测量的先进方法，涉及校准、电解氚富集、液体闪烁计数（LSC）测量以及样品污染的预防。给出了关于富集参数和电极过程的详细信息，以优化富集的可重复性，以及关于LSC稳定性的优化。比对结果证明了氚测量系统的高精度。利用来自新西兰几个地下水系统的数据，展示了准确的氚数据在南半球地下水年代测定中的应用。
