本文件规定了一种通过液体闪烁计数测定海水、地表水、地下水、雨水、饮用水或废水中氚水（[3H]H2O）样品中氚活性浓度的方法。 该方法不直接适用于有机结合氚的分析；它的决心 需要对样品进行额外的化学处理（如化学氧化或燃烧）。 在合适的技术条件下，检测限可低至1Bq·l- 1.氚活性 低于106Bq·l-1的浓度可在不进行任何样品稀释的情况下测定。交叉引用:ISO/IEC指南98-3ISO 5667-1ISO/IEC 17025ISO 5667-3ISO 80000-10ISO/IEC指南99ISO 5667-11ISO 11929ISO 19361EPA-600/4-80ISO 5667-8ISO 5667-6ISO 7870-2ISO 5667-9ISO 5667-10ISO 5667-7ISO 5667-5ISO 5667-4IAEA GSG-2ISO 5667-20EPA-520/5-84ISO 5667-14购买本文件时可提供的所有现行修订版。

This document specifies a method by liquid scintillation counting for the determination of tritium activity concentration in samples of marine waters, surface waters, ground waters, rain waters, drinking waters or of tritiated water ([3H]H2O) in effluents. The method is not directly applicable to the analysis of organically bound tritium; its determination requires additional chemical processing of the sample (such as chemical oxidation or combustion). With suitable technical conditions, the detection limit may be as low as 1 Bq·l-1. Tritium activity concentrations below 106Bq·l-1can be determined without any sample dilution.Cross References:ISO/IEC Guide 98-3ISO 5667-1ISO/IEC 17025ISO 5667-3ISO 80000-10ISO/IEC Guide 99ISO 5667-11ISO 11929ISO 19361EPA-600/4-80ISO 5667-8ISO 5667-6ISO 7870-2ISO 5667-9ISO 5667-10ISO 5667-7ISO 5667-5ISO 5667-4IAEA GSG-2ISO 5667-20EPA-520/5-84ISO 5667-14All current amendments available at time of purchase are included with the purchase of this document.
