标准摘要
[中文适用范围]： 本文件规定了使用 α 能谱法和 232U 作为产量示踪剂测定环境水（包括海水）样品中铀同位素活度浓度的条件。 需要进行化学分离来从样品的测试部分中分离和纯化铀。 [外文原描述]： This document specifies the conditions for the determination of uranium isotope activity concentration in samples of environmental water (including sea waters) using alpha-spectrometry and 232 U as a yield tracer. A chemical separation is required to separate and purify uranium from a test portion of the sample.
英文名称Water quality — Uranium isotopes — Test method using alpha-spectrometry
