对于稀土金属产品的总α总β放射性测定，采用一般分析方法前期制样难度大，不易达到制成样品源的粒度。本法通过将稀土金属产品制成削状，用适量盐酸和硝酸低温加热溶解，再加入硫酸蒸干使试液中残渣最后形成硫酸盐，通过研磨混匀的方式，制成满足有效厚度且少于最大取样量的样品源，从而实现总α总β放射性的测量。

The sample preparation for determination of total radioactivity (α+β) for a rare earth metal product is difficult. This paper puts forward a method which makes up the sample into irregular thin slice and dissolves the sample by an appropriate amount of hydrochloric acid and nitric acid. Then, adding sulfuric acid into the solution makes sulfate precipitated which is prepared into the detected sample in order to determineα+βradioactivity.
