固体■比放射性测定,目前尚无统一方法,国内多采用通用的方法,即列沃奇金介绍的方法。由于该法要做自吸收校正,为此,要对样品做全分析工作,因而不仅程序复杂,而且误差较大,对一般厂、矿进行监测是不方便的。为寻求一个简便,快速,比较准确的方法,我们采用了内标准法进行了一些试验,试验证明内标准法是切实可行的。 Solid-specific radioactivity determination, there is no uniform method, the domestic use of a common method, that is, the method described by Levitch Kim. As the law to do self-absorption correction, therefore, to do a full analysis of the sample work, which not only complicated procedures, but also larger errors on the general plant, mine monitoring is not convenient. In order to find a simple, rapid and accurate method, we have carried out some tests using the internal standard method, and the test proves that the internal standard method is practicable.
