本文所提出的方法用于在有不平衡的镭、钍和钾的存在情况下,对低含量铀进行放射性测定。这个方法是大家熟知的β-γ方法的进一步发展[1-3]。天然样品的β-γ强度测定结果的一般形式可以用带有四个未知数的两个方程组表示:
The proposed method is used for the radiometric determination of low-level uranium in the presence of unbalanced radium, thorium and potassium. This method is a well-known beta-gamma method for further development [1-3]. The general form of the beta-gamma intensity measurement of a natural sample can be represented by two equations with four unknowns:
