利用放射性测量方法对大量不平衡矿石进行分析时,测定铀含量的计算工作是相当繁重的。在作大量样品分析时,为了避免根据公式进行复杂的计算,可以采用诺模图,借助此种图解能获得足够精确的结果。根据γ-测量数据 Aγ通过诺模曲线确定铀当量含量所用的公式
The calculation of uranium content is quite time-consuming when using radioactive measurements to analyze a large number of unbalanced ores. In order to avoid complex calculations based on formulas when using a large number of sample analyzes, a nomogram can be used with which accurate and accurate results can be obtained. The formula used to determine uranium equivalent content from the nomogram according to the γ-measurement data Aγ
