近年来广泛采用闪烁γ能谱法来确定矿石、晕圈和扩散流中铀(按镭)、钍和钾的含量。但是缺少成批生产的,并能确保测量精度的专用仪器。1963年A.K.阿甫契夫等已指出,在储量计算时,确定铀、钍含量的相对误差应不大于±10％。采用本文所述的Cs~(137)γ基准源稳定闪烁γ测井谱仪能量标度的电子跟踪线路比较容易达到所要求的测量精度。
In recent years, flicker gamma spectrometry has been widely used to determine the contents of uranium (by radium), thorium and potassium in ores, halo and diffusion streams. But the lack of mass production, and to ensure the accuracy of the special instrument. In 1963 A.K. 阿夫芙契夫, etc. have pointed out that in the calculation of reserves, determine the relative error of uranium, thorium content should not exceed ± 10%. It is relatively easy to achieve the required measurement accuracy by using the electronic tracking circuit of the Cs ~ (137) γ reference source stable scintillation gamma spectrometer energy scale described in this paper.
