本文所提出的γ辐射仪校正方法的基础是等效原理,即具有点状镭源的水-空气模型的γ射线的散射等效于平衡铀含量均匀分布的半矿层对γ辐射的散射。众所周知,用点状镭源的直射γ射线把野外γ辐射仪校正成剂量强度单位(微伦琴/小时)是一种具有极大条件性的校正[2,5]。用不同型号的辐射仪测量同样物体的γ放射性的数据是不同的。用MG型盖革-缪勒计数管测量的结果近似闪烁辐射仪的测量结果的三分之二到二分之一。如果具有百分之一平衡铀当量含量(均匀的)的矿层所造成的γ场值或用该值的导出值作为
The correction method proposed in this paper is based on the principle of equivalence. That is, the γ-ray scattering from a water-air model with a point-like laser source is equivalent to the scattering of γ radiation from a semi-seam with a uniform distribution of uranium content. It is well-known that the correction of field gamma-ray radiometers to dose-intensity units (microloren / hr) with direct gamma radiation from point-shaped radium sources is a conditionally correct correction [2,5]. Using different types of radiometers to measure gamma radioactivity of the same object is different. The results of the MG Geiger-Muller counter tube approximate two-thirds to one-half the results of the flicker radiometer measurements. If one hundred percent of the γ field caused by a layer of ore with a balanced uranium content (uniform) is used or the derived value of the value is taken as
