天然产状放射性矿石的射气扩散的定量评价,对考虑该因素对辐射取样结果的影响是很必要的。在此种情况下利用粉末状矿石的射气扩散系数不能提供足够准确的结果,因为天然产状中的射气扩散值和粉末中的射气扩散值是有差别的。下面将提出一种确定数值的方法,该值能够说明由于矿石的射气扩散而造成的γ辐射强度的变化。问题的提出正如哈依科维奇所指出的(1958),在矿层被揭露之后,由于射气损失的结果,矿层的γ辐射强度
Quantitative evaluation of the gas diffusion of naturally occurring radioactive ore is necessary to consider the effect of this factor on the radiation sampling results. In this case, the use of the radio diffusivity of the powdered ore does not provide sufficiently accurate results because the emanation of emanating gas in the natural state is different from the emanation of the emanating gas from the powder. In the following, a method for determining the value of a change in the gamma radiation intensity due to the aeration of the ore will be given. PROBLEM PROBLEMS As Hayekovich pointed out (1958), after the seam was exposed, as a result of the loss of radioactivity, the gamma radiation intensity of the seam
