摘要
散料γ射线厚度测量方法主要研究了宽束和窄束条件下,线减弱系数μ实与实验条件、散料厚度及散料含水量的变化规律,从中寻找计算散料厚度的方法,还研究了积累因子B与实验条件、散料厚度及含水量的关系。同时对实验测量的μ实与理论计算的μ理进行了比较。
he experimental values of γ ray linear absorption coefficient μexp under various experimental conditions are calculated. Various μexp values which vary with the thickness and moisture of matter in bulk under the conditions of wide and narrow γ ray beams are studied, and the measuring method of the thickness of matter in bulk is given. The μexp is compared with the μth which is obtained by theoretical calculation. In addition, the variation of the buildup factor B with the experimental conditions, such as the thickness and the moisture of matter in bulk, is studied.(
