摘　　要：根据铀废石堆放形式 ,分析了平坦型、沿山坡堆放型、山型三类铀废石堆放场地的氡析出特征 ,得出了平坦型废石场以扩散析出为主 ,沿山坡堆放型和山型废石场既要考虑氡的扩散析出 ,还要考虑氡渗流的影响。The radon emanation characteristics of three types of uranium waste rock pile site (flat pile type,hillside pile type,hill pile type) have been analyzed.The results show that the radon exhalation is mainly from diffusion for flat pile type,while for hillside pile type and hill pile type,the radon exhalation are both from diffusion and radon permeation.The moisture of waste rock is the major factor influencing the radon emanation of three kinds of waste rock pile sites.
