摘　　要：适宜用原地浸出工艺开发的砂岩型铀矿床大多产于厚覆盖的荒漠、戈壁、半丘陵等景观地区。简要介绍近年来在我国西北某砂岩型铀矿床上先后开展的地面γ测量、土壤铀金属量测量、地气(铀)测量、金属(铀)活动态测量、大地气态水铀测量、累积式活性炭吸附氡测量、瞬时式活性炭吸附氡测量等7种放射性测量找矿方法的试验工作及其结果。ISL amenable sandstone-type deposits often occur in the area with thick cover of wilderness, desert and hill. In recent years, seven methods of radioactive uranium exploration for sandstone-type uranium deposits have developed successively in Northwest China： ground gamma-ray survey, uranium metallometric survey in soil, geo-gas（uranium）survey, mobile forms of metals in overburdens, earth gaseous water uranium survey, survey of radon absorption by accumulated activated charcoal and survey of instantaneous absorbed radon by activated charcoal. The experimental circumstances and results are introduced briefly in the paper.
