Soil radon survey was conducted in search for hidden and blind sandstone-type uranium deposits in SNT area of Eren basin in order to minimize blindness of borehole layout in prospecting for ore deposits and realize fast evaluation in northern China. Six radon anomalies of certain sizes were delineated in the survey area on the basis of statistic processing of radon survey data. Three potential sectors were forecast by radon anomaly appraisal combined with geological, geophysical and geochemical conditions in the area, with sandstone-type uranium mineralization found through drilling in one of the sectors, which shows that the soil radon survey is effective and feasible in search for hidden and blind sandstone-type uranium deposits in Cenozoic and Mesozoic basins of northern China.
