自1981年以来,我大队在内蒙古中部地区开展了大面积的放射性水化学区域调查。最初,少数同志认为在内蒙古地区不适合开展该项工作,其原因有两个:一是气候干燥,水源露头少;二是该方法很少用于大面积的区调之中,难以达到预期效果。通过几年来在上述地区的实践,表明该方法在干旱、半干旱地区仍能取得一定的效果,为进一步部署普查工作,提供了依据。 Since 1981, our group conducted a large-scale radioactive hydrochemistry survey in central Inner Mongolia. Initially, a few comrades considered it inappropriate to carry out this work in Inner Mongolia for two reasons. First, the climate was dry and there were few water outcrops. Second, the method was seldom used in large area adjustments and was not able to achieve the desired results . After years of practice in the above areas, this method shows that the method can still achieve some results in arid and semi-arid areas and provides the basis for further deployment of the census.
