摘要
氡气灾害是一种广泛分布的地质灾害。室内氡气浓度偏高会使居民患肺癌的几率增高,而室内氡气主要来自房屋地基所在的地质单元。笔者在美国犹他大学研究所工作期间,研究了瑞丁普朗花岗片麻岩带近地表氡的浓度与铀含量的关系以及铀的分布与居民癌症死亡率之间的相关关系。铀的区域性分布是利用航空伽马能谱测量资料求得的,说明利用航空伽马能谱测量资料开展氡气灾害区域评价的可能性。文中还举例说明氡气调查在制定建设规划方面的作用。
Recent studies indicate that radon hazard is a widespread geological hazard. High radon concentrations in houses may cause lung cancer, and indoor radon comes primarily from the geological unit on which houses sit. Taking for example the Reading Prong granitic gneiss belt in the eastetn U. S., the author, while working in the U. S., studied the relationship between nearsurface radon and uranium concentrations as well as the correlation between ground uranium distribution and cancer mortality of residents. The regional uranium distribution was mapped by using airborne gamma-ray spectre-metric data. As a result, the applicability of airborne gamma-ray spectrometric data to regional evaluation of radon hazard has been suggested. A case history on Antelope Island in the Great Salt Lake, Utah, is also presented, showing the role of radon surveys in construction planning.
