摘　　要：从我国和有些国家发表的有关及其子体的数据看，其产生的剂量可能比现在估算的世界平均值高。在加强研究氡及其子体浓度水平的同时，注意研究及其子体对居民产生的照射是必要的。由于中国、日本，可能还有其它亚洲国家人口占世界人口的比例较大，对世界天然本底数值也会产生一定影响。从辐射防护角度看。Data on Radiation exposure of thoron and its progeny published in Chinese and Japanese references is possiblely higher than the world average value.While strengthening scientific research of radon and its progeny,it is also necessary to pay attention to radiation exposure of population to thoron and its progeny.The population number of China and Japan,as well as other Asian countries,accounts for a large proportion of the world population,thus having an effect on global natural background radiation to a certain extent.For the purpose of radiation protection,necessary attention should be paid to this aspect.
