广东省居民肺癌与吸入氡关系的初步探讨

Lung cancer and ^(222)Rn inhalation in Guangdong inhabitants

本文引用我所1985年对本省居民住宅内、外氡(气土)及其短寿子体浓度调查数据及1982年全省居民人口普查统计资料,采用挪威学者Stranden氏提出的氡与肺癌关系的估算模式,对广东省居民肺癌与吸入氡及其子体的关系进行了分析讨论,得出全部肺癌发病因素中由暴露氡所致份额为11.3%。

The data used in this study were from the monitoring works on the indoor and outdoor concentration of ^(222)Rn, ^(220)Tn and their short-life daughters by our institution in 1985, and the census of this province in 1982. A mathematical model of relationship between ^(222)Rn and lung cancer, proposed by Norwegian schoolar, Stranden was used for assessment. The result suggested that the role played by the ^(222)Rn exposure would constitute 11.3% among all factors inducing lung cancer.
