摘要：

Inhabitants of Ramsar, a city in northern Iran, are exposed to levels of natural radiation as high as 55-200 times higher than the average global dose rate. Furthermore, radon levels in some regions of Ramsar are up to 3700 Bq m(-3). To assess the association between the radon concentration and frequency of lung cancer, lung cancer patients recorded over the past 2 years in eight districts of Ramsar with different levels of radon were studied. Data from the Ramsar Health Network show that both crude lung cancer rate and adjusted lung cancer rate in one district with the highest recorded levels of external radiation and radon concentration are lower than those of the other seven districts. It can be concluded that lung cancer rate may show a negative correlation with natural radon concentration. (c) 2004 Elsevier B.V. All rights reserved.
