摘要

There are 110 million people in Sichuan Province, China. Although most of the people in cities of Sichuan use river water, which contains low levels of radon, as potable water, people in countryside and in some communities of big cities still use well water as domestic consumption. This paper reports the radon concentrations in well water investigated in four cities, i. e. Chengdu, Chongqing, Leshan and Leijiang in Sichuan Province. Of the 80 wells investigated, the radon concentrations range from 3.5 to 181.6 KBqm~(-3). Of the four cities, Chongqing has the highest well water radon concentration with the average 49. 6 ± 54.1 KBqm~(-3) and the greatest variation. The investigation in four cities showed that the radon concentrations in well water are much higher than that in tap - water. In Chongqing where there are complex geological structures, mainly granite stratum, for example, the average radon concentration in well water is 112 times higher than that in the tap - water, and even much higher than that in river water in Yangtse River, Jialing River, Jinsha River and Mingjiang River. The population in four cities is about one sixth of the total population in Sichuan Province. Because of the common use of well water and the high radon concentrations in well water in Sichuan Province, the health effect of radon in well water to the public should be stressed.
