Abstract
A survey of natural radiation levels was performed in an area with the highest mortality of lung cancer in Fujian Province of China. Even though relatively high terrestrial gamma radiation was observed, the concentrations of indoor 222Rn, 220Rn and its progeny are near the same as the provincial averages. Annual arithmetic mean concentrations of indoor 222Rn, 220Rn and its progeny were 29, 184 and 0.8 Bq m −3, respectively. The public exposure to radon and thoron is estimated to be 1.2 mSv year −1, similar to the world average.
