This paper presents the results of indoor radon surveys in the Sichuan province of China. The indoor radon concentrations found using scintillation or the two‐filter method, ranged from 1.0 Bqm −3 to 170.2 Bqm −3 . The arithmetic mean concentrations of indoor radon and its progeny were 17.8 Bqm −3 and 10.8 Bqm −3 EER (2.9 m WL), respectively. A seasonal pattern of the maximum in winter and the minimum in summer was observed for radon and its progeny concentrations. The annual effective dose equivalent resulting from indoor and outdoor inhalation of radon progeny totalled 0.93 mSv. Of the 109 million people living in Sichuan, 3000‐6800 may die annually from lung cancer induced by the inhalation of radon progeny.
