摘要：

Indoor and outdoor (222)Rn concentrations and their diurnal variations with atmospheric air pressure, humidity and temperature were studied in the southwest coast region of India using AlphaGUARD PQ-2000PRO and accessories. The indoor (222)Rn concentration varied in the range 764 Bq m(-3) with a mean value of 32 Bq m(-3), and the outdoor concentration varied in the range 3-35.2 Bq m(-3) with a mean value of 15.7 Bq m(-3). The mean annual effective doses were 0.81 and 0.1 mSv for indoor and outdoor, respectively. (c) 2004 Elsevier B.V. All rights reserved.
