摘要：

Alpha flux radiated from Rn-222, Rn-220 and progeny is the primary contributor of natural radioactivity to the inhabitants in the ambient atmosphere. The annual indoor Rn-222 and Rn-220 concentrations were found to be 85 +/- 43 and 84 +/- 36 Bq m(-3), respectively. The estimated annual indoor Rn-222 and Rn-220 concentration is below to reference value of 100 Bq m(-3) suggested by WHO. The calculated annual inhalation dose due to exposure to the alpha flux of Rn-222, Rn-220 and their progeny is well below the recommended reference level given by UNSCEAR and ICRP. The data were further checked for normalisation and found that Rn-222 and Effective Equilibrium Radon Concentration (EERC) data are not normally distributed.
