Abstract
A number of radon-related properties have been surveyed in underground shopping centers in Hong Kong. These parameters include the radon con centration, the total potential alpha energy concentration of radon pr ogeny, the equilibrium factor and the unattached fraction of radon pro geny. The mean values recorded for these were 29.2 +/- 7.8 Bq/m(3), 3. 60 +/- 1.53 mWL, 0.46 +/- 0.16 and 0.05 +/- 0.03, respectively. Based on these figures, we have calculated the average radon dose received b y employees in an underground shopping center in Hong Kong to be 0.22 mSv/yr, which represents an approximate increase of 8% over the total dose of about 2.7 mSv/yr received by the average person in Hong Kong.
