Izloženost radonu u stanovima grada Zagreba

Until the 1970s radon and its progeny were regarded as radiation health hazards encountered only in the mining and processing of uranium ore. This notion has dramatically changed as a result of increasing efforts made by many countries to measure radon in dwellings. Since it has been assessed that radon constitutes on average about 53% of the human exposure to natural radiation (UNSCEAR 1993), attention to the problem of exposure to radon and associated health risk has been growing in both developed and developing countries. This paper deals with the investigations of indoor radon activity concentrations at selected dwellings in the area of Zagreb. The fact that concentration of indoor radon depends strongly on radium sources in the soil pointed to the possibility that increased radon levels could be measured in the ground floor dwellings. The measurements of indoor radon performed by Honeywell professional radon monitor in the 30 ground floor dwellings, and at same location in 10 dwellings on higher floors. In order to obtain average daily values, radon activity concentrations were measured throughout 24 hours at each dwelling, over the seasons spring-summer and autumn-winter. In the season spring-summer radon activity concentrations in the ground floor dwellings ranged from 22 ą 5 to 133 ą 12 Bqm-3 (mean value 56 ą 31 Bqm-3) and in the season autumn-winter ranged from 22 ą 5 to 311 ą 18 Bqm-3 (mean value 94 ą 64 Bqm-3). In the dwellings on higher floors radon activity concentrations in the season spring-summer ranged from 11 ą 3 to 78 ą 9 Bqm-3 (mean value 32 ą 21 Bqm-3), and in the season autumn-winter ranged from 30 ą 5 to 137 ą 12 Bqm-3 (mean value 60 ą 32 Bqm-3). Average annual radon activity concentration for the 30 investigated ground floor dwellings were 75 ą 45 Bqm-3, and 46 ą 26 Bqm-3 for the 10 dwellings on higher floors. Investigations performed in the dwellings in the area of Zagreb revealed significant differences in radon levels between the ground floor dwellings and the dwellings on higher floors.
