EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES
The European Journal of Environmental Sciences offers a mixture of original peer-reviewed research papers, which bring you some of the most exciting developments in environmental sciences in the broadest sense, often with an inter- or trans-disciplinary perspective, focused on the European problems. The journal also includes critical reviews on topical issues, and overviews of the status of environmental protection in particular regions or countries. The journal covers a broad range of topics, including direct or indirect interactions between abiotic or biotic components of the environment, interactions of environment with human society, or environmental sustainability.

abstract

The concentration of radon in the air in buildings ranged from 1.87 ± 3.24 Bq/m3 to 14.27 ± 1.50 Bq/m3 with a mean of 6.31 ± 3.47 Bq/m3 while that of the progeny of radon varied from 0.007 to 0.057 WL (average: 0.025). The mean indoor concentration of radon was considerably less than the lower levels prescribed by EPA (148 Bq/m3), WHO (100 Bq/m3), EEC (400 Bq/m3), ICRP (200–600 Bq/m3) and NRPB (200 Bq/m3). The annual effective equivalent dose of indoor radon (< 0.8 mSv/y) that the bronchial and pulmonary regions of human lungs are exposed to (<0.8 mSv/y) is less than the UNSCEAR and WHO recommended global lower average dose value of 1 mSv/y. The lifetime fatality risk of exposure to the progeny of radon (PAEC) varied from 0.03 × 10−4 to 0.19 × 10−4, with an average value of 0.08 ± 0.04 × 10−4.
