Ionizing Radiation in Dwellings Related to the Building Materials
Experimentally determined values were used to investigate the absorbed dose or concentration of radon and daughter products. The exposure rates, the concentrations of radon and daughter products and the ventilation rates have been determined in seven groups of houses built in the early 1970s in central Sweden. The activity concentrations in the building maerials used at the time for building the houses were measured earlier. The absorbed dose in the gonads was, as expected, found to be lower than the theoretical value, 1,5mGy/y. For the multi-family houses the values were about 1,0 mGy/y and for the single-family houses about half that value. The concentrations of radon in equilibrium with the daughter products normalized to one air change per hour and to the maximum concentration of radium-226 in the building material were found to be about 100Bq/m exp 3 , for the multi-family houses. No significant difference from this value was found for the single-family houses despite the fact that the amounts of stony building materials were less than in the multi-family houses.
