Behavior of {sup 222}Rn and its progeny in high-rise buildings
- Univ. of Hong Kong (Hong Kong). Radioisotope Unit
Unlike detached or semi-detached houses, the main source of indoor radon in high-rise buildings is the building material. Radon released from the building material will be removed by ventilation, either forced or natural, so that its concentration, its progeny`s concentration, and the equilibrium between the two will be different for different types of buildings and environmental factors. A number of surveys were carried out in buildings throughout the territory to look at the seasonal variation of indoor {sup 222}Rn levels; the dependence of indoor {sup 222}Rn concentration on the living environment; the indoor gamma dose rate and its relation to indoor {sup 222}Rn concentration; and the dependence of {sup 222}Rn progeny concentration and equilibrium factor on the environment in high-rise buildings.
