Behavior of 222Rn and its progeny in high-rise buildings

Health Phys. 1998 Sep;75(3):303-12. doi: 10.1097/00004032-199809000-00010.

Abstract

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 222Rn levels; the dependence of indoor 222Rn concentration on the living environment; the indoor gamma dose rate and its relation to indoor 222Rn concentration; and the dependence of 222Rn progeny concentration and equilibrium factor on the environment in high-rise buildings.
