Abstract
To elucidate any connection between high Rn concentrations and low-infiltration houses, the 222Rn concentration and the infiltration rate was measured in USA houses. Three housing surveys were undertaken: 1 in energy-efficient houses located throughout the USA and 2 in conventional houses in the San Francisco area and in Maryland. In each group surveyed, no clear correlation was observed between 222Rn concentrations and infiltration rate, although each parameter varied over a wide range. Infiltration rates for the entire sample, 98 houses, ranged between 0.02-1.6 air changes/h, and 222Rn concentrations ranged from 0.1-27 pCi/l. The major cause of the observed differences in 222Rn concentration was variation from 1 house to another in the rate at which 222Rn entered houses from its sources.
