Summary
The health hazards associated with radon, a naturally occurring radioactive gas, may be significantly greater in buildings where ventilation is restricted. Since building materials such as concrete, gypsum, brick, and wood are potential sources of radon, it is important that their radon emanation rate be determined. A rapid and accurate method is presented for determining the radon emanation rate per mass from building materials by determining simply the radon exhalation rate per unit mass. A small sample of the material is sealed in a container from one to three days. The emanated radon is then collected on glass wool cooled to liquid-nitrogen temperature and subsequently transferred to a scintillation flask where the ..cap alpha..-activity is counted. The reproducibility errors of the measurements are on the order of 5%.
