Comparison of Working Level Ratios in Houses Occupied by Smokers and Non-Smokers

摘要

The equilibrium ratios of measured radon concentrations and working levels in sixty-eight homes in Butte, Montana, were cataloged according to smokers and non-smokers in each home. The ratios were statistically evaluated to determine if there were differences in the average of the ratios depending on the number of smokers in the homes. The equilibrium ratio was higher in homes with smokers compared to homes with no smokers. This ratio was independent of the number of people smoking within the home.
