摘要：
Radon decays to a long-lived isotope Pb-210 with a half-life of about 22 years. Measuring concentrations of Pb-210 in household dust could be an alternative method of determining indoor radon levels. This novel method for estimating long-term radon concentration was explored in over a hundred Canadian residential homes. The results demonstrate that Pb-210 concentrations in household dust relate reasonably well to radon concentrations in homes.
