Indoor exposure to the naturally occurring, short-lived decay products of radon (Rn-222) inside buildings and homes may pose a significant public health problem. Estimates are that as many as 8 million residential buildings may have indoor radon concentrations that exceed the action level recommended by the U.S. Environmental Protection Agency (4 pCi.L-1). This paper examines the sources of radon in buildings and provides an overview of the methods currently available to reduce indoor concentrations of radon and its decay products.
在建筑物和住宅内，室内接触天然存在的、氡（Rn - 222）的短寿命衰变产物可能会构成重大的公共卫生问题。据估计，多达800万栋住宅建筑的室内氡浓度可能超过美国环境保护局建议的行动水平（4皮居里·升⁻¹）。本文探讨了建筑物中氡的来源，并概述了目前可用于降低室内氡及其衰变产物浓度的方法。
