The Indoor Air Quality division of the US Environmental Protection Agency (EPA) presents this Web page dedicated to information about radon, the colorless and odorless radioactive known to cause lung cancer. In addition to general resources on radon (including a guide to reducing radon levels in the home), visitors will find information on how to obtain a free educational video (Breathing Easy: What Home Buyers and Sellers Should Know About Radon) recently released by the EPA. Geared primarily toward homebuyers and sellers (as well as real estate professionals), this video thoroughly reviews radon science, lung cancer risk, home inspection, how to build a new home radon-resistant, and more.
