Environmental Protection Agency (EPA) has designated January as National Radon Action Month, a time when state radon programs and other partners conduct special radon outreach activities and events across the country. The aim of the initiative is to increase the public's awareness of radon, promote radon testing and mitigation, and advance the use of radon-resistant new construction practices.

In 2005, The U.S. Surgeon General Richard H. Carmona warned the American public about the risks of breathing indoor radon by issuing a national health advisory. The advisory is meant to urge Americans to prevent this silent radioactive gas from seeping into their homes and building up to dangerous levels.

“Indoor radon is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the county,” Carmona said. “It's important to know that this threat is completely preventable. Radon can be detected with a simple test and fixed through well-established venting techniques.”

Radon is an invisible, odorless and tasteless gas, with no immediate health symptoms, that comes from the breakdown of uranium inside the earth. Simple test kits can reveal the amount of radon in any building. Those with high levels can be fixed with simple and affordable venting techniques. According to U.S. EPA estimates, one in every 15 homes nationwide have a high radon level at or above the recommended radon action level of 4 picoCuries (pCi/L) per liter of air.

Radon gas in the indoor air of America's homes poses a serious health risk. More than 20,000 Americans die of radon-related lung cancer every year. Millions of homes have an elevated radon level. If you also smoke, your risk of lung cancer is much higher. Test your home for radon every two years, and retest any time you move, make structural changes to your home, or occupy a previously unused level of a house. If you have a radon level of 4 pCi/L or more, take steps to remedy the problem as soon as possible.

“Americans need to know about the risks of indoor radon and have the information and tools they need to take action. That's why EPA is actively promoting the Surgeon General's advice urging all Americans to get their homes tested for radon. If families do find elevated levels in their homes, they can take inexpensive steps that will reduce exposure to this risk,” said Jeffrey R. Holmstead, assistant administrator, Office of Air and Radiation, U.S. EPA.

“Based on national averages, we can expect that many of the homes owned or financed by federal government programs would have potentially elevated radon levels. The federal government has an opportunity to lead by example on this public health risk. We can accomplish this by using the outreach and awareness avenues we have, such as EPA's Web site, to share information and encourage action on radon to reduce risks,” said Edwin Pisero, Federal Environmental Executive, Office of the Federal Environmental Executive.

A national Public Service Announcement (PSA) that was released to television stations across America is reinforcing this recently updated health advisory. In the television spot, the camera scans a neighborhood with rooftop banners that remind the occupants of the importance to test their homes for radon.

These spots feature Fuad Reveiz, a member of the National Association of Home Builders and former NFL Pro Bowl place-kicker.

“It's simple and cost-effective to build new homes with radon-resistant features,” said Reveiz. “It makes sense to do it right from the start.”
