What is the Health Risk of Radon? ... articles If you live in certain parts of the United States, you might be aware of the threat that radon gas poses. Radon gas is radioactive, and in tightly insulated houses it can accumulate to concentrations that pose a health threat. If you inhale the gas into your lungs, its decay can increase your chance of getting lung cancer. A study reported in 1990 by the National Safety Council estimated that about 14,000 deaths a year could be attributed to radon, and that the number could range from 7,000 to 30,000.

A main theme of Radon is exchanging ideas amongst artists of diverse geographic and philosophical backgrounds and creating promotional support for the results of these collaborations. There is no exact membership to the collective. A distinct group of individuals has been active since the beginning, though always striving to be undefined and all inclusive. Over time, Radon has naturally extended to and overlapped with a multitude of international co-conspirators, many of whom with their own organizations. The primary divisions of Radon are a booking and promotions agency, an association of recording studios and a label offering releases on cd and vinyl.

Newsroom Florida Radon Program TEST YOUR HOME TODAY: Radon is the second leading cause of lung cancer in the U.S. after smoking, and the leading cause of lung cancer among non-smokers. The Florida Department of Health is working with the U.S. Environmental Protection Agency (EPA) in a nationwide campaign to educate Americans about the dangers of radon exposure and to encourage them to take action to protect their homes and families. Special Information for Private Schools Completing the DEO Scholarship Compliance Form. Radon is a naturally occurring, invisible, odorless, tasteless gas that is found at low concentrations in outdoor air, but which can reach harmful levels when trapped in buildings. Scientists have long been concerned about the health risk of radon, but never before has there been such overwhelming proof that exposure to elevated levels of radon causes lung cancer in humans. The U.S. Environmental Protection Agency estimates that radon is responsible for more than 21,000 lung cancer deaths per year. For more information call 1-800-543-8279.

Related News Join a Discussion More from Health To heighten awareness of that potential danger, the agency has designated January as National Radon Action Month. Radon is the second leading cause of lung cancer behind smoking, and about 20,000 people in the United States will die this year due to breathing too much radon without even knowing it, the EPA said. "It's remarkably easy to protect our loved ones by testing for radon and building new homes with radon-resistant features that allow everyone to breathe freely and safely," EPA Deputy Administrator Marcus Peacock said in a prepared statement.

Discovered : by F.E. Dorn in 1900. Isolated in Halle, Germany Origin : The name is derived from radium. Description : Radon was first discovered as the gas produced from radium as it decayed in sealed ampoules. It is colourless and odourless, and is chemically inert, but it is dangerous because it gives off alpha rays. There is a detectable amount in the atmosphere, and concentrations can build up indoors in certain localities. Image : Radon home. Click here to see larger version of this image.

Together with Ernest Rutherford (1871-1937), also teaching at McGill University, he studied this phenomenon and they observed that "the radiation from thorium oxide was not constant, but varied in a most capricious manner." whereas "all the compounds of Uranium give out a radiation which is remarkably constant"
