@import url(../../styles.css); Radon Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas. It is formed by the natural radioactive decay of uranium in rock, soil, and water. Naturally existing, low levels of uranium occur widely in Earth's crust. It can be found in all 50 states. Unless you test for it, there is no way of telling how much is present.

The U.S. Surgeon General, the U.S. Environmental Protection Agency (EPA) and MDH recommend that every Minnesota home be tested for radon. Radon is not regulated in Minnesota, so it is up to homeowners to decide for themselves how much radon is acceptable in their home. The good new is, homeowners can act to lower the amount of radon in their home and reduce the risks to their family. On this page: Why is radon important? What is radon? How does radon enter a home? Major Radon Entry Routes ... Where can I get more information on radon or other indoor air quality issues? Why is radon important? Radon is the main source of ionizing radiation that most of us are exposed to. Ionizing radiation can harm the cells that make up our body's tissues and organs. The type of radiation that radon produces is mainly an internal hazard - it produces damage when it is gets into the body. The result of such damage is that radon causes cancer in humans.

UNDERSTANDING RADON by G. Thomas Martin We realize most people find it difficult to understand radon; a colorless, odorless, inert radioactive gas. You cannot see it, smell it, or feel it; yet we cannot completely avoid breathing radon. There is about 0.35 pCi/L of radon in the outside air we breathe. Understanding the risks associated with radiation exposure is even more perplexing. I hope reading this article, will enable you to make an informed decision about the radon levels measured in your house. TABLE OF CONTENTS Section 1...Where Does Radon Come From? 2...How Does Radon Get Into The House? 3...What About Radon in Well Water? 4...What About Radon in City Water? ... 15...How Can I Learn More About Radon? 1. WHERE DOES RADON COME FROM? Radon comes from the natural radioactive decay of radium and uranium found in the soil beneath the house. The amount of radon in the soil depends on complex soil chemistry, that varies from one house to the next. Radon levels in the soil range from a few hundred to several thousands of pCi/L. The amount of radon that escapes from the soil to enter the house depends on the weather, soil porosity, soil moisture, and the suction within the house. 2. HOW DOES RADON GET INTO THE HOUSE?

Radiation in your own home? What is radon? Where does radon come from? At what level is radon dangerous? Radon in the air. ... Go Back What is radon? And why are they saying all those bad things about it? Radon is a colorless, odorless gas, a radioactive byproduct of radium. It is part of the natural radioactive decay series starting with uranium-238. It is radioactive with a half-life of 3.8 days, decaying by the emission of alpha particles to polonium, bismuth, and lead in successive steps. The decay of radon-222 with emission of an alpha particle is followed within about an hour by a series of four further decays, two of them accompanied by emission of alpha particles and the other two accompanied by other types of radiation. The short-lived atoms into which a radon atom decays are actually isotopes of polonium, lead, and bismuth, but they are referred to collectively as radon daughters, or, by those sensitive to questions of gender, as radon progeny. The radon daughter atoms float around in the air during their few minutes of existence, often becoming attached to dust particles. In summary, a radon atom in the air decays within a few days into its short-half-life radon daughters, which decay within about an hour; with these decays, three alpha particles are emitted, one by radon and two by its daughters.

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. In this edition of How Stuff Works , we'll talk about what radon is, how you can find it in your home and what the health risks are for it.

The untimely deaths of Peter Jennings and Dana Reeve have raised public awareness about lung cancer, especially among people who have never smoked. Smoking, radon, and secondhand smoke are the leading causes of lung cancer. Although lung cancer can be treated, the survival rate is one of the lowest for those with cancer. In many cases lung cancer can be prevented; this is especially true for radon. Radon is the leading cause of lung cancer among non-smokers, according to the U.S. Environmental Protection Agency. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked. On January 13, 2005, Dr. Richard H. Carmona, the U.S. Surgeon General, issued a national health advisory on radon. Visit www.cheec.uiowa.edu/misc/radon.html

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.
