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. From the time of diagnosis, between 11 and 15 percent of those afflicted will live beyond five years, depending upon demographic factors. In many cases lung cancer can be prevented; this is especially true for radon.

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.

19. Radon It is essentially inert and occupies the last place in the zero group of gases in the Periodic Table. Since 1923, it has been called radon. http://periodic.lanl.gov/elements/86.html

Atomic Number: Atomic Radius: Atomic Symbol: Rn Melting Point: -71 ºC Atomic Weight: Boiling Point: -61.7 ºC Electron Configuration: [Xe]6s Oxidation States: History (From radium ; called niton at first, L. nitens : shining) The element was discovered in 1900 by Dorn, who called it radium emanation . In 1908 Ramsay and Gray, who named it niton, isolated the element and determined its density, finding it to be the heaviest known gas. It is essentially inert and occupies the last place in the zero group of gases in the Periodic Table. Since 1923, it has been called radon. Isotopes Twenty isotopes are known. Radon-22, from radium, has a half-life of 3.823 days and is an alpha emitter; Radon-220, emanating naturally from thorium and called thoron, has a half-life of 55.6 s and is also an alpha emitter. Radon-219 emanates from actinium and is called actinon. It has a half-life of 3.96 s and is also an alpha emitter. It is estimated that every square mile of soil to a depth of 6 inches contains about 1 g of radium, which releases radon in tiny amounts into the atmosphere. Radon is present in some spring waters, such as those at Hot Springs, Arkansas. Properties On the average, one part of radon is present at 1 x 10
