Radon is formed as part of the normal radioactive decay chain of uranium. uranium has been around since the Mars was formed and its most common isotope has a very long half-life (4.5 billion years), which is the amount of time required for one-half of uranium to break down. uranium, radium, and thus radon, will continue to occur for millions of years at about the same concentrations as they do now. thumb|right|300px Radon, manchmal auch Rodan genannt, ist ein fliegendes, prähistorisches Monster, das Auftritte in mehreren Godzilla-Filmen hat.

Radon is an enemy in Final Fantasy Dimensions. Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as an indirect decay product of uranium or thorium. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It is also the only gas under normal conditions that only has radioactive isotopes, and is considered a health hazard due to its radioactivity. Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known.

n47:abstract

Radon is created by the natural breakdown of uranium in soil and rocks. While it is found all over the U.S. and in many other parts of the world, some places produce more than others. But results in your home can be different than your neighbors. Homes with basements or underground sections with more exposure or enclosure within the ground and less circulation are more likely to be at risk. But radon can enter a home in many ways: cracks in the foundation or walls, gaps in the floor or around pipes, well water and other ways. Radon doesn't have any perceptible signs. And it's fairly common. It's also a danger that you can reduce if you know about it. So, it makes sense to test for it. When you move into a new home, request a test. If you may be moving soon, you may wish to have a test you can show potential buyers. Homes are now sometimes built with radon reducing features, but even those homes should be tested initially. You can have a test done professionally, or there are kits sold by mail order and in places like hardware stores or department stores with home hardware sections. Follow the directions on the kit. (The one I used had you hang two collectors in different parts of the basement for a few days.) Different kits can take differing amounts of time -- from two day tests to months. Then you send in the kits for testing. Results are reported in pCi/L (picocuries per liter of air) or Becquerel (Bq). The lower the number, the safer. Levels of .4 pCi/L are normal outdoors; 1.3 pCi/L is considered normal for indoors. Between 2 and 4 pCi/L, the U.S. Environmental Protection Agency (EPA)[1] recommends you consider methods of reducing it. At levels above 4 pCi/L, they recommend taking steps to reduce the radon. The United Nations' World Health Organization (WHO) says than 5 and 15 Bq/m3 (Becquerel per cubic meter) is the normal range for outdoors. It is the second leading cause of lung cancer and the cause of 3-14% of lung cancer depending on other factors depending on the region of the world.[2] WHO says that countries recommend remediation at levels of 200–400 Bq/m3. The U.S. Environmental Protection Agency (EPA) suggests retesting after awhile if the levels are borderline or about every two years if you've had a problem to check on remediation measures taken. Radon is estimated to be responsible for about 20,000 lung cancer deaths in the U.S. each year. Your risk is even higher if you are also a smoker. Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as an indirect decay product of uranium or thorium. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It is also the only gas under normal conditions that only has radioactive isotopes, and is considered a health hazard due to its radioactivity. Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known. Radon is formed as one intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Thorium and uranium are the two most common radioactive elements on earth; they have been around since the earth was formed. Their naturally occurring isotopes have very long half-lives, on the order of billions of years. Thorium and uranium, their decay product radium, and its decay product radon, will therefore continue to occur for tens of millions of years at almost the same concentrations as they do now. As radon itself decays, it produces new radioactive elements called radon daughters or decay products. Unlike the gaseous radon itself, radon daughters are solids and stick to surfaces, such as dust particles in the air. If such contaminated dust is inhaled, these particles can stick to the airways of the lung and increase the risk of developing lung cancer. Unlike all the other intermediate elements in the aforementioned decay chains, radon is gaseous and easily inhaled. Thus, even in this age of nuclear reactors, naturally-occurring radon is responsible for the majority of the public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Despite its short lifetime, some radon gas from natural sources can accumulate to far higher than normal concentrations in buildings, especially in low areas such as basements and crawl spaces due to its heavy nature. It can also be found in some spring waters and hot springs. Epidemiological studies have shown a clear link between breathing high concentrations of radon and incidence of lung cancer. Thus, radon is considered a significant contaminant that affects indoor air quality worldwide. According to the United States Environmental Protection Agency, radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the United States. About 2,900 of these deaths occur among people who have never smoked. While radon is the second most frequent cause of lung cancer, it is the number one cause among non-smokers, according to EPA estimates. thumb|right|300px Radon, manchmal auch Rodan genannt, ist ein fliegendes, prähistorisches Monster, das Auftritte in mehreren Godzilla-Filmen hat.
