While radon is the second most frequent cause of lung cancer, it is the number one cause among non-smokers, according to EPA estimates. About 2,900 of these deaths occur among people who have never smoked. Thus, radon is considered a significant contaminant that affects worldwide.Īccording to the, radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the. Studies have shown a clear link between breathing high concentrations of radon and incidence of. It can also occur in water where the water comes from a ground source -e.g. 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 density. It is often the single largest contributor to an individual’s dose, and is the most variable from location to location. Thus, naturally-occurring radon is responsible for the majority of the public exposure to. Unlike all the other intermediate elements in the aforementioned decay chains, radon is gaseous and easily inhaled. 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 the gaseous radon itself, radon progeny are solids and stick to surfaces, such as dust particles in the air. As radon itself decays, it produces new radioactive elements called radon progeny (formerly called daughters) or decay products. Thorium and uranium, their decay product, 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. Their naturally occurring isotopes have very long half-lives, on the order of billions of years. Thorium and uranium are the two most common radioactive elements on earth they have been around since the earth was formed. Radon is formed as one intermediate step in the normal radioactive through which and slowly decay into.
Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known.
It is also the only gas under normal conditions that only has radioactive isotopes, and is considered a health hazard due to its radioactivity.
Radon is one of the densest substances that remains a under normal conditions. It is a, colorless, odorless, tasteless, occurring naturally as a of.
