Burnett Department of Earth, Ocean and Atmospheric Sciences, Florida State University, Tallahassee, Florida Abstract In order to evaluate groundwater discharge into small lakes we constructed a model that is based on the budget of 222Rn (radon, t 1/2 5 3.8 d) as a tracer. Radon (chemical symbol Rn) is a naturally occurring radioactive gas found in soils, rock, and water throughout the U.S. It has numerous different isotopes, but radon-220, and -222 are the most common. Radon causes lung cancer, and is a threat to health because it tends to collect in homes, sometimes to very high concentrations. High Radon‐222 (222 Rn) concentrations exist in ground water from most granitic rocks in Maine.Some values exceed the suggested limit of 500 pCi/1 (E.P.A., 1976) by more than 100 times. Although high values (x̄= 22,100 pCi/1) are conclusively linked with the granites, high values are also present in ground water in metasedimentary rocks from sillimanite‐ (x̄= 13,630 pCi/1) and Radon-222 decay chain . Radon (Rn) is an inert, radioactive gas which has several isotopes.

by Radon-222. by Radon-222. Latest Favorite Art 2020-01-18 The half-life of 222 Rn (3.82 d) is long enough for much of the gas to work its way out into the atmosphere. Radon is also generated in the other two series. However, these isotopes of radon are of lesser radiological importance. The thorium series generates 220 Rn, which is also called thoron. The chart below lists all of the decay products of radon gas (radon-222) in their order of appearance.

Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer.

Radon is a naturally occurring radioactive gas that is odorless and tasteless. It is formed from the radioactive decay of uranium. Uranium is found in small amounts in most rocks and soil.

It divides into two parts-one part is called radiation, and the other part is Radon-222, a noble gas resulting from the decay of naturally occurring uranium-238, is the first occupational respiratory carcinogen to have been identified. As early as the 1500s, Agricola chronicled unusually high mortality from respiratory disease among underground metal miners in the Erz Mountains of eastern Europe (Hoover and Hoover 1950). Radon-222 is a radioisotope of radon. Radon is a colorless, odorless, tasteless noble gas, occurring naturally as the decay product of radium.All isotopes of radon are radioactive, but the two radon isotopes radon-222 and radon-220 are very important from radiation protection point of view..
