What is radon gas in water?

Radon is a naturally-occurring gas that is produced when the element radium decays.  Since radium is radioactive, radon itself is radioactive. When radon decays it forms the element polonium.  Polonium is also a radioactive element. It is the polonium that is produced by the radon, that gets into the air and into people’s lung.  This gas can injure lung tissue and potentially cause lung cancer. Radon itself, is usually in very small amounts in rock, soil and even becomes carried in water, air and in natural gas.  Some rock types are known to potentially produce higher-than-average amounts of radon. In the late 1990’s, the United States Geological Survey began to research the radon that has mostly been limited to groundwater.  They found the higher concentrations of the radioactive material found in water, depends on the climate which you live in. They found that the higher elevations of the gas was found in wells in the climate that have drier regions.  The climate that are more humid, have a much lower occurrence of radioactive gases in their wells. The most likely reasons for this is because it is considered ‘old’ water. Dry air, does not have as much evaporation, giving way for new water to filter up through the ground.  It is the filter through the ground, which cause the oxygenation and allows the radon gases to escape from the water system. A long standing drinking well will also have a higher concentration than that of the water that comes from purified water stations. The filtration and the natural oxygenation that comes from the water constantly moving, both  helps to contribute to lowering the radioactive attributes that are put into the category of radon gas.
