Natural radon concentrations in the Earth's atmosphere are so low that radon-rich water in contact with the atmosphere will continually lose radon by volatilization. Hence, ground water has a higher concentration of 222 Rn than surface water , because radon is continuously produced by radioactive decay of 226 Ra present in rocks.
Rainwater can be highly radioactive due to high levels of radon and its decay progenies 214 Bi and 214 Pb; the concentrations of these radioisotopes can be high enough to seriously disrupt radiation monitoring at nuclear power plants. [11] The highest levels of radon in rainwater occur during thunderstorms, and it is hypothesized that radon is ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Because atmospheric radon concentrations are very low, radon-rich water exposed to air continually loses radon by volatilization. Hence, ground water generally has higher concentrations of 222 Rn than surface water, because the radon is continuously replenished by radioactive decay of 226 Ra present in rocks. Likewise, the saturated zone of a ...

For the six-sided shape freezing water takes in nature, see snowflake. Hexagonal water, also known as gel water, structured water, cluster water, H3O2 or H 3 O 2 is a term used in a marketing scam ...
Scientists analyzed water samples flowing through eight large publicly owned wastewater plants across the US, all of similar size and using similar technologies to those serving 70% of the population.
Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies. Radon is a significant contributor to environmental radioactivity and indoor air pollution .
Radon experiments at the Radium Institute in Paris, 1924. Radon is a naturally occurring radioactive noble gas discovered in 1900 by Friedrich Ernst Dorn (1848-1916) and is considered carcinogenic. Radon is increasingly found in areas with high levels of uranium and thorium in the soil. These are mainly areas with high granitic rock deposits.
