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.
Water, oil and gas from a well often contain radon. The radon decays to form solid radioisotopes which form coatings on the inside of pipework. In an oil processing plant the area of the plant where propane is processed is often one of the more contaminated areas of the plant as radon has a similar boiling point to propane. [14]
If it is suspected that a private well or drinking water may be affected by radon, the National Radon Program Services Hotline at 1-800-SOS-RADON can be contacted for information regarding state radon office phone numbers. State radon offices can provide additional resources, such as local laboratories that can test water for radon. [109]
A number of spas that treat visitors with naturally infused radon water from the local hills were founded in 1906 and onwards in Jáchymov, Czech Republic, and still exist today. [6] These spas were world-renowned, as evidenced by an article in the New Zealand Thames Star Supplement from 1912 (the article uses the Austrian name of the town ...
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 .
The most prevalent radioactive gas detected was Radon, a noble gas that has no odor, no color, and no taste, and can also travel into the atmosphere or bodies of water. [8] Radon is also directly linked to lung cancer , and is the second leading cause of lung cancer in the populace.
Radium and radon are in the environment because they are decay products of uranium and thorium. The radon (222 Rn) released into the air decays to 210 Pb and other radioisotopes, and the levels of 210 Pb can be measured. The rate of deposition of this radioisotope is dependent on the weather.
The public needs to be aware of radon risks and the means to reduce and prevent these." [ 2 ] In 1996 [ citation needed ] , WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication .
