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]
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 ...
The World Health Organization suggests mitigation systems starting at 2.7 pCi/L of radon in the air. The WHO’s recommendations are based on a review of research by 100 scientists from 30 countries.
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 ...
Overall, he said precipitation for this water year (which started Oct. 1) is well below average over the Southwest. Many locations in the region have been near-record dry since October. Looking ahead
Radon is a decay product of uranium, which is relatively common in the Earth's crust, but more concentrated in ore-bearing rocks scattered around the world. Radon seeps out of these ores into the atmosphere or into ground water or infiltrates into buildings.
By Gillian Pensavalle No, there's not a gigantic 50-foot crab hanging out in a small harbor town in the UK. Foiled again, Internet. Photoshop strikes again; the photo is fake. The photo made ...
