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 100-mile-long bloom of red tide is floating off Southwest Florida, prompting warnings about respiratory irritation and potential fish kills on area beaches.
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 ...
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.
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]
Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226 .
), which is the most common naturally occurring isotope of uranium. It undergoes alpha decay to radon-222, which is also radioactive; the decay chain ultimately terminates at lead-206. Because of its occurrence in the 238 U decay chain, 226 Ra exists naturally at low concentrations in uranium-containing minerals, soil, and groundwater. [3]
Likely due to the confusion of crocodiles with alligators, many people think the species is more prevalent in the U.S. than they are. The fact is that crocodiles only exist in Florida.
