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 ...
2) and the high positive charge on radon in RnF +; spatial separation of RnF 2 molecules may be necessary to clearly identify higher fluorides of radon, of which RnF 4 is expected to be more stable than RnF 6 due to spin–orbit splitting of the 6p shell of radon (Rn IV would have a closed-shell 6s 2 6p 2 1/2 configuration). Therefore, while RnF
Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1] Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2]
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
After 11 half-lives (42 days), radon radioactivity is at 1/2 000 of its original level. At this stage, the predominant residual activity is due to the radon decay product 210 Pb, whose half-life (22.3 years) is 2 000 times that of radon, and its descendants 210 Bi and 210 Po, totalling 0.03% of the initial seed activity.

Verdict: False There is no evidence for this claim, which originates from a site Check Your Fact has debunked in the past. Fact Check: Life expectancy in the United States is on the rise again ...
The most reliable way to stop the spread is washing your hands with soap and water for at least 20 seconds, especially if you are preparing food, or after using the restroom or changing diapers.
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 .
