Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Jan. 18—ATHENS — January is National Radon Action month, and each year University of Georgia Cooperative Extension sponsors a poster contest for students across the state to help bring ...
A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
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.

The ore was mined from the Paradox Valley in Colorado [2] and other "Undark mines" in Utah. [3] As a defense contractor, USRC was a major supplier of radioluminescent watches to the military. Their plant in Orange, New Jersey, employed as many as 300 workers, mainly women, to paint radium-lit watch faces and instruments, misleading them that it ...
[31] Radon reacts with the liquid halogen fluorides ClF, ClF 3, ClF 5, BrF 3, BrF 5, and IF 7 to form RnF 2. In halogen fluoride solution, radon is nonvolatile and exists as the RnF + and Rn 2+ cations; addition of fluoride anions results in the formation of the complexes RnF − 3 and RnF 2− 4, paralleling the chemistry of beryllium(II) and ...
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 is an invisible, radioactive atomic gas that results from the radioactive decay of radium, which may be found in rock formations beneath buildings or in certain building materials themselves. Radon is probably the most pervasive serious hazard for indoor air in the United States and Europe.
