Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
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]
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.

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
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.
Radon is potentially useful as an earthquake predictor because it is radioactive and thus easily detected, [f] and its short half-life (3.8 days) makes radon levels sensitive to short-term fluctuations. A 2009 compilation [59] listed 125 reports of changes in radon emissions prior to 86 earthquakes since 1966. The International Commission on ...
ONLY TAKES 2 SECONDS to share." The posts have materialized in groups as far flung as New York and Colorado, even stretching into Canada and Great Britain. And on Monday, someone posted one to ...
Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year). Radon is unevenly distributed and varies with weather, such that much higher doses apply to many areas of the world, where it represents a significant health hazard.
