Marshall and Marshall have examined the original papers leading to radon's discovery and their work should be consulted for a full treatment and extensive references. [8] They conclude that it is actually Rutherford who should be awarded credit for radon's discovery since he was the first to detect the element being emitted from any ...
Misleading videos and false claims that President Joe Biden wandered off aimlessly from the G7 conference last week continued to go viral despite debunkings and fact-checks that tried to correct ...
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.

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]
Two weeks after accusations of plagiarism rocked many in the YouTube community, a creator who was at the center of the controversy spawned even more backlash after he deleted an apology video ...
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
On April 2, 2021, Charles posted a video entitled "Holding Myself Accountable" on his YouTube channel, which has now garnered over 8.5 million views. In this video, he openly admitted to engaging in flirtatious conversations with two 16-year-old boys, operating under the belief that they were older.
Radon compounds are chemical compounds formed by the element radon (Rn). Radon is a noble gas, i.e. a zero-valence element, and is chemically not very reactive. The 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer. Because radon is a gas under normal circumstances, and its decay-chain parents are not, it ...
