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 ...
Gentry noted that the 218 polonium radio halos only formed at temperatures below 300 degrees and were visible for less than 3 minutes, thus requiring the Precambrian granites where they are to have formed by a quick process yet "mysterious" [clarification needed] [13] cold, highlighting the singularities of the continental crust [14] [15] in relation to the oceanic crust.
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Radon seeps out of these ores into the atmosphere or into ground water or infiltrates into buildings. It can be inhaled into the lungs, along with its decay products, where they will reside for a period of time after exposure. Although radon is naturally occurring, exposure can be enhanced or diminished by human activity, notably house ...
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.

Bourbon Street has long been party central, and little changed in the hours after Surgeon General Vivek Murthy on Friday outlined the direct link between alcohol consumption and increased cancer risk.
In this podcast episode, Medical News Today shares three actionable resolutions that can help improve brain, heart, and metabolic health in the new year via diet, sleep, and exercise.
The film was released in 2019 on Netflix, Amazon, Vimeo, iTunes, Google Play and YouTube. The American Dental Association, American Association of Endodontists and the American Association of Dental Research sent a private letter to media companies hosting the film and warned them that "continuing to host the film could harm the viewing public by spreading long-disproven claims."
