The hot springs were named after the radioactiveelement when an analysis of the water showed that it contained small traces of radon which is a decay product of radium. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These examples are from corp...
DU is less radioactive than natural uranium because it has less U-235 per unit of mass. All traces of decay products have been removed during the chemical purification of uranium prior to enrichment. DU can be disposed of as low-level radioactive waste or used in the fabrication of mixed ...

It decays into different particles even when it is synthesized in the lab due to its radioactive nature. Is astatine solid liquid or gas? At room temperature and atmospheric pressure, astatine is a solid. This element melts and transitions to the liquid phase at 300C. It enters the gas ...
It is produced by the radioactive decay, or breakdown, of uranium and other unstable elements. Actinium can also be artificially produced. When radium is bombarded with neutrons, some of the neutrons become part of the nucleus. This increases the atomic weight and the instability of the radium...
Helium is also formed from alpha-particle decay of radioactive elements such as uranium and thorium. It is considered a nonrenewable resource on Earth. CHARACTERISTICS Helium is a colorless, tasteless, odorless, non-toxic, and unreactive noble gas. ...
After falling to Earth, atmospheric shielding protects the meteorite fragments from further Al-26 production, and its decay can then be used to determine the meteorite's terrestrial age. Meteorite research has also shown that Al-26 was relatively abundant at the time of formation of our planetary...
A familiar use of some fluoride compounds is in toothpastes. Studies show that small amounts of fluorides can help reduce tooth decay. Fluorides are deposited as new tooth material is formed, making it strong and resistant to decay. Some cities add fluorides to their water supply. By doing ...
