Radon is a decay product of uranium-238 and radium-226 that is widely distributed in rock, soil, and groundwater. From: Clinics in Chest Medicine, 2021 Featured on this page Chapters and Articles You might find these chapters and articles relevant to this topic. Uranium, Plutonium, and Rad...

Uranium-235 undergoes spontaneous fission during radioactive decay; however, no standard equation can represent this reaction as its results are quite unpredictable. Uranium-235 Decay Chain The decay chain of this radioactive metal is known as theActiniumSeries with thorium-231 being the next isotope...
Recent Examples on the WebElements likeuranium 238, which has a half-life of 4.5 billion years, let geologists determine the age of rocks and meteorites; those that decay over thousands of years, like carbon-14, help date archaeological artifacts and human remains.— ...
decay varies between 159,200 and 4.5 billion years for different isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143...
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 ...
A drawing of what was deemed a “deer pig” was also sent through the uranium decay ringer. From The Daily Beast He referred to this risky state of affairs as “the babushka-with-uranium-in-the-chicken-shed” problem. From The Daily Beast It's not controllable enough and uranium isn't...

Eliminating that excuse, or at least making it statistically implausible, is the idea behindthis radioactively random dice roller. It comes to us from [Science Shack] and uses radioactive decay to generate truly random numbers, as opposed to the pseudorandom number generators baked into most micr...
In the process, fuel rods, which have been stored for a time to allow short-lived radionuclides to decay, are dissolved and the resulting solution is chemically purified and separated into wastes of different composition and activity. Routine releases from the plants to the environment occur under...
