It emits via radioactive decay. There are three processes of radioactive decay, which are gamma, alpha, and beta. Radioactivity occurs in an unstable substances. When the substance has unstable nuclei, it is considered to be radioactive.
Why is radioactive decay so predictable? What is conserved in beta plus decay? What is the alpha decay energy for curium-247? Plutonium-239 alpha decay yields How do you calculate beta decay? Why is alpha radiation the least penetrating?
radioactive decay in nuclear reactors and Earth’s crust, and experiments inparticle accelerators. As they move, neutrinos can switch between three types, or “flavors,” in a process that continues to intrigue researchers.
The term half-life is appropriate due to the exponential and quantum nature of radioactive decay, which makes it impossible to predict exactly when a single atom of radioactive material will disintegrate. The half-life measurement instead relates to statistics, representing the time it takes for ...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
Pure hydrogen-based fuels generate radioactive decay products. Although much shorter in half life compared to nuclear fission reaction ones, they nevertheless require careful management of the wastes. Yet Another Way Almost out of left field there has been yet another arm of research into nuclear ...

It is released during the natural radioactive decay of heavier elements such as Uranium 238 and seeps through the soil into the air. Outdoors, the amount of Radon gas in the air is harmless – even in areas such as Cornwall where local geology means that more of the gas is present, out...
According to this study, in addition to heating caused by radioactive decay from unstable elements, KREEP-enriched material on the lunar surface has lower melting points. This only added to expected geologic changes. The combined results of this study suggest that KREEP-enriched maria have been ch...
Why are dinosaurs' bones radioactive? Why are fossils never found in igneous rocks? Why is radioactive decay important? Why is potassium-argon dating useful? Why do very few organisms become fossils? Why is hydroxyapatite paleontology? How is beta decay relevant to geology?
