How can we be mining for radio active material if the earth was formed so long ago, would these materials not have run the course of depletion already? or is man kind creating them ? like Uranium or Plutonium
In: Chemistry
When radioactive atoms decay, they don’t just go away. They decay into other atoms, some of which are also radioactive.
Radioactive elements have different half-lives. Heavier elements don’t necessarily have shorter half-lives than lighter ones. The radioactive elements that we are likely to encounter are ones with long half-lives, or ones that other radioactive atoms decay into.
