What is uranium, and where does it come from?
Uranium is simply a metal. It’s found everywhere in the earth’s surface. It’s found at two parts per billion in the oceans. It’s concentrated, like all the metals, in deposits here and there all over the earth. It looks something like lead. It’s heavy like lead. It has a mild amount of radioactivity associated with it, but nothing like radium, for example, which is also scattered throughout the earth’s crust.
