Uranium U PubChem

Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air, and water, and it occurs in nature in the form of minerals but never as a metal. Uranium metal is silver-colored with a gray surface and is nearly as strong as steel.Natural uranium is a mixture of three types or isotopes called U-234/234U, U-235/235U and U-238/238U.

Uranium Radiation Properties

2021-5-1  Uranium. Uranium is a metal of high density (18.9 g/cm 3).The earth's crust contains an average of about 3 ppm (= 3 g/t) uranium, and seawater approximately 3 ppb (= 3 mg/t). Naturally occuring uranium consists of three isotopes: U-238 (more than 99%), U-235, and U-234, all of which are radioactive and have very long half-lives, i.e. decay very slowly.
