Uranium - Wikipedia

Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and …

Feb 19, 2019· Kai Vetter, a nuclear physicist at the University of California, Berkeley, says that the danger from uranium ore exposure strongly depends on the time and distance to the radioactive material.


Uranium ore is really only a hazard if its ingested or inhaled. Keeping it in a display case should pose no problems. The ore will produce a small amount of radon gas over time from natural radioactive decay. The activity of the sample was measured at 3,500 CPM (counts per minute) using a Radeye B20 meter. ...
