Weapons grade plutonium goes missing from US university

Idaho State University was using the radioactive chemical element, which was about the size of a 10p piece, for research. The US Nuclear Regulatory Commission said the university could not account for about a 30th of an ounce (one gram) of the material, which is used in nuclear reactors and to make nuclear bombs. While the amount is too small to make a nuclear bomb, it could be used to make a dirty bomb to spread radioactive contamination, said Victor Dricks, a spokesman for the agency.
