The Convention on the Physical Protection of Nuclear Material was adopted on 26 October 1979 in Vienna, Austria. The initial signing ceremony took place in Vienna and at New York on 3 March 1980, and the convention entered into force on 8 February 1987. The convention is deposited with the International Atomic Energy Agency. In July 2005 a diplomatic conference was convened to amend the convention and strengthen its provisions, as a result of which it was renamed the Convention on the Physical Protection of Nuclear Material and Nuclear Facilities.
