Excerpt: Gold (Au) has one stable isotope, Au, and 18 radioisotopes with Au being the most stable with a half-life of 186 days. Gold has been proposed as a material for creating a salted nuclear weapon (cobalt is another, better-known salting material). A jacket of natural Au, irradiated by the intense high-energy neutron flux from an exploding thermonuclear weapon, would transmute into the radioactive isotope Au with a half-life of 2.697 days and produce approximately .411 MeV of gamma radiation, significantly increasing the radioactivity of the weapon's fallout for several days. Such a weapon is not known to have ever been built, tested, or used. The highest amount of Au detected in any United States nuclear test was in shot "Sedan" detonated at Nevada Test Site on July 6, 1962. Standard atomic mass: 196.966569(4) u
