what is interesting in the atomic-weapons context is the significance of gold for uranium storage, for gold is the metal-of-choice to store highly enriched, i.e., weapons grade uranium, rather than lead. The reason? Gold is not corrosive with uranium, and hence, won’t corrupt the stock, like lead would. It is the shielding metal of choice for storing highly enriched uranium, not to mention shielding the electronic circuitry of nuclear weapons, which circuitry has to fire perfectly, and hence, has to be shielded from radiation.
