    check isotope 197 Au on wikipedia

    look inside

    stable nucleotide

    I guess maybe what if Fort Knox was glassed?

      both 198Au and 199Au have half-life in order of 3d, waiting 1y will decrease radioactivity to nothing (5E40 times for 198Au and 1.3E35 times for 199Au. others are shorter-lived and fission products can be probably separated chemically to an acceptable degree). it’s also pretty decent deterrent against stealing it, and decay product mercury is stable and easily separated. i’m not even sure if irradiating gold with neutrons would make it worthless because of that. might even go up in value because there’s now a story behind it. bigger problem would be that it’s scattered everywhere
