> sterilizations of anything he comes into contact with. Previous

> the gold standard -- they can't be blocked (except by massive amounts
> of shielding) and when absorbed by the elements in the nanomachinery
> they ultimately cause transmutation which changes the element
> bonding properties which of course breaks the nanomachinery. Since
> Eliezer now has a robust defense against nanomachinery, he can now
