The costs for HG treatment exceed $3 billion for HG each year in the US, and many get inadequate care. However, the rarity of 196Hg and the high energy requirements of nuclear reactions "knocking out" a neutron from 198Hg (either via photodisintegration or via a (n,2n) reaction involving fast neutrons), have thus far ruled out practical application of this "real philosopher's stone".
