Plutonium-238 has also been used successfully to power artificial
heart pacemakers, to reduce the risk of repeated surgery.[83][84]
It has been largely replaced by lithium-based primary cells, but
as of 2003 there were somewhere between 50 and 100 plutonium-
powered pacemakers still implanted and functioning in living
patients.[85] Plutonium-238 was studied as a way to provide
supplemental heat to scuba diving.[86] [...]
