Thanks. Presumably we're talking about "Dose rates at the surface of the pacemaker are approximately 5 to 15 mrem per hour from the emitted gamma rays and neutrons" though.

Yeah ideally I would not want that in or close to my body but if the choice is literally life or death I guess I'll take it.

How do modern pacemakers work? Can they be recharged inductively or is surgery required to replace batteries periodically?
