You say "deaths". Do you mean a 100 to 500 people will drop dead
instantly? ... NO !!! They will only die a little sooner.
The real comparison should be made using the costs in "years per
person". However not all years in a life are worth the same.
I guess, for most people, the last years of their life (as an
elderly person) are worth less than the years when in their prime
health. And damage by radioactive causes will most likely result in
cancer at an old age. This all makes the potential cost of the treat
even smaller.
(( And for people with vision, cancer (but not a brain tumor!!) will
be much less disastrous than a stroke, because you should still
be able to cryonically suspend your brain undamaged. Naturally,
this cannot be used as a hard argument to the general
(non-extropian) public. ;-<<< ))
