On the plus side:
"But internal emitters steadily and continuously emit radiation for as
longas the particle remains radioactive, or until the person dies –
*whichever occurs first*. As such, they are much more dangerous."
So I've got 130 Cubic metres of oil & gas NORM (~1000Bq/g) from a client to
get rid off. If we could marry that disposal operation with a friendly
state that still has the death penalty I could "neutralise" the
Radium-226/228 by inserting into a deathrow-er and then waiting for it to
stop emitting when the person expires. Perhaps the same argument would work
for all the nuclear fuel waste that Greenpeace keeps calling "intractable".
This is quite a boon for the industry, we owe him a beer at the very least.
