I'm not that concerned about very low level Alpha-emitters provided
they're not emitting anything else (Beta in particular). Alpha particles
don't get much farther than the very outer surface of the skin which is
already dead anyway.
You need to revise your radioactive hazard assessment John. Once
ingested it is the short penetration length of alpha which makes then so
dangerous. You don't have dead skin cells lining your lungs, for
example.
Your assessment is perfectly valid for alpha emitters when kept out of
the body, as I have already mentioned. Once inside the body they are
much more dangerous than beta because virtually every single alpha
particle is almost guaranteed to be absorbed by living tissue close to
the site of its emission, whilst a fair percentage of beta radiation
will pass right out of the body without causing any damage.
