Thank you for the responses this far. I should point out that it is not 
important to have the numbers right with a four digit accuracy. +/- 10 % is 
fine. I was asked this question by a person who in turn communicates with 
decision makers (including politicians) - we ran into a discussion about 
what is essentially an occupational health hazard (requires gamma shielding) 
and what is a potential risk in terms of 
distribution->uptake->ingestion->dose. I argue that there is still gamma 
there to consider after a few thousand years but I would like to have some 
numbers of course.

I normally stick to doses so this way of looking at the issue (activity 
only, alpha, beta and gamma separated) is unusual to me,
