Ray,
I have
been moved within the BNL so often and so many times, so I
have lost most of my beta-dose calculation references.
If I recalled correcly, in the one of the early issue
of "Radioactive & Radiochemistry" Jouranl has
your Co-60 infomation. The article is described a MIT study
on Co-60 spheres as "Hot
particle". I hope somebody can share this Journal
with you, otherwise you can contact the Publisher at: (404) 352-4620
or caretakercom@mindspring.com
Good
luck to you,
casper
