John, you might also be able to get away with the old standby "6CEN" if you don't have a book or internet handy.
6 x the Curie Content x the photon energy in MEV x the abundance = R/hr @ 1 foot. Divide by distance squared corrects the estimate for distance.

Thank you all,
This is one of the many reasons I signed up for RadSafe. Quick help when my brain shuts down and interesting debate on topics of radiation safety.
Still glad to be a part of this list,
