Bi-212 - Thanks!

["Andrew Karam" <akaram@safety.rochester.edu>]

Many thanks to all who responded regarding the Bi-212 generator I asked
about yesterday.  It looks as though production of these generators is
being moved from ANL to ORNL.  It was pointed out to me that Bi-213
generators exist that do no have the high-energy gamma associated with
them.  These would be easier to shield than the Bi-212 generators.  In
addition, one person noted that the Bi-212 generators also generate a fair
amount of Rn-220.  I will recommend to our researcher that he look
seriously at the Bi-213 generators since they are currently available and
seem to be easier to handle radiologically.

Thanks again to everyone who took the time to respond to my question.
