Salutations from the frozen tundra (at least for today) of the
southern U.S.

Warning wrt the following message:

>The Rad Health Handbook (Revised Ed., 1992) has it as 2.440E-5 
>(mSv/h)/MBq (mu in cm-1).

A gamma constant has to include a distance squared term. For the
above value it is meters squared.  i.e. the constant is in 
mSv/hr at 1 meter from a megabecquerel source

The table from which the number comes also includes mu in cm-1 but
that is unrelated to the gamma constant units. The table was a
summary of data in  an Unger and Trubey ORNL document  RSIC-45/R1.
