Maybe I missed your humor but, the units are unimportant - transferable
activity per some unit area is the same regardless of the units you quantify
it in. (the rest of the world usually uses Bq/cm^2 or Bq/m^2) The basis in
question is the method, not the reporting units.  I think Paul's description
of practicability hits the mark.
