I am only aware of the Berthold instrument which is a flow through 
proportional counter. I have not used one the major problem is they 
can only really be used for flat surfaces. But I have not used one.

Just the old fashioned way ie wipe testing followed by scintillation 
counting. (Oh and water dishes for tritium vapour)

Again unfortunately not, though you could certainly do charcoal or 
silica tube monitoring if you are looking for airborne OBT.
