given the chemical forms indicated, i anticipate much of the radiation 
will go up the stack.  reactions w/ these compounds that i am familiar 
w/ tend to be accompanied by gaseous releases.  any surface 
contamination should be easy to decon.

for H-3 you have to use LSC, for the C-14; unless unusually "large" 
quantities (many millicuries) are in use LSC surveys should be 
sufficient. 
 
if you're in the market for handheld detectors (GMs w/ thin window 
probes) because you wish to directly monitor for C-14 you could contact 
any of the instrument vendors, they'll be glad to send a catalog.  try 
WB Johnson, Eberline, Bicron, and Victoreen for starters.
