We have extensive experience in monitoring for tritium in all types of 
systems. We currently maintain inventory levels of approximately 100k Curies 
of tritium on site.  We use real time and passive types of monitoring 
systems for detection of tritium in our systems.  The passive monitoring 
types include bubblers and "DATS".  Both of these systems are discriminating 
allowing for the detection of oxide as well as elemental tritium.  We have 
built, calibrated, and tested bubblers using both water and other transfer 
materials.  Our HP field operations group uses bubblers on a daily basis.  
If you are interested in our experiences give me a call.  It would take 
volumes to e-mail specific information.
