We have a step in procedure to be aware of the potential for pure beta emitters when surveying radiogas system components. That's the only thing I can think of that we have in our process that would be specifically applicable to this issue. I'm not aware of us releasing a gauges from our waste gas system for calibration.

NRC Information Notice 96-51 reported instances where Kr-85 was fixed to internal surfaces of components from radioactive gas handling systems. Millstone would like to know how your plant is applying this notice to air flow gauges requiring periodic calibration outside the RCA? Thanks!
