[ RadSafe ] Limits on airflow from a contamination-control area

[WHILLANS David -NUCLEAR]

Radsafers,

Our company is interested in industry standards for the control of
airflow out of a contamination-control area, especially in a reactor
environment, and how this is monitored. Specifically,

*	What air flow rate out of a contamination-control area is
considered acceptable in the rest of the industry? (possibilities, "air
must always flow into the rubber area",  1 m/s, 1 km/h, etc.)
*	What techniques are used to determine that air flow does not
exceed the acceptable rate?  (possibilities: smoke bulb tests, pocket
anemometer, "if you can feel it on your face it is too much",  etc.)
