We appreciate any feedback you may be able to provide on the following 
questions:

For high contamination work within an RCA do you monitor the exhaust of the 
portable HEPA units( 1000 or 2000 CFM) used to control radioactive 
contamination with a continuous air monitor (AMS-4/grab air sample)?  Is there 
a contamination criteria that prompts you to monitor the exhaust?
