RE: Laboratory Ventilation Standards

[Antoine Philippe <pantoine@SCKCEN.BE>]

At the Belgian Nuclear Research Center SCK·CEN, the requirement is at least
5 air changes per hour. There is a pressure difference of at least 30 Pa
between the laboratories, where radioactive products are manipulated, and a
normal zone.

  I was wondering what other institutions with research type 
  laboratories using radioactive materials required for ventilation 
  purposes.  Currently, we require a minimum of 10 air changes per hour 
  in a laboratory using radioactive materials.  The majority of the 
  research is done with minimal amounts of H-3 or C-14, typically 1 to 2 
  mCi or less per experiment.  For energy conservation reasons, we are 
  considering reducing this requirement.
