Laboratory Ventilation Standards

[Timothy.L.Popp@am.pnu.com]

  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.
