AIR MONITORING Concentration Concentration is activity per volume of air and may be stated as dpm / cubic meter, ìCi / ml, or Bq / cubic meter. DAC (Derived Air Concentration) is another way to express airborne radioactivity concentrations as relative hazards.

AIR FLOW METER CORRECTIONS Mass Flow Meters Q S = Q A (P A /P S x T S /T A ) Q A = Q S (P S /P A x T A /T S ) where; Q S is the STP flow rate Q A is the ambient flow rate P S is STP pressure P A is the ambient pressure T S is STP temperature T A is the ambient temperature Rotameter Corrections Q S = Q I x P S /P A x T S /T A √(P S /P I x T A /T S ) where; Q I is the rotameter flow indication P I is the actual pressure inside the rotameter. This correction assumes the rotameter markings are correct at STP. The actual pressure inside the rotameter should be used in the calculations. For personnel protection against particulate airborne radioactivity ambient sample volumes instead of volumes corrected to STP should be used for calculations. The ambient respiratory rate will remain the same as atmospheric pressure changes from STP up to an elevation of approximately 12,000 feet (3,660 Meters). 71 AIR FLOW METER CORRECTIONS Mass Flow Meters Q S = Q A (P A /P S x T S /T A ) Q A = Q S (P S /P A x T A /T S ) where; Q S is the STP flow rate Q A is the ambient flow rate P S is STP pressure P A is the ambient pressure T S is STP temperature T A is the ambient temperature Rotameter Corrections Q S = Q I x P S /P A x T S /T A √(P S /P I x T A /T S ) where; Q I is the rotameter flow indication P I is the actual pressure inside the rotameter.
