The resident ambient air land use equation, presented here, contains the following exposure routes without half-life decay:
inhalation
external exposure to ionizing radiation
total
In situations where the contaminant in the air is not being replenished (e.g., an accidental one-time air release from a factory), decay should be used. In situations where the contaminant in the air has a continual source (e.g., indoor radon from radium in the soil, or an operating factory or landfill cap), the equations without decay should be used. The decay function, found in section 4.10.7, can be multiplied by the ambient air equations above to acquire ambient air DCCs with decay. Farmer Air CDIs
