Notes:

(1)  Statistical process 1 (Accumulation) does not change units. It is recommended to use another parameter without the word "time-integrated" in its name and accumulation in PDT.

(2)  Conversion factor between "Specific Activity Concentration" (14) and "Air Concentration" (10) is "Mass Density" [kg m-3].

(3)  Use the radionuclide release start date as baseline to determine activity arrival or activity end.
