inhalation (The inhalation exposure route is only calculated for C-14 and H-3 as well as Rn-222, Rn-220, and Rn-219, including their short-lived progeny. Also, volatilization in the equation comes from household uses of water (e.g., showering, laundering, dish washing). To account for disequilibrium between radon and its progeny, an Activty Equlibrium Factor (Aeq) based on household air exchange rates is also applied. See section 4.10.8 of the users guide for additional information.)
