Modeling of Radon and Daughter Concentrations in Ventilated Spaces
In order to predict indoor radiation levels due to radon daughters at low building ventilation and air leakage rates, differential equations governing the decay and venting of radon Rn-222 and its daughters were solved. A computer program based on the solutions was written to predict radon and daughter concentrations, total potential alpha energy and equilibrium factor. The program can account for time dependence of ventilation and emanation rates and is readily usable by building designers. Sample calculations using the program showed that tightened buildings can commonly have potential alpha energy levels near 0.01 working level (WL), a level more than twice as high as concentrations currently found in most houses.
