|---|
Jacobi parametric room model was extended to the three modal distribution of aerosols, and applied to 220Rn progeny. The computer program was developed to calculate ratios of progeny activity concentrations in different modes to 220Rn concentration. The ratios are relatively small and they are given as functions on ventilation rate. Dose conversion factor (DCF) for 220Rn progeny was calculated as 4.5 mSv WLM1, which is smaller by over three times than that for 222Rn progeny.
