摘要

The dose conversion factor (DCF) which gives the relationship between effective dose and potential alpha energy concentration of inhaled short-lived radon decay products is calculated with a dosimetric approach. The calculations are based on a lung dose model with a structure that is related to the new recommended ICRP respiratory tract model (ICRP 66).rnThe characteristics of the radon decay products concerning the unattached fraction and the activity size distribution of the radon decay products are important input quantities for the calculation of DCF. The experimental data about these quantities obtained from measurements in homes, at work places, and in the free atmosphere near ground in the last past years are reported.rnThe DCF fraction of the unattached (DCF_u) and aerosol-attached (DCF_(ae)) radon decay products for different places are presented, taking into account the measured characteristics. The influence of the unattached radon daughters on the dose conversion factor DCF_u is reported and compared with the DCF_(ae) of the aerosol fraction.
