RADON - MEASUREMENTS RELATED TO DOSE

In the first part of the paper, the parameters of the airborne radon d aughters for dose estimation are defined. In the second part, the most important methods and techniques for measurement of the potential alp ha energy concentration, the unattached fraction (cluster-fraction), a nd the activity size distribution of the radon decay products are repo rted. At the end, the dose conversion factor for different exposure si tuations obtained from model calculations are presented. These values vary between 6 mSv/WLM and 39 mSV/WLM depending on aerosol condition a nd Physiological parameters of inhalation (inhalation rate, nose/mouth breathing) at different places (home, open air, working places). Thes e factors are based on the new human respiratory tract model of ICRP 6 6,taking into account the different radon daughter characteristics. Co pyright (C) 1996 Elsevier Science Ltd.
