When we consider the health effect of PM2.5, the size distribution of inhaled particle is the important factor as well as the concentration and the chemical component. The size distribution significantly alters the total and regional deposition in the respiratory tracts. However, regulations of PM2.5 are based on the mass concentration (μg m-3) without mentioning the particle size and components. In this report, Ipresent the importance of particle size using ICRP Publ.66 respiratory tract model for dose assessment of inhaled radioactive particles through the discussion on the relationship between particle size of PM2.5and regional deposition in the respiratory tracts.
