摘要

The activity size distribution of the short-lived (~(118)Po, ~(214)Po) and long-lived (~(210)Pb, ~(210)Po) radon and the thoron (~(212)Pb, ~(212)Po) decay products and ~7Be in indoor air over a longer time period were measured. The radionuclides with longer half-lives show significantly greater activity median aerodynamic diameters (AMAD) than the short-lived nuclides. This increase in size of the original generated radioactive aerosol during its residence time in the atmosphere could be explained by coagulation with the non radioactive aerosol particles.
