Human chest clearance of Teflon particles with an aerodynamic diameter of 4.7 micrometers tagged with 198Au or 111In was studied with two apparatuses and two gamma-ray spectrometers for the external detection of the activity deposited in the respiratory tract. Approximately the same chest retention...
