Studies on the deposition of inhaled fibrous material in the respiratory tract of the rat and its subsequent clearance using radioactive tracer techniques. 1. UICC crocidolite asbestos.
Abstract Radioactive tracer methods were used to study the distribution of crocidolite between the upper and lower respiratory tracts after single short inhalation exposures of the “nose only” type.… Expand

Abstract Radioactive tracer techniques were used to measure the partition coefficients of four aliphatic fluorinated hydrocarbons in olive oil and serum. These compounds were shown to have a low… Expand
Deposition of Aerosol Particles in the Nasopharyngeal Region of the Human Respiratory Tract
THE interest of those concerned in any way with the provision of protection against inhalation hazards, especially those associated with work with radioactive materials, has been stimulated by the… Expand
Deposition of aerosol particles in the nasopharyngeal region of the human respiratory tract.
Abstract Experiments have been made to measure the deposition of radioactive monodisperse polystyrene particles of size between 1 and 10 μm dia. aspirated through the nose and mouth at known… Expand
Regional deposition of 2.5-7.5 μm diameter inhaled particles in healthy male non-smokers
Airborne monodisperse particles in the size range 2.5–7.5 μm dia., labelled with 99mTc, were systematically administered to mouth breathing subjects under different but predetermined breathing… Expand
The development of a system for the exposure of mice to aerosols of plutonium oxide
Abstract A system is described for the administration of plutonium oxide aerosols to mice in order to study the pathological effects in the lung. Included are details of(a) the technique for… Expand
Pulmonary deposition of inhaled particles with diameters in the range 2.5 to 7.5 micron.
Monodisperse polystyrene particles of 2.5,5 and 7.5 micron diameter, labelled with technetium-99m, were administered to mouth-breathing subjects respiring at a rate of 10 breaths min-1. Measurements… Expand
