Sex differences in the regional deposition of inhaled particles in the 2.5–7.5 μm size range
As part of a study to validate a chest phantom for the assessment of plutonium in lung, male volunteers inhaled 5 #m polystyrene particles labelled with 92mNb (half-life 10.2 days, 15.7-18 and 934… Expand
Regional deposition and clearance of particles in the human nose
Abstract The sites of particle deposition and clearance rates in the human nose have been investigated for inhaled monodisperse particles in the size range 2–10 μm. At least 45 per cent of the… 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 sized glass fibres in the respiratory tract of the rat.
The regional lung deposition of throron progeny attached to the particulate phase of environmental tobacco smoke
A γ emitting isotope of lead (( 212 Pb), a decay product of thoron ( 220 Rn)), has been used to radiolabel the particulate phase of aged and diluted sidestream tobacco smoke in situ. 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 excretion in breath of some aliphatic halogenated hydrocarbons following administration by inhalation.
Environmental Tobacco Smoke Retention in Humans from Measurements of Exhaled Smoke Composition
AbstractTwelve male volunteers were exposed for 60-min periods to 2 concentrations of aged and diluted sidestream tobacco smoke (150 and 920 μg m-3 paniculate), generated from a cigarette type… Expand
