The conventional sampling methods of filtration and impaction are generally utilized in the collection of air samples at Hanford. In addition, a Goetz aerosol spectrometer is available for special studies. Particle-size determinations are made by autoradiographic studies making use of both optical and electron microscopes. A supplementary tool sometimes utilized is the Royco Particle Counter. The study included an analysis of the potential usefulness and the limitations of these air sample study methods for plutonium aerosol particle size measurement. Preliminary results, from a continuing study of the particle size distribution in normal and abnormal air, show particle sizes ranging from hundredths to tens of microns. The studies include considerations of the usefulness of particle size data in planning biological experirnents and in the application of these data to human internal deposition cases. (auth
