摘要

This annual report summarizes investigations concerning various aspects of aerosols: modified double filter method for the measurement of radon or thoron in air; modified double filter apparatus for measuring radon and thoron in the environment and in exhaled breath; electrostatic charge on decay products of thoron; preparation of mondoisperse tagged polystyrene aerosol using an aerosol centrifuge; the performance of aerosol centrifuges at unmatched and matched relative humidities between stream air and aerosol air; diffusion coefficients of decay products of radon and thoron; measurement of specific alpha radioactivity with respect to size for uranium ore dust using aerosol centrifuge; a study of the attachment of thoron decay products to aerosols using an aerosol centrifuge.
