Instrument
used to measure the Fuchs surface area of aerosols directly: the aerosol
is passed through a charging chamber where lead isotopes created from a
decaying actinium source are attached to the particle surfaces; the particles
are transported through a capillary to a collecting filter; the amount of
radioactivity measured is proportional to the particle surface area
