The object of this work was the design, construction,: and
evaluation of an aerosol generator capable of generating a stable,
homogeneous, radioactive aerosol in the submicron-particle-size range.
This report describes the generator which F. A. Hedman (ORNL 1352)
developed by modifying the La Mer aerosol generator.
The author has
constructed and tested a generator thus modified.
Performance tests showed
that the aerosol produced by the generator was stable over long periods of
time and that the machine will operate on less than 500 mg of generating
compound.
The aerosol produced is relatively homogeneous as evidenced by
the color bands visible in the aerosol when illuminated by a collimated
beam of white light.
