TITLE
ULTRASONICS FOR RADIOACTIVE DECONTAMINATION
ABSTRACT Tests have been run to determine in .a preliminary
fashion whether ultrasonic vibration would be effective in
removing mixed radioactive deposits from the inside surface
of steel pipes in a heat exchanger. Different frequencies
(20 KC/S:, 1000 KC/S) have been used at the maximum power
levels convenietnly attainable. Different liquids were
compared for cleaning effectiveness, with and without

CONCLUSIONS Mild stirring of water bath at room temperature
produced virtually no cleaning effect on the samples.
Ultrasonics in water, at room temperature, gave 50%,to 80%
cleaning (as defined by gamma ray count) in 15 minutes. or
less. Certain chemical solutions gave moderate cleaning
results without ultrasonics; but the effectiveness of these
solutions was greatly enhanced by the addition of ultra-
sonics. It was found, as expected, that the effectiveness
of the sound wave depended rather critically on the method
of coupling to the work.AUTHOR.
