Gj. Price et al., MEASUREMENT OF RADICAL PRODUCTION AS A RESULT OF CAVITATION IN MEDICAL ULTRASOUND FIELDS, Ultrasonics sonochemistry, 4(2), 1997, pp. 165-171
This paper describes the use of the terephthalate dosimeter to measure
the threshold and extent of cavitation arising from medical ultrasoun
d sources at high frequencies. Significant hydroxyl radical production
was noted from a physiotherapy source and low level activity was also
detected when using a pulsed, diagnostic type transducer system. The
effect of sound intensity and the type of field is described. The poss
ibility of using polymer degradation to monitor the cavitation is also
discussed. (C) 1997 Elsevier Science B.V.
