Just in case Alison does not have any reference material about ultrasound
effects I do have a couple of references of interest.
Journal of Nurse-Midwifery Vol. 29, No. 4 July/August 1984
Fetal Effects of Ultrasound:  A Growing Controversy
By Doris Haire

FDA Consumer, March 1983, Department of Health and Human Services
The Unknowns of Ultrasound
By Richard C. Thompson

Federal Register, Vol. 44, No. 31, Tuesday, February 13, 1979
Docket No. 78N-0288  Diagnostic Ultrasound Equipment
Department of Health, Education and Welfare

Just for information sake I would like to add my .02 on ultrasound.  I
have recently spoken with a physics professor here at the Uni. of
Illinois about ultrasound.  I am not a sceintist and therefore do not
understand all the discussion about ultrasound but this is what he told
me.  He says that Ultrasound is radiation.  It is aucustic radiation.  It
is supposedly non-ionizing radiation.  Non-ionizing means that it does
not break molecular bonds.  However he told me that in the human body
most of the molecular bonds are with hydrogen which makes a very weak
bond and can be broken with ultrasound.  He stated that he has a colleage
in Germany who has been working with the effects of ultrasound on human
DNA.  As we all know DNA is shaped in a spiral.  WHen it is subjected to
ultrasound his colleage states that it will temporarily unspiral and
become like a strate ladder.  He also mentioned that ultrasound is used
in a procedure to remove kidney stones.  The ultrasound will break the
calcium carbonate bonds of the stones and the people being treated
sometimes can feelk it happening.  So much for the non-ionizing theory.
He stated to me that he would not subject any of his 6 children, his wife
nor himself to any type of ultrasound unless it would mean their lives.
"Too many physists have died with this exposure doing their research."
He also stated that it will be another 50 years before we really know
what the effects of ultrasound are.  Slight changes in DNA and molecular
structures take generations to show up.
O.K. I will get down off the soap box.
