Due
to the insufficient experimental data on static magnetic field exposure and
new ICNIRP limitations an exposure measurement instrument was developed. With
the new probe actual B0 and time varying magnetic fields due to
movement in the stray field can be detected simultaneously. Therefore,
personal exposure of 10 healthcare workers and MR physicists during normal
operating procedures could be determined. Peak exposure limits are exceeded
during all procedures.
