The study demonstrates, for the first time, the feasibility of monitoring occupational exposure of MR workers to ultra high static magnetic fields using a portable dosemeter. The 3 axis hall probe logging device provides valuable data on the magnitude and the duration of the B0 exposure and is capable of logging data for upto 8 hours. Routine activities carried out during a typical day can now be quantified and recorded to aid epidemiological investigations. Two MR workers carrying out typical daily tasks revealed integrated field exposure values of 128.7 and 135.5 Tesla seconds at 3 Tesla.
