DB/DT System Hardware and Protocol for Investigating the Health Effects of Rapidly Changing Magnetic Fields

摘要

The increased use of rapidly changing magnetic fields in areas such as medical imaging has sparked interest in the possible health effects of exposure to such fields. Two know physiological effects are the induction of magnetophosphenes (visual flashes of light), and enhanced bone healing and growth. A dB/dt (rate of change of magnetic field with time) of as small as 5 T/sec can be sufficient to induce magnetophosphenes. Since growing cells show particular sensitivity to rapidly changing magnetic fields, it is likely that more serious health effects may be observed in mice exposed during embryogenesis. This paper details the hardware and protocol developed to investigate these possible health effects. 8 references. (ERA citation 09:015183)
