摘要

Considerations of physical aspects are crucially important when we investigate biological effects of electromagnetic fields (EMF). Observation of difference in the responses of biological specimen with and without exposure is not sufficient to provide the basis for health risk assessment. Careful consideration of physical aspects must follow the observation to confirm the biological significance of the observation. Physical aspects are important in the description of the initial event of interaction. Electric and magnetic fields exert forces on charges. The forces on charges should be the initial interaction of electric and magnetic fields with matter including biological body. In some cases the force might directly affect some biological process. In other cases, however, it just causes changes in physical environment of the specimen, which affects biological function indirectly. Another physical aspect of importance is "electromagnetic dosimetry". Charges and polarized molecules in matter are forced to move when the material is exposed to electric and/or magnetic fields. Thus the electric and magnetic fields in tissue in situ are different from the incident fields. Electromagnetic dosimetry is the analysis and experiments to identify the resultant electric and magnetic fields in situ. The development of dosimetry has contributed to improved accuracy of exposure condition and reproducibility in biological experiments. In this paper we discuss these physical aspects of EMF which are needed for biological studies.
