Electromagnetic fields
View through CrossRef
Basic characteristics of electromagnetic fields in the microwave, radiofrequency, and extremely low frequency ranges and their interactions with biological tissues are introduced, and parameters such as polarization and specific absorption rate used for safety assessment are highlighted. Techniques and instrumentation for measuring these parameters are discussed. The concepts of dosimetry are introduced and examples of electromagnetic field safety guidelines and standards are outlined. The chapter closes with a discussion of some topics directly relevant to safety of clinical procedures, such as hyperthermia, and diathermy, as well as electromagnetic interference with equipment and implanted devices caused by the presence of mobile communications and radiofrequency identification systems.
