Characteristics, Dosimetry & Measurement of Emf

This paper describes characteristics of electromagnetic fields and their interaction with body as a fundamentals of electromagnetic field (EMF) safety issue. It also presents how engineering and physics contribute to this. EMF should be appropriately and precisely characterized when we consider its interaction with body. Dosimetry, which is the quantification of substance interacting with the exposed body, is of quite importance in the exposure assessment for both compliance testing with guidelines and the quality control of researches on EMF effects. The basic concept of these issues is summarized, and some researches mainly performed by the authors’ group are presented as exa mples of researches in this field.
