Computational Techniques of Electromagnetic Dosimetry for Humans

Assessment methods for electric and magnetic fields in low and intermediate frequencies related to human exposures and the status of their standardization

“…Calculations related to conversion between external electromagnetic fields and induced electricity are called dosimetry, being an important technique to derive reference levels or to evaluate compliance with basic restrictions set in the guidelines. With the recent progress in numerical techniques 18,19 and development of sophisticated numerical human body models 22,23 based on magnetic resonance imaging (MRI) and other methods, the latest findings of dosimetry have found practical application; thus, the revised edition of ICNIRP guidelines of 2010 10 refers to calculated results of induced electric field using a detailed model of human body with a resolution of 2 mm. Below computational evaluation methods and the latest trends are considered mainly with respect to exposure to magnetic fields.…”

“…In addition, basic restrictions are derived assuming exposure to a uniform magnetic field under which coupling with the human body is the strongest, to be on the safe side. Calculations to determine relationship between external electric/magnetic fields and induced effects in the body are referred to as dosimetry, being a long studied topic in the field 18,19 . This will be explained in the next section.…”

“…Calculations to determine relationship between external electric/magnetic fields and induced effects in the body are referred to as dosimetry, being a long studied topic in the field. 18,19 This will be explained in the next section. In addition to direct human exposure to electromagnetic fields (direct effects), ICNIRP guidelines provide regulations (reference levels) to restrict contact currents (indirect effects) that pass the human body under electromagnetic field through contact to objects that differ in electric potential from the human body (Table 3).…”
