International organizations have collaborated to revise standards and guidelines for human protection from exposure electromagnetic fields. In the frequency range of 6–300 GHz, permissible spatially averaged epithelial/absorbed power density, which is primarily derived thermal modeling, considered as basic restriction. However, averaging methods density inside tissues, only a few groups presented calculated results obtained using different conditions numerical methods. Because experimental...
An in situ (internal) electric field is used as a dosimetric quantity for human protection from low-frequency electromagnetic fields (lower than 5 MHz) under international safety standard/;guidelines. The IEEE standard uses homogenous elliptical cross section to derive external strength corresponding an strength, while the International Committee on Non-Ionizing Radiation Protection (ICNIRP) guidelines use anatomical models relate them. In latter, "the 99th percentile value of averaged over...
International guidelines and standards for human protection from electromagnetic fields have been revised recently.

Recently, international exposure guidelines/standards for human protection from electromagnetic fields were revised. For frequencies between 6-300 GHz, the permissible incident power density is defined as reference level, which derived a new metric “absorbed/epithelial density” based on thermal modeling. However, only few groups computed and resultant temperature rise at greater than 6 where their conditions different. This study presents first intercomparison of in body exposed to different...
