Abstract

There has been much discussion about possible health risks from exposure to power system electric and magnetic fields. The induced current densities in a human body located in these extremely low frequency fields can be determined by calculation. The basic restriction of the ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for 50 Hz fields is 10 mA/nf (to workers). The aim of this study is to examine the induced current densities due to power system fields in the working environment by using the spheroidal calculation model. The study includes 27 workers exposed to electric and magnetic fields from power systems in different work environments. The fields in the wo
