Interaction of ELF Magnetic Fields with Human Body Organs Model Underneath EHV Transmission Lines

The current densities and the specific absorption rate are important factors to evaluate the biological effects associated with exposure to ELF magnetic fields. These important factors depend on the characteristics of the external magnetic fields and the human organs. In this paper a standard human model is considered. The important human organs are taken into consideration, wherever the maximum, minimum and average magnetic fields are calculated in these organs under central line conductor, under outermost conductor and at the edge of right-of-way. The maximum and average current densities at the above three situations underneath the line are calculated and discussed. Also, the specific absorption rates are computed and discussed. The magnetic field can be as high as 49.87 muT, the induced current density 615 muA/m², the specific absorption rate 29times10^-12 watt/kg in the human model brain. While in the human model heart the magnetic field can be as high as 47.44 muT, the induced current density 403 muA/m², the specific absorption rate 29times10^-12 watt/kg in the human model heart
