Abstract
Biological effects of electromagnetic fields on the human body, animals and plants have been a subject of scientific interest and public concern for their risk on the living organisms such as blood leukemia and others. The high voltage transmission and distribution lines, which pass beside some houses, factories and schools are source of electromagnetic fields. This paper presents the field calculations around and near of high voltage transmission lines 220 kV and 500kV. To calculate the induced current, the power density, the electric field and the magnetic field of grounded and ungrounded human body cylindrical model are used. MATLAB program package is used for mathematical calculation of the distribution of the EMF in human body under high voltage power transmission lines.
Highlights
Electric and magnetic fields produced by electric power systems have recently been added to the list of environmental agents that are a potential threat to public health [1, 2]

Summary
Electric and magnetic fields produced by electric power systems have recently been added to the list of environmental agents that are a potential threat to public health [1, 2]. Beneath high-voltage transmission lines, the electric fields created have the same frequencies as those carried by the power lines. The characteristics of these fields depend on the line voltage, and on the geometrical dimensions and positions of the conductors of the transmission line. In this paper calculations are carried out for the electromagnetic fields near the overhead transmission lines and the induced current produces in human body due to these fields. In this paper the electric field E, induced in the human body when exposed to a transmission power line electric field Einc, is determined in analytical form using the surface integral equation method.
