Abstract :This work presents the survey of magnetic field measurements taken around the high and medium voltage power lines, and induced current densities, at the outer edge along the body heights with different body types, calculated by using real data. Survey was carried out in city of Antalya, Turkey. There, more then 2,000 families, about 200 workers and a thousand of primary school students are in the focus of this study. Surveyed region in this study in ±75m band of power lines is reading a magnetic field between 1µT and 5.2 µT, bedrooms in the apartments are reading up to 0.7 µT, and class rooms are reading up to 0.35 µT in the surveyed region. Induced internal electric fields and current densities in the occupants’ body due to exposure to external magnetic fields produced by a conventional power lines such as 380,154 and 34.5 kV insert ignore into journalissuearticles values(50Hz); have been investigated. Induced current density for 5 years old child is calculated as about 10 insert ignore into journalissuearticles values(µA/m2);, and 15 insert ignore into journalissuearticles values(µA/m2); for average man
