How close can you live next to power lines?
The recommended distance from high voltage lines is 200 meters. Houses that are 200 meters or more from a high voltage power line usually have typical radiation levels that have insignificant effects on human beings. You can live within the 50 meters limit for low voltage lines and still be safe from harmful radiation.
