![]() ![]() This is as per building biology standards. Absolutely safe ELF value is shown in Green and is taken as zone where ELF is lower than 1mG.This is provided by Environment protection agency (EPA, USA). The threshold of human exposure value is taken at 2.5mG.ELF hazard values related to living near high voltage power lines.įirst we give the relevant definitions related to this model. Hazard zones have been marked in Red, risk zones have been shown in Orange and tolerance zones have been shown in Yellow. Consequently, we have also provided for the right of the way values for comparison. (This model is a simplistic one, and does not account for multiple other factors such as sag, transients etc). Hence, we plotted a safety zone taking optimum values of current through these conductor cables and field distance as coordinates. Therefore, a domestic supply cable produces lower ELF than a power distribution cable.Īs a second rule of the thumb, the further you move away from the conductor, the lower is the ELF radiation that you are exposed to. The distance of separation between the subject (person, family, premise) and the conductor.Īs a rule of the thumb, the higher the current through the conductor wire the higher is the ELF radiation that it produces.The current passing through the conductor.What is the safe distance of living near high voltage power lines?ĮLF exposure due to proximity to a high voltage power line depends upon 2 things. I am living near high voltage power lines. ![]() ![]() These risks extend much beyond the Right of way. Right of way for power distribution systems do not take into account ELF radiation risks from the conductors. Therefore, the right of way does not account for concentration of ELF radiation in the area around the current carrying conductors. This is to accommodate any accident that can cause a current carrying power cable falling on ground and risks of electrocuting, thereof. Power distribution laws dictate that this land is left alone. In most cases, it is the land 20-23 metres on both sides of the HT power transmission line. Right of way is an allowance of land around the power lines where no human habitation should be allowed. Most of the safety legislation around power lines are included in patch of land on both sides of the HT power line. But, there is legislation for safety from these power lines. Hence, it is not safe to live near power lines. Therefore, even while there is no scientific evidence, ELF radiation is a health hazard. This leads to hypertension, irritability, listlessness, decline in energy levels, obesity etc. It is known to cause headache, dizziness, fatigue and insomnia. Is it safe to live near power lines?ĮLF radiation from power lines is harmful to the body. If you wish to read more about ELF radiation, click here. Thereafter, it was validated by WHO in 2007. Extremely low frequency (ELF) radiation, is associated with increase in childhood leukemia by 200%. ![]() This is first researched by IARC in 2002. Passage of electrical current through a conductor causes ELF radiation. Extremely low frequency (ELF) radiation can cause cancer. Is there a significant risk? How far should you be staying from a high voltage power transmission lines?ĭo you stay near a high voltage transmission line? Or a transformer? Or an electric train line? Are there are domestic power lines very close to your house? If the answer to any of these questions is yes, then you should spend the next 5 minutes reading through this article. Should you worry if you are living near high voltage power lines. ![]()
