Magnetic Field Exposure From Nearby Transmission Lines

Several studies have evaluated the possible associations between exposure to non-ionizing electromagnetic fields (EMFs) from power lines and cancer in children[1]. Power lines produce magnetic fields continuously, and the intensity of both electric and magnetic fields decreases with distance from the source[2][3][4]. Studies have had mixed findings regarding a possible association between living near electric power lines and childhood leukemia[1], but some have analyzed combined data from multiple studies of power line exposure and childhood leukemia[1]. Workers in the electric power industry can be exposed to high levels of EMFs on the job[3]. The International Agency for Research on Cancer (IARC) has classified extremely low frequency magnetic fields as “possibly carcinogenic to humans” (Group 2B)[3][4]. With most types of radiation, the electric and magnetic fields are coupled[4]. You can reduce your exposure by increasing your distance from power lines or electrical appliances, using shielding materials such as grounded shielding paint, faabrics or other materials.
