But should we be worried? They create and support wound healing. European scientists also uncovered a possible link between EMF and leukemia in children. Dont move someone who has been shocked, unless theyre in danger of further shock. Possible symptoms related to EMFs in the studies included: EMF exposure levels are monitored and enforced at the global, national, and local levels in a varied patchwork of procedures by multiple organizations, depending on where you live. Also, the strength of the magnetic field may vary a lot even among similar products. Find out more with BBC Bitesize. Power lines are also considered safe, as long as you keep a safe distance from them. People can follow this advice: Electric shocks can cause injuries that are not always visible.
