Remember that ELF fields vary by location. on the body resistance between the points of contact. This can burn both internal and external tissue and cause organ damage. Scientists realized that the power lines supplying all that energy to the worlds population were sending off EMFs, just like the sun does naturally. It can happen wherever there is live electricity. The FCC requires that all wireless communications devices sold in the United States meet minimum guidelines for safe human exposure to radiofrequency (RF) energy. If not, move the source away from you and the affected person using a non-conducting object made of cardboard, plastic or wood. This can cause minor discomfort to people, severe damage to electronic equipment, and fires and explosions if the air contains combustible gases or particles. The symptoms of an electric shock depend on how severe it is. Immediate treatment is, An allergic reaction can result in anaphylactic shock, which can be frightening and dangerous. Many say there hasnt been enough research into understanding whether EMFs are safe. If the loop is broken anywhere, the electricity can't get through. We need a balance . Grellier J, et al.
