Electromagnetic radiation is the form of radiation given off by electrical devices. It is increasingly regarded as a form of pollution and has been linked with possible health hazards, but the evidence for such links continues to be a matter of scientific controversy.

Environmental sources of electromagnetic radiation include power lines and pylon, as well as domestic items such as microwave ovens, televisions, computers, satellite dishes, mobile phones and electric blankets. Children are thought to be particularly vulnerable to the effects of electromagnetic radiation, and there are reports of increased incidence of leukemia among children living near power pylons and high voltage lines. Other disorder suspected of possible association with electromagnetic radiation include Alzheimer’s disease, birth defects, cancers, headaches, lethargy, memory loss, muscle pains and sleep disturbances, as well as such events as miscarriage, sudden infant death syndrome and suicide.
