nec209 Posted March 3, 2009 Share Posted March 3, 2009 Why do people call electronic devices or electrical devices radio frequency or part of the spectrum when it is not Radio,Microwave,Infrared,Visible, Ultraviolet,X-rays ,Gamma rays. I know every electronic devices when turn on or electrical devices when turn on have Electromagnetic field or any electric current have a Electromagnetic field . I know if the electromagnetic field is strong it can cause interference.That is why some times radios get interference from power lines ,cell towers ,electric saw if the electromagnetic field is strong.Any electronic devices or electrical devices cause interference if the electromagnetic field is strong. But can EMF do harm to the body or get cancer ?Are EMF bad for people.What is SAR ?? Link to comment Share on other sites More sharing options...
