How do radio frequency radiation and electromagnetic fields affect human beings? All living organisms are sensitive to radio frequency radiation (RFR) and electromagnetic fields (EMFs). Life depends on this sensitivity at the correct intensity. For example, radiation from the sun helps humans make vitamin D, but too much causes cancer. Scientific evidence shows that some people can sense changes in atmospheric electricity like thunderstorms, while 3.6% are sensitive to man-made RFR/EMFs. To prot
