Ion cyclotron resonance was presented in the early 1980s as the biological mechanism responsible for possible carcinogenic effects of 50 or 60 Hz radiation. Electromagnetic radiation of such a frequency is emitted by high-voltage power lines and by devices that take their energy from the power grid. After many years of research, a consensus developed that there are no health effects associated with doses that are normally encountered in daily life. Meanwhile the alternative medicine industry has for many years been making devices that deliberately produce electromagnetic radiation with frequencies in the vicinity of 50 or 60 Hz. Different scientific misconceptions circulate about how such radiation can lead to great health benefits. Ion cyclotron resonance is one of these theories.
