Electromagnetic fields (EMFs) arise whenever electrical energy is used. EMFs arise in our homes from all sorts of electrical appliances and in workplaces from electricity generation and transmission, broadcasting, radio and telephone base stations, dielectric and induction heating, welding, electric furnaces and medical equipment.
Exposure of people to high levels of EMFs can give rise to acute (short term) effects. The effects that occur depend on the frequency of the radiation. At low frequencies the effects will be on the central nervous system of the body whilst at high frequencies, heating effects can occur leading to a rise in body temperature. In reality, these effects are extremely rare and will not occur in most work situations
