Hazards of radio frequency magnetic field and their prevention and control

The paper briefs the sources of radio frequency (RF) electromagnetic field, their hazards to human health and the hygienic standards of RF electro magnetic field for occupational exposure and for general population exposure. Based on the physical properties of RF electromagnetic field, the author put forward the comprehensive measures for controlling the electromagnetic radiation to meet the hygienic standards. These measures are improvement of the technology to lower the intensity of RF electromagnetic radiation, shielding the RF radiation sources to reduce the radio frequency levels in accessible areas, increasing the distance between the sources and human, and using personal RF protecting devices in area of high radio frequency levels, etc.. In protecting the general population from exposing to RF radiation, measures keeping a safe distance between the sources and the public play very important role, in which good city planning and the effective control of new and existing RF sources are very important. Referring to the RF electromagnetic problems by using electrical devices in the household, different measures based on the above principles for controlling RF hazards are also cited.
