Non-ionizing Radiation Information
Non-ionizing radiation is described as a series of energy waves composed of oscillating electric and magnetic fields traveling at the speed of light. Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and tremendously low frequency (ELF). Lasers commonly operate in the UV, visible, and IR frequencies. Non-ionizing radiation is found in a wide range of work-related settings and can pose a considerable health risk to potentially exposed workers if not properly controlled. This page provides links to technical and regulatory information on the control of work-related dangers from non-ionizing radiation.
tremendously Low Frequency Radiation (ELF)
ELF radiation at 60 HZ is produced by power lines, electrical wiring, and electrical equipment. Common sources of intense exposure include ELF induction furnaces and high-voltage power lines. |
Radio Frequency (RF)/Microwave Radiation (MW)
Microwave radiation is absorbed near the skin, while RF radiation may be absorbed through out the body. At high enough intensities both will damage tissue through heating. Sources of RF and MW radiation include radio emitters and cell phones. |
Infrared Radiation (IR)
The skin and eyes absorb infrared radiation as heat. Workers normally notice excessive exposure through heat sensation and pain. Sources of IR radiation include furnaces, heat lamps, and IR lasers. |
Visible Light Radiation
The different visible frequencies of the electromagnetic (EM) spectrum are "seen" by our eyes as different colors. Good lighting is conducive to increased production, and can help prevent incidents related to poor lighting conditions. Excessive visible radiation can damage the eyes and skin. |
Ultraviolet Radiation (UV)
Ultraviolet radiation has a high photon energy range and is mainly dangerous because there are usually no immediate symptoms of excessive exposure. Sources of UV radiation include the sun, black lights, welding arcs, and UV lasers. |
Laser dangers
Lasers typically emit optical (UV, visible, IR) radiations and are primarily an eye and skin danger. Common lasers include CO2 IR laser; helium - neon, neodymium YAG, and ruby visible lasers, and the Nitrogen UV laser. |
