Minimizing Exposure to Non-Ionizing Radiation in the Workplace
Non-Ionizing Radiation in the Workplace
Non-ionizing radiation in the workplace, if not properly controlled, can pose a health risk to exposed workers. Health effects by electric and magnetic field exposure source are noted in radar traffic devices, wireless communications with cellular phones, radio transmission, and magnetic resonance imaging (MRI). Studies note possible carcinogenic, reproductive, and neurological effects to worker health, so exposure should be minimized.
This type of radiation can come in forms of energy waves composed of oscillating electric magnetic fields traveling at the speed of light. Non-ionizing radiation doesn’t penetrate deep into our tissue cells but increases the risk of damage to skin and eyes. Dependent on the energy and exposure time, this type of radiation can cause localized heating, and photochemical reactions can occur with possible permanent harm.
Types of Non-Ionizing Radiation
Non-ionizing radiation includes the spectrum of ultraviolet (UV), microwave (MW) extremely low frequency (ELF), infrared (IR), visible light, and radio frequency (RF). Lasers commonly operate in the visible, UV and IR frequencies.
- Radiofrequency and Microwave Radiation - Microwave radiation is absorbed near the skin, while radiofrequency radiation may be absorbed throughout the body. At high enough intensities, both will damage tissue through heating. Sources of RF and MW radiation include radio emitters and cell phones.
- Visible Light Radiation - The different visible frequencies of the electromagnetic spectrum are "seen" by our eyes as different colors. Excessive visible radiation can damage the eyes and skin.
- Extremely Low Frequency Radiation - Extremely Low Frequency 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.
- Laser Hazards - Lasers typically emit optical (UV, visible light, IR) radiations and are primarily an eye and skin hazard. Common lasers include CO2 IR laser; helium - neon, neodymium YAG, and ruby visible lasers, and the Nitrogen UV laser.
- Ultraviolet Radiation - Ultraviolet radiation has a high photon energy range and is particularly hazardous because there are usually no immediate symptoms of excessive exposure. Sources of UV radiation include the sun, black lights, welding arcs, and UV lasers.
- Infrared Radiation - 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.
By using one of RAECO Rent’s area EMF or personal RF monitors, you can get accurate, traceable readings for both worker safety and health. Learn more about our EMF and RF exposure monitoring instruments.
