Occupational Hazards from Non-Ionizing Radiation.

NIOSH 1977 Jul:41-45
Practical issues involving potential non ionizing radiation hazards occurring in the occupational setting were discussed, including hazards arising from arc welding, radio frequency heaters, incandescent filaments, gas discharge lamps, lasers, and electronic cardiac pacemakers. In arc welding the significant nonionizing radiation hazards result from those of the infrared, visible and ultraviolet spectrums with the classic hazard being ultraviolet keratoconjunctivitis, also known as flashed eyes. Overexposure to radio frequency (RF) power has occurred in glue heaters, plastic sealers and welders, and dryers. There are both direct biological consequences and indirect hazards such as influence on electronic cardiac pacemakers. One RF heater appearing in increasing numbers on the industrial scene is the microwave oven. When considering hazards from incandescent filaments, in addition to the hazard of whole body heating, the question of retinal hazard occasionally has arisen as well. Usually there is no hazard from a bulb with frosted glass or some other diffusing arrangement. The bare tungsten filament may be a retinal hazard. High temperature filament operation combined with an envelope transparent to ultraviolet rays such as quartz/halogen lamps emit potentially injurious amounts of ultraviolet rays and have caused burned and scratchy eyes. Gas discharge lamps have caused an ultraviolet hazard. No significant hazards have been attached to blacklights, low pressure mercury arc lamps. Lasers have been thoroughly regulated in attempts to control their obvious hazards. For persons with electronic cardiac pacemakers, counseling by the cardiologist or cardiac surgeon with respect to electromagnetic interference and potential sources of trouble on the job setting must be carried out.
