| Abstract |
The statement concerned National Institute for Occupational Safety and Health (NIOSH) research programs relating to occupational exposure to radiation. Much epidemiological data points to exposure to radon daughters as hazards to uranium miners and milling operators. Problems also arise from the operation of radiation generating equipment. Nonionizing radiation hazards included visible, ultraviolet, radiofrequency and microwave radiation, infrared and ultrasonic radiation. Ultraviolet radiation can cause sunburn, eye damage, depigmentation, precancerous tumors, basal and squamous cell cancers, and malignant melanomas. Infrared radiation has been implicated in the development of cataracts. Laser radiation was linked with burns and fire hazards. The only hazard associated with visible radiation thus far has been eyestrain due to the lack of sufficient light while performing a given task. Optical radiation exposures occurred among workers using cathode ray tubes, such as computer screens, in their jobs. Workers were exposed to many sources of microwave and radiofrequency radiation from radio and radar transmitters, industrial drying equipment, heat sealing and curing equipment, and certain medical research devices. Training and support services were mentioned. |
