Electromagnetic radiation emitted from video computer terminals.

There has been a developing concern about potential health hazards attributable to electromagnetic radiation from video computer terminals. Since users of these devices typically spend many hours daily in close proximity, they would be subject to chronic long-term exposures to any emitted radiation. Radiation was detected at frequencies ranging from 1.5 kHz to 1,420 MHz in the RF portion of the EM spectrum and from 350 nm to 600 nm in the ultraviolet and visible region. However, the levels were far less than the most restrictive permissible exposure levels established by any agency or government of any nation. There is no experimental or epidemiological evidence presently available to indicate that these levels of RF radiation have any deleterious effects on the human biological system.
