Neurological and physiological changes were measured in 55 male and 66 female workers, 18 to 49 years old, employed in the electronics industry in China. They had been exposed to radiofrequency (RF) radiation 6 hours/day, 6 days/week for 1 year. The subjects were asked about any central nervous system symptoms, cardiovascular symptoms, or sleeping problems. The authors conclude that exposure to RF radiation in industry can affect the cardiovascular system, particularly electrocardiogram parameters. A threshold limit for this type of RF radiation of 100 volts/meter was proposed.
