The AA. report the results of an inquest on the health effects of radio wave pollution in an area of Trieste, where television transmitters and broadcasting are installed. The following results were obtained: the measure of electromagnetic fields showed in the mentioned area a power density 10-100 times higher than that + in other zones of Trieste. According to present knowledge, the observed values of EM fields may have some psychological, behavioural and neurovegetative effects on exposed subjects. Clinical examination, integrated by the analysis of some seventy biochemical and functional parameters, showed nothing but minor changes of hypophyseal-suprarenal hormones and a relevant incidence of neurovegetative troubles. Some difficulties were found in the interpretation of psychological troubles, which may be reactive to broadcasting installation or secondary to radio wave exposure.
