The technique of estimating the intensity of the total impact of several simultaneously operating sources of electromagnetic radiation is proposed. The characteristics of antenna systems and peculiarities of radio wave propagation in rugged terrain are taken into account. A program for calculating the field strength has been developed, which allows visualizing the areas unfavorable from the point of view of the impact on the health of the population, for optimal planning of the location of radiation sources. At the first stage of research the most powerful sources of radio radiation - television and radio broadcasting stations - were taken into account.
