Theoretical calculations of the propagation of waves in the range of medium, short and ultrashort frequencies in modulation of amplitude, frequency and pulse were made aimed at assesing the popula-tion's exposure to the electromagnetic field as a result of civil broadcastings in Havana City. Estimations of the sanitary protection zones and construction limits were obteined from European standards for installed transmiters operating at their maximum capacity. By using the patterns recognition technique it was observed that the sanitary risk was greater in the television transmitters from the western part of the city, in the broadcastings of modulated frequency from the center, and in one of the radar frequencies from the eastern part of the city. Multiple civil buildings were found in the alleged restriction areas. The risk was minimun in the medium wave broadcastings. The values resulting from the real situation, as well measured values show that the permissible level for human health is never transgressed. The theoretical calculation of the fields associated to the high voltage lines located at the pearly zones and in the city delimits an extension of the sanitary protection zone of hundreds of meters.
