Abstract
Telegraph and radiofrequency (longwave, medium wave, shortwave) broadcasting stations have been in operation for over half a century. Some of these facilities are assigned to transmit worldwide and must be operated with high transmitted power (field strenghts), sometimes exceeding 1 MW. As the field strenght may be very high in the immediate surroundings of radiofrequency broadcasting stations, limits for the allowable exposure to radiofrequency fields were established early. For example, allowable exposure limits in Germany are set forth in DIN/VDE 0848 by the national standard committee “Deutsches Institut für Normung”, and in the United States in ANSI C95.1 provided by the American National Standards Institute. Concerning exposure limits, broadcasting companies must provide fences around transmitting facilities. Depending on power and frequency of transmission, fences may surround areas from 400 m2 to more than 100,000 m2.
