An FM broadcast tower was surveyed to determine the radiofrequency exposure levels to which personnel working on such towers would be exposed during such tasks as painting, beacon replacement, repairs to de-icing equipment, antenna adjustment, and tower rigging and replacement. High intensity radiofrequency fields in excess of 180 mW/sq cm were found on the tower. To prevent a worker's exposure from exceeding OSHA standards, he would be allowed to work in this field only 20 seconds in each 6 minute period. Since this is impractical, it was suggested that tower work be performed only when the transmitter is turned off.
