Exposures to radiofrequency microwave (RF/MW) radiation were investigated on September 21, 1981 at AT and T Long Lines (SIC-4811) in Atlanta, Georgia. The evaluation was requested by the employees on behalf of an unspecified number of workers using the microwave telephone relay facility. Radiation was measured around the transmitting equipment and on the roof at the base of the transmitting antenna. The highest RF/MW radiation measurement was 600 square volts per square meter (V2/m2) on the floor immediate at the transmitter; the OSHA standard is 40,000V2/m2. No radiation was detected at 5 to 10 centimeters from the source. Radiation leakage was stopped when the waveguide flange screws of the radiofrequency shields were tightened. No radiation was measured on the roof. The authors conclude that no RF/MW radiation exposure hazard exists.
