In response to a request from the Federal Occupational Health Office in Seattle, Washington, an investigation was begun into possible hazardous exposures to microwave and radiofrequency radiation at eight US Army Corps of Engineers field stations (SIC-4899) in Washington, Idaho, and Montana. At each station, radiation measurements were taken in the equipment building, at the base of the tower, and during a 6 to 9 minute tower climb. Analysis of the data indicated that Corps of Engineers maintenance workers were not exposed to microwave radiation in the 1.7 to 1.8 gigahertz region. However, exposures above the guidelines may occur from radiofrequency sources located either on the towers or on adjacent towers not part of the Corps of Engineers projects and operated primarily in the 100 to 300 megahertz region. In and around the equipment buildings, exposures to microwave and radiofrequency radiation sources appeared to be below guidelines. The authors conclude that workers who climb towers were exposed to electric and magnetic fields which may be in excess of occupational exposure limits. The authors recommend that workers who climb towers be trained on potential exposure and techniques to reduce these exposures.
