DENNY & ASSOCIATES, P.C. 49 <br /> CONSULTING ENGINEERS <br /> WASHINGTON, DC <br /> Engineering Statement Page 6 <br /> KNKA293,,Carrboro, North Carolina <br /> data logger memory for later analysis. The extremely low maximum exposure levels <br /> present at the site made rigorous analysis of the measurement data unnecessary. <br /> On the ground and inside the equipment shelter, the probe was scanned <br /> slowly in a vertical plane over an approximate one-square-meter area to simulate the <br /> surface of a human torso. At tight locations inside equipment racks containing cellular <br /> transmitters,filters, and combiners, and near transmission lines, there was not enough. <br /> space to make whole body measurements. These locations simply were probed to <br /> ascertain the electromagnetic field strength present. <br /> FINDINGS <br /> The exposure level present at each survey location was below the sensitivity <br /> threshold of the electromagnetic monitor. Measurements made inside the fenced area <br /> were repeated outside the fence with similar results. Thus, exposure at the site inside <br /> the tower fence and equipment shelter is less than 0.15 percent of the MPE for <br /> controlled environments, the sensitivity threshold of the instrument for controlled <br /> environments. At publicly accessible locations outside the fence,exposure was less the <br /> 0.75 percent of the MPE for uncontrolled environments, the sensitivity threshold of the <br /> instrument for uncontrolled environments. Because of the extremely low <br /> electromagnetic field strengths, it was not possible to distinguish cellular signals from <br /> ambient electromagnetic noise. Inside the equipment rack that housed the cellular <br /> transmittem exposure levels were found also to be below the sensitivity threshold of <br /> the electromagnetic monitor. <br />
