The physical conditions are <br /> that the following personal wireless services antennas would be mounted on the monopole:Verizon <br /> Wireless and AT&T Wireless. The measured values of power density are presented as a percent of <br /> current Maximum Permissible Exposures [%MPE] as adopted by the Federal Communications <br /> Commission [FCC] Z-', and those established by the Massachusetts Department of Public Health <br /> [MDPH] ° (With 100% signifying an acceptable amount). <br /> SUMMARY <br /> Broadband measurements of existing ambient RF fields in the general vicinity of the <br /> proposed site indicate the peak(maximum) field to be about 0.15%of the regulatory limits for RF <br /> exposure to members of the public. These RF field measurements are accurate, and meet FCC and <br /> MDPH guidelines. <br /> RF field theoretical calculations were performed by this consultant as issued in a report dated <br /> April 11, 2002. The results indicated a maximum potential increase of about 0.11 % of the <br /> maximum allowable (%MPE). The sum of existing and proposed theoretical RF fields would be <br /> significantly below FCC and MDPH RF exposure limits; that is,less than 0.3 percent. This means <br /> there could be over 300 additional similar installations, and still be below all regulatory limits for <br /> RF exposure. <br /> Based on my extensive experience with personal wireless services facilities,and the RF fields <br /> I have calculated and measured, it is my expert opinion that the current and proposed personal <br /> wireless services installations would comply with regulatory guidelines for RF exposure. <br /> 427 Amherst Street,Unit#11 <br /> Nashua,NH 03063 <br />
