JULES COHEN 3 ASSOCIATES, P.C. CONSULTING ENGINEERS 37 WASHINGTON, D.C. 20036 s ENGINEERING STATEMENT ELECTROMAGNETIC FIELD STRENGTH SURVEY SPRINT CELLULAR COMPANY STATION KNKA293 CARRBORO, NORTH CAROLINA Electromagnetic Feld strength measurements were made by the undersigned at the transmitting site of Domestic Public Cellular Radio Telecommunications Service station KNKA293. The measurements were made on April 28, 1994, on behalf of Sprint Cellular Company, licensee of KNKA293. Locations on the cell site grounds, both inside and*outside the tower, and in the equipment shelter were surveyed to determine the levels of radio-frequency energy present. Data collected during the survey were evaluated against two standards which establish the maximum levels of radio-frequency energy to which humans may be exposed without known harmful biological effects. The two standards are American National Standards Institute (ANSI) C95.1-1982 and ANSLInstitute of Electrical and Electronics Engineers (IEEE) C95.1-1992. ANSVIEEE C95.1-1992 is the revision of C95.1-1982. The protection guide levels specified in ANSI C95.1-1982 have been adopted by the Federal Communications Commission as the acceptable levels of human exposure to RFR. The FCC currently is considering adoption of the revised standard and most likely will do so in the next twelve months. By evaluating the survey data against both the existing and revised standards, there should be no need to repeat the survey effort at such time as the FCC adopts the revised standard. Survey measurements were made at representative locations on the ground at the cell site, both buh md outside the tower fence, and inside the equipment shelter. The exposure level at each location w veyed was below the sensitivity threshold of the measurement instrument and well below the exposure limits 'established by either standard Further discussion of the survey follows.
