Abstract The report describes a series of measurements made to determine radio frequency exposure from television and FM broadcast stations located on Mt. Wilson to areas near the tower bases and within about 2,000 feet. Portable broadband survey instruments and a spectrum analyzer with dipole antennas were employed in these measurements and used in a comparison of indicated radiation levels and assess difficulties or peculiarities of the specific types of equipment. Maximum ground level exposure values were in the 1-7 mW/sq cm range. Intensities of about 0.1 mW/sq m were measured inside the Mt. Wilson Post Office which is located in the immediate vicinity of a large number of towers. It was found that wide ranges in exposure could occur over very small geographic areas revealing the potential for significant uncertainties in predictive modeling.
