Abstract |
The U.S. Environmental Protection Agency has been collecting broadcast signal field intensity data for over two years to estimate population exposure to this form of nonionizing radiation. Measurement data have been obtained at 373 locations distributed throughout 12 large cities in the U.S. and collectively represent approximately 11,000 measurements of VHF and UHF signal field intensities. A computer algorithm has been developed which uses these data to estimate the broadcast exposure at some 39,000 census enumeration districts within the metropolitan boundaries of these 12 cities. A median exposure level (that level to which half of the population is exposed greater than) of 0.005 micro W/sq cm time averaged power density has been determined for the population of the 12 cities studied, the cumulative population of which represents 18 percent of the total U.S. population. The data also suggest that approximately 1 percent of the population studied, or about 380,000, are potentially exposed to levels greater than 1 micro W/sq cm, the suggested safety guide for the population in the USSR. |
