Model		RF emissions measurements from radio and TV broadcast towers sites in Colorado
Details		Power density measurements (0.1-3000 MHz) inside 161 homes in the Denver, Colorado area with 15 primary radio and TV broadcast transmitters in the area. The authors report that in addition to distance, elevation and line-of-sight significantly affected RF power density levels. They report measured values from nondetectable to 20.9 microW/cm2 (avg 2.6 +/- 4.0 microW/cm2), all below the general public exposure limit of 200 microW/cm2). House average power densities ranged from nondetectable to 6.7 microW/cm2 (avg = 0.8 +/- 1.0 microW/cm2). Average attenuation from outside to inside was 44 +/- 62 percent. Approximately one in four subjects had average interior levels greater than 1 microW/cm2. They authors suggest the use of global positioning could improve exposure assessment in future epidemiologic studies.
