EPA and FCC measurements found radiofrequency levels exceeding FCC guidelines near the KYGO-FM tower on Lookout Mountain in 1986.

Plain English Summary

Summary written for general audiences

During the week of September 22, 1986, EPA and FCC personnel investigated radiofrequency radiation intensities near the Lookout Mountain antenna farms west of Denver, Colorado. Typical power densities near several area residences did not exceed 100 pW/cm², and the highest value along Cedar Lake Road was 580 pW/cm², which is below the 1000 pW/cm² FCC guideline. Near the base of the KYGO-FM tower, a 10,000 pW/cm² value was found and power densities exceeding 1,000 pW/cm² were measured over a large area in a residential area accessible to the public. EPA urged the FCC to order KYGO to correct the problem as soon as possible.

Finding

The highest value found near the towers along Cedar Lake Road was 580 pW/cm², which is below the 1000 pW/cm² FCC guidelines. However, near the base of the KYGO-FM tower, a 10,000 pW/cm² value was found and power densities exceeding 1,000 pW/cm² were measured over a large area. The areas exceeding the FCC guidelines are in a residential area and are accessible to the public.

In their words

“The highest value found near the towers along Cedar Lake Road was 580 pW/cm², which is below the 1000 pW/cm² FCC guidelines. However, near the base of the KYGO-FM tower, a 10,000 pW/cm² value was found and power densities exceeding 1,000 pW/cm² were measured over a large area. The areas exceeding the FCC guidelines are in a residential area and are accessible to the public.”
