RF stands for radio frequency, and its radiation is a "nonionizing electromagnetic energy characterized by relatively long wavelength, low frequency, and low photon energy," according to the division of Environment, Health and Safety at Berkeley Lab. Radiofrequency energy includes radio waves and microwaves. Microwave radiation is considered a subset of RF radiation. Different RF bands are used in "aeronautical radio, navigation, broadcasting, and personal wireless communication services," according to EHS, while "specific frequencies are designated for industrial, scientific, and medical uses." The committee did not address whether the cause was intentional, who might have been responsible or what the motive might have been.
The pipeline does not have enough capacity to carry radio waves.
