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. 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." "I believe it's RF, radio frequency energy, in the microwave range," Lenzi told Scott Pelley. "Because it's China, because we have such a large trade relationship with them," Lenzi said.
