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. Microwave radiation is considered a subset of RF radiation. Radiofrequency energy includes radio waves and microwaves. If microwaves were used, the technology is not rare, and more than one country could be using it. The statement goes on to say "...this weapon is designed to bathe a target's living quarters in microwaves."
The statement gets on to say that the device is designed to bathe several countries.
