There are many different frequency bands used by 5G for communications purposes. See tables here.
These are not generally a concern due to the lower power levels in use even if a given frequency might cause problems at a high power level. UV-C is considered ionizing radiation. Ionizing radiation uses frequencies which are far above visual light. Ionizing radiation (ionising radiation) is radiation, traveling as a particle or electromagnetic wave, that carries sufficient energy to detach electrons from atoms or molecules, thereby ionizing an atom or a molecule. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.[citation needed]
Gamma rays, X-rays, and the higher ultraviolet part of the electromagnetic spectrum are ionizing, whereas the lower ultraviolet part of the electromagnetic spectrum and all the spectrum below UV, including visible light (including nearly all types of laser light), infrared, microwaves, and radio waves are considered non-ionizing radiation.
The frequency of a household microwave oven is 2.4-2.5 GHz, while the frequency for optimal absorbency by water is around 10 GHz.
These frequencies cause the dielectric heating of water. This is why a fire control radar can kill a bird in flight. It is a question of range and power. Home microwaves are not set to 10GHz as this would not allow the microwaves to penetrate very far before giving up their energy. Your food would end up with a cold center and a super-heated surface.
Hope this helps.
