Radiation is energy radiated in the form of rays, waves or particles. Either ionizing radiation or non ionizing or indirect ionizing. Ionizing is strong enough to remove electrons from orbiting an atom leaving the atom charged or ionized.

Indirectly ionizing radiation from neutral particles deposits energy into the medium through a two step process.
Ionizing, indirect ionizing and non ionizing radiation cause damage to DNA. 5G is a form of high frequency radio wave, 6G is even higher frequency and both are described as non ionizing radiation. An example of indirect ionising radiation is photons.
What is known about various ionization radiation types is the response of particular tissue to the damaging effect of radiation. This is called the effective dose and it incorporates a tissue weighting factor which is a measure of absorption.
“Because of this ‘resonance’ phenomenon, RF safety standards have taken account of this frequency dependence of whole-body human absorption, and the most restrictive limits on exposure are found to be in this frequency range (the very high frequency of “VHF” frequency range.”.

“I found a correlation between the degree of severity of hygienic regulation of levels of radio frequency electromagnetic fields for population, the main sources of which are mobile (cellular) communication systems, and the lethality rate from COVID-19 in various countries.”

We focus here on human health effects, but also note evidence that RFR can cause physiological and/or morphological effects on bees, plants and trees (3–5). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6701402/
