Non-ionising radiation does not penetrate deep into the tissues but increases the risk of damage to the skin and eyes. Dependent on the energy and exposure time, non-ionising radiation can cause localised heating, or photochemical reactions can occur with possible permanent harm.
It's not totally harmless. Just orders of magnitude less than ionizing radiation.
- manmal 8y agoI generally agree with you, but not with the "does not penetrate deep into the tissues" part. Non-ionizing radiation includes frequencies like 980nm (near infrared) which penetrates 3 centimeters deep at ~15W: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4552256/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4552256/ Microwaves have wavelengths orders of magnitude longer than infrared light and can penetrate even deeper at the same wattage. It would IMO be VERY iffy to say that the possibility of photons emitted by a cellphone reaching the brain is zero.
