The original testing on the dangers of microwave radiation were done by the US Navy, they are now considered flawed tests but the safety limits haven't been changed since all of our existing equipment is based on those safety limits.
It was great seeing the informed, grass-roots movement in the US trying to stand up to this but it's nearly always impossible to beat the big boys.
Check the small print in your mobile phone, the advice is clear, use the speaker and don't use the phone for more than a few minutes, they are aware of the dangers and 5G literally amplifies that danger.
