No problem! Sadly, from my experience, if someone actually fears 5G, they are usually long gone. Any sane person would understand that (a) if mobile phone radiation would be actually harmful, we'd see massive amounts of damage already since over the last 30 years we went from no phones to everyone has a phone on them and (b) if it was harmful, it wouldn't be legal.
So people who still think that "This iteration of mobilie phone signal will surely kill us", are usually not part of the rational world anymore.
Another interesting fact: Phone signals need to make the trip both ways, from the tower to your phone and back. Signals lose their strength by the qube. So in 10m distance, the signal only has 1/101010 = 1/1000 of the strength as it does in 1m distance. In 100m distance we are talking about 1/1 000 000 of the strength as in 1m distance.
So if you are afraid of the radiation, it should be the radiation of your phone, not the radiation of the tower that you need to be afraid of.
So logically, in that case, don't own a phone and you are fine. But that is something even hardcore anti-5G folks aren't willing to sacrifice.
Also: Older phones and older standards (2G/3G) have a much higher radiation output than newer ones. Reason being that outputting radiation means consuming battery life, so the phone makers try to optimize the radios to output as little radiation as possible to conserve battery.
Another thing regarding the singal roundtrip: The farther away the tower is, the more radiation output from your phone is required to keep the signal. So shorter distances to the next tower means you are exposed to much less radiation coming from your phone.
Lastly: To believe that 5G, vaccinations or any of that stuff is harmful means that you have to believe that the government purpously harms the inhabitants and lies about it. This in turn means that every expert is part of the conspiracy and any evidence is a lie. If you are so far gone from reality, there is no argument that can bring you back.
