This is the issue. There will be billions spent on 5G but no one wants to invest in doing an extensive reliable study that would perhaps cost 0.1% of total cost. Lobbyist have already convinced government that there are no health threats due to 5G. I would ask how you can make that kind of assertions when 5G isn't even deployed or no reliable citable studies have been done. Now Russia factor will make things even more worse because US will vehemently assert that there are no threats only because Russia is saying other way. There is a low probability of health issues but if there is one the cost would be huge and effect large part of generation. It's like selling radioactive toothpastes in late 1900s. No one thought there was a health threat in putting radium in something you brush your teeth with.
