@rysiek My concern is with legitimate debate ceding the spotlight to outrageous
conspiracies.
https://en.wikipedia.org/wiki/5G#Political_opposition
With regards to health specifically there is this public letter from hundreds of real doctors and other scientists:
https://www.5gappeal.eu/signatories-to-scientists-5g-appeal/
Now, if the authors of that appeal are linking a (legitimate) scientific article about negative impact of microwave radar on human health in the context of 5G, this clearly demonstrates that they have no idea what they're talking about.
A typical radar has power measured in thousands of Watts. A microwave ovens are 800-900 Watts. A typical 5G cell is 250 milliWatts. A typical WiFi is 20 milliWatts.
> why are radiation levels set lower in some countries than others
Because lawmakers in different countries are pressured by different lobby groups.
In fact, every stone on the planet contains some radioactive elements and their concentration is very different. If you have more granite in your area, you background radiation levels will be higher - see map for UK as an example.
