Yes, there were. But not at the number concerning 5th Generation, which opens up new frequencies all the way up to 90ghz which will be concentrated and directed. The same frequencies that are used by the military for crowd dispersal. Nevertheless, these frequencies have for 60 years been studied on and show negative biological, cellular effects with non-thermal radiation. It isn’t a controversy between the consumers and the telecommunication industry, though they fastrack state legislature in so muniipalities are not allowed to prevent small cells but a controversy between telecommunication industry backed (funded) scientists and no-conflict of interest independent scientists. Out of 1450 studies concerning emfs, hundreds on non-thermal effects, the independent scientists show that over 75% of the studies, all peer reviewed manu double blind placebo that there is negative biological effects on ALL life forms. Bees, insects, plants, animals and humans. As for the industry backed they illustrate that around 68-72% have no biological effects and are safe. Read the studies I listed below, there are thousands, and see if they are safe longterm. 20 years from now we will have hundreds of new rare brain tumour and cancer metastasations that rarely existed before the proliferation of EMF smog today. We are dosed 16 quintillion more times in artifical radiation than we were in the 1980’s.

There were, but I don't remember this many as I'm seeing for 5G. I wouldn't necessarily say that means it's less safe though
