This recent British newspaper piece* is somewhat opinionated, but includes facts about German concerns about health risks. This Wikipedia link currently provides allegedly-scientific counterpoint. [“Jane you ignorant slut!”]
One thing possibly hinted at in the German report is the cumulative effect of ALL the electromagnetic radiation we now live amid (“electrosmog”?). We’re usually told about their “safety” one at a time, but what about altogether?!! One smokestack or factory-farm, car or burnt forest or clearcut, doesn’t cause Global Warming, but millions do, after all!
