Basically, a microwave leaks around 10mw/cm2 few cm away give or take so you can make that as a reference (unhealthy). or you can measure RF few cm away your WiFi router also those values are not healthy.
Yes, these values are amazingly high as the standards setting bodies are miainly taking the industry view. eg. head of FCC in America is a telecoms lobyist appointed by Obama after giving a large donation to his political campaigning!
Regarding 5-G. I hear it cited that the problem is that its range is 30Ghz to 300Ghz. This is an RF frequency...correct? So if we are trying to pick up and damaging effects of 5-G we should use RF scale not EMF...correct?
My 4g phone sitting next to my bed was hitting spikes of 500 mW/M2 at like 4:30am. Phone was totally idle and would hit these random spikes then go back down to ambient range. My EMF-390 meter was 18 inches from my phone and my phone was about 3 feet from my head. This seems pretty high for my phone being idle and at this time in the morning. There is not any 5-G in my neighborhood yet but I wonder what kind of reading to expect when it does arrive.
