I havenât read any of the links you show. My experience is working in the Royal Navy as a Radio Electrician around GHz signals of immense strength for radar. Sure we switched of the radar to climb the masts but thatâs it.
People make money from other peopleâs attention, what a âwasteâ of attention 
Sure pollution is a technical term for unwanted, as is waste.
One personâs waste is anotherâs resource, there is no actual waste.
My view is that probably all the links would reveal unwanted and irrelevant information, expressed to gather concern and effectively 100% 
Note that if it wasnât for âdamageâ to our cells there would be no mutation and itâs that mutation that produced mankind, we are still mutating from radiation but as mentioned the damage from sunshine has billions of times more effect than that of a mobile phone in your pocket all day, or a router in the room 24/7
The only issues are a slight warming possibility if held against any part of the body, as pointed out it has no ionising or cell effect.
When the network signal is low the phone pumps out more power to search.
Compare the heat from the phone with a bad signal and the heat when you are close to the transmitter. They play together ~ more radiation from the network, less from the phone, less from the transmitter more from the phone.
Once you adopt the road that all around you is damaging it is then worth looking at what is inside, the fear and stress.
Extra Low Frequencies ~ Radio frequencies they are all relative.
There was a chap in England, Rugby who lived near a 15KHz BBC Radio1 transmitter that could be picked up in New Zealand. It was so powerful he laid wiring in his attic and ran his electricity from the EMF in the air, until he was caught.
15KHz or 420,000,000,000KHz ???
Remember the sun provides 1KW/m2 which I am using to charge my batteries.
Certain frequencies will resonate with certain objects and some will resonate with cells making them vibrate and get warm. X-rays are so energetic and so small that then can and do rupture skin cells.
If you cut your hair to all the same length you will pick up a lot of the same frequency and despite it not causing skin cancer it is a bit like brain washing.
