I know what you are saying that its all around us. But its like saying who cares Im exposed from other forms of radiation. By that logic then smog is bad right I cant avoid it, so is smoking so its ok to start smoking because Im going to be exposed to bad air quality anyways. Another example is that fat is in all foods there is nothing I can do about that so I guess its ok to eat McDonalds and super size everything. Im going to eat fat either way right?
You cant avoid these things but you can limit yourself to them. You dont have to be paranoia about them either. External sources or radiation such as satellite communication and even cell towers arent that bad. As the signal propagates air, foliage, other signal and their harmonic resonance will all interfere with the signal and it will degrade the signal strength very rapidly. If you talk on your phone for 3 hours a day and the antenna is only 0.5 inches away from your head, I would tend to think it might affect you in some way. There have been other studies about cell phone use with different conclusions. Im not saying that everyone should stop using them but I think moderation is the key.
The point he is trying to get across to those who cry and complain about being exposed to radiation have no real clue of what they are being exposed too. He is not saying that it's ok but, simply making you aware of such things.
