Hi, not really. Exposure to radiation is way higher during a 3+ hour flight, than during a normal day of using WiFI / 4G on your phone.

Yes, but we usually spend much more time in front of a laptop than on a plane. Why for example Switzerland or Austria have less high limits for Wi.Fi than Germany, or don't want at all allow its use in hospitals and schools? Meanwhile, there is so much evidence that EMF are not good for us. 5,24 GHz radiation interferes with natural radiation (Schuman resonance)...
