The strength of those signals is very, very low. WiFi around -60dBm or lower most of the time and the cellular signal where I go is usually well below -80dBm. For comparison, the power received from Earth's nearest star Alpha Centauri A is on the order of -50dBm. If I'm concerned about WiFi and cellular signals I should be positively freaked out about natural sources of em radiation.
But having a couple watt transmitter pressed against the side of your head might be something to think about. Still, it is non-ionizing radiation and aside from the possibility of localized heating, which you would likely notice (I think?), what's going to cause cancer? Some previously unknown (to me) phenomenon?
- jobigoud 8y agoEarth's nearest star is the Sun :-) Which incidentally also emits ionizing photons in the UV zone.
- geomark 8y agoOk smarty. But you can choose to go outside only at night when the Sun isn't in the sky. But the sky is filled with other stars day and night. So you can never go outside if you are afraid of em radiation as weak as that emitted by WiFi hotspots or cellular phone towers.
