I am trying to decide which phone to buy and I am very tempted by Fairphone, due - among other things - to its impact on the planet and people.
But also because of its SAR value, i.e., its emission of electromagnetic fields, and possible impact on health, since Fairphone appears to be much better than other phones, as illustrated by this graph, created by Tchat GPT (with its limit)
Hello, the info on SAR for FP5 and FP4 matches the one from their website. They also say that
Any mobile device with a SAR up to 2 Watt per kilogram (W/kg) for head and body and up to 4 W/kg for limbs, averaged over 10 grams of tissue, is considered safe for consumer use
So all the devices you listed should be considered safe.
You basically say you don’t trust researchers and health authorities. Because they say anything under the said limits is safe. Being lower below the limit is not any safer, because anything below the limit is harmless.
You body is constantly receiving many Watts of various types of energy (sun, heating, lighting, radios). It is also emitting Watts of energy (mostly heat). None of this radiation causes you harm until it overcomes a certain threshold.
Take the example of heat. Human skin cannot sustain e.g. 500 W/m^2 for a long time. But e.g. 10 W/m^2 is harmless. Does that mean 1 W/m^2 is “more harmless”?
