Smartphone Radiation Doesn’t Work the Way You Think
Of course, smartphones do emit radiation — and some emit more than others. And this type of radiation can be damaging in high enough concentrations. But the fact of the matter is that the iPhone in your pocket doesn’t emit the kind of radiation that can be dangerous in small doses, and it’s nowhere near powerful enough to cause damage otherwise.
To break it down further, smartphone radiation isn’t ionizing and smartphones don’t emit the same amount of radiation all the time. And even when they do emit peak levels of RF radiation, it’s a really weak amount anyway — even during a phone call when the device is directly against your head. That’s why they may be slightly harmful to rats, but not to people.
