We tested popular cellphones for radiofrequency radiation. Now the FCC is investigating.
The Apple iPhone 7 was set to operate at full power and secured below a tub of clear liquid, specially formulated to simulate human tissue.
With the push of a button, a robotic arm swung into action, sending a pencil-thin probe dipping into the tub. For 18 minutes, it repeatedly measured the amount of radiofrequency radiation the liquid was absorbing from the cellphone.
This test, which was paid for by the Tribune and conducted according to federal guidelines at an accredited lab, produced a surprising result: Radiofrequency radiation exposure from the iPhone 7 — one of the most popular smartphones ever sold — measured over the legal safety limit and more than double what Apple reported to federal regulators from its own testing.
The Federal Communications Commission, which is responsible for regulating phones, states on its website that if a cellphone has been approved for sale, the device “will never exceed” the maximum allowable exposure limit. But this phone, in an independent lab inspection, had done exactly that.
The Tribune tested three more brand-new iPhone 7s at full power, and these phones also measured over the exposure limit. In all, 11 models from four companies were tested, with varying results.
