Chicago Tribune Claims iPhone Radiofrequency Radiation Levels Measured Higher Than Legal Safety Limit in Tests

The Chicago Tribune recently launched an investigation into the radiofrequency radiation levels output by popular smartphones, and found that some of Apple's iPhones are allegedly emitting radiofrequency radiation that exceeds safety limits.

According to the newspaper, it contracted an accredited lab to test several smartphones according to federal guidelines. iPhones were secured below clear liquid formulated to simulate human tissue while probes measured the radiofrequency radiation the liquid absorbed.

Apple officials declined to be interviewed, and asked The Chicago Tribune to submit questions in writing, which were not responded to ahead of publication. Apple later shared a statement that again said the testing was inaccurate "due to the test setup not being in accordance with procedures necessary to properly assess the iPhone models.

""All iPhone models, including iPhone 7, are fully certified by the FCC and in every other country where iPhone is sold," the statement said. "After careful review and subsequent validation of all iPhone models tested in the (Tribune) report, we confirmed we are in compliance and meet all applicable ... exposure guidelines and limits."

The FCC, meanwhile, said that it is going to be doing its own testing over the next couple of months.

"We take seriously any claims on non-compliance with the RF (radiofrequency) exposure standards and will be obtaining and testing the subject phones for compliance with FCC rules," agency spokesman Neil Grace said.

A Radio Frequency Exposure Test Finds an iPhone 11 Pro Exceeds the FCC's Limit

A test by Penumbra Brands to measure how much radiofrequency energy an iPhone 11 Pro gives off found that the phone emits more than twice the amount allowable by the U.S. Federal Communications Commission.

Ryan McCaughey, Penumbra’s chief technology officer, said the test was a follow up to an investigation conducted by the Chicago Tribune last year.
Penumbra used RF Exposure Labs, an independent, accredited SAR testing lab for the tests (The Tribune also used the San Diego-based lab for its investigation).

There are reasons to take the results with a grain of salt, however.

More notably, when the FCC conducted a follow-up investigation after the Tribune published its story, the agency did not find evidence that any of the phones exceeded SAR limits. That said, while the Tribune and Penumbra both used off-the-shelf phones, the FCC largely tested phones supplied by the manufacturers, including Apple.

Ultimately, however, what’s needed most is for more robust and comprehensive RF exposure testing from the FCC. But don’t hold your breath for that to happen any time soon. “The matter of changing the limit is more complicated,” says McCaughey. “It’s hard to define what’s a safe limit. There’s no consensus on what safe limits are.”
