Recently, the newspaperChicago Tribuneperformed a test and found something quite worrying: several handsets (including iPhones) would be emitting radiation above the allowable United States Federal Communications Commission (Federal Communications Commission, or FCC).
Of course, the story would have consequences: Apple and Samsung were sued; The FCC, of course, expressed concern about the findings, and stated that it would conduct new smartphone tests to find possible breaches of the legal limit on the radiation index. And these tests were done.
The commission tested several devices (iPhone 7, iPhone X, iPhone XS, Vivo 5 Mini, Moto e5 Play, Moto g6 Play, Galaxy S9 and Galaxy J3) and the results were satisfactory.
All FCC laboratory-tested cell phones, both samples provided by the FCC and purchased by the FCC, produced maximum SAR average values of 1g below the 1.6W / kg limit specified in FCC rules. Therefore, all tested sample devices comply with the spatial average SAR exposure / uncontrolled radiation exposure limits of 1.6W / kg, averaging 1 gram of tissue, as specified in 47 CFR Sn. 2.1093 (d) (2), and these tests yielded no evidence of violations of any FCC rules regarding the maximum RF exposure levels.
For those interested, the full results can be viewed in this PDF.
At the time of the release of the test conducted by the newspaper, Apple contested the tests, stating that they did not follow the procedures necessary to measure the level of radiation emitted by iPhones. After the declaration, the Chicago Tribune decided to redo the measurements with the procedures recommended by the company, which generated similar results. Ma then contested the numbers again, claiming that their own tests showed safe emission rates on their smartphones.
Which test is the most accurate / correct? Hard to say. The fact that the FCC is slapping its face by contradicting the numbers found by the newspaper.
