Recently, the newspaper Chicago Tribune conducted a test and found something quite worrying: several devices (including iPhones) would be emitting radiation above the allowed by the 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, was concerned about the findings, and said it would carry out new tests of its own with smartphones to find possible disrespect for 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 cell phones tested by the FCC laboratory, both samples provided by the beneficiary and purchased by the FCC, produced maximum mean SAR values of 1g below the 1.6W / kg limit specified in the FCC rules. Therefore, all sample devices tested are in compliance with the exposure limits to population radiation / uncontrolled SAR average space of 1.6W / kg, with an average of 1 gram of tissue, as specified in 47 CFR Sn. 2.1093 (d) (2), and these tests produced no evidence of violations of any FCC rules regarding maximum levels of RF exposure.
For interested parties, the complete results can be seen in this PDF.
At the time of the publication of the test carried out by the newspaper, Apple contested the tests, saying that they did not follow the necessary procedures 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. Apple then contested the numbers again, saying that its own tests showed safe emission rates on its smartphones.
Which test is the most accurate / correct? Hard to say. The fact is that the FCC is putting its “face to face” by contradicting the figures found by the newspaper.
