A new survey of radiation levels released by smartphones has put some smartphone manufacturers on the defensive.
The Chicago Tribune and a team of scientists have conducted studies on various iPhone and Samsung Galaxy devices, including iPhones 7, 8, 8 Plus and X, as well as Galaxy S8, S9 and J3. In tests, which also included Motorola and SSB phones, scientists examined whether phones emitted more radiation than the Federal Communications Commission (FCC) guidelines allowed.
These guidelines are used to measure safety with a ratio called Specific Absorption Rate (SAR). According to the guidelines, any phone with an absorption rate of 1.6 watts per kilogram of human tissue is considered dangerous.
It should be noted, however, that the FCC has made it clear that even at 1.6 watts, this absorption rate would not be harmful to health.
Yet RS is important. And during tests, Chicago Tribune scientists found that the iPhone 7 was performing among the poorest, with absorption rates sometimes up to twice the level recommended by the FCC in RS.
The same is true for Samsung's Galaxy phones, which also recorded above-standard absorption rates. According to the testers, the Galaxy S8 had a breathtaking reading of 8.22 W / kg.
But before anyone panics, there are some pretty important caveats in these tests. On the one hand, even the Chicago Tribune acknowledged that the tests were a "worst case scenario" and that the same radiation levels would not likely occur in reality. In addition, the FCC stated that the test information provided by the manufacturers was more complete and therefore probably more accurate.
This is an important element in all of this. Despite the Tribune tests, the FCC has certified that the phones have safe exposure levels consistent with its guidelines. On its own website, Apple lists the exposure levels of its iPhones. The iPhone 7 that seems offensive has a 1.19 exposure level, according to Apple. The iPhone 8 has achieved a level of exposure of 1.2. In any case, they are below the guidelines.
According to AppleInsider, who spoke to an Apple spokesperson about this, the company believes the Tribune's tests are "inaccurate, because the test setup does not conform to the procedures needed to correctly evaluate the models. iPhone ".
The company added that it was confident in meeting the standards.
Of course, radiation is a concern. The more people are exposed to radiation in their lives, the more likely they are to contract cancer and other adverse health effects. But again, the FCC guidelines are designed to protect humans, even when levels are higher.
Nevertheless, the FCC has stated that it takes seriously all issues related to radiation and its policies. The agency said it will review the results in the coming months to determine whether the initial levels of radiation exposure are really accurate.
