Smartphones, including the iPhone 7 and Samsung Galaxy S8, emit radiation at levels higher than those that US regulators consider safe.
Mobile phones use radio frequency (RF) radiation to transmit signals. The frequency of known carcinogenic forms, such as X-rays, is much less common, but experts have wondered if these waves were harmful to humans.
As a precaution, US regulators have defined the maximum amount of radiation that devices can emit, but tests at the Chicago Tribune have revealed that the iPhone 7, the Samsung Galaxy S8 and many other models could exceed these limits .
For the FCC, the radiation limit for mobile phones reveals that devices should not release more than 1.6 watts per gram of tissue on average.
Radiation – even relatively low-frequency emissions such as radio waves used in mobile phone technology – can potentially penetrate the skin and damage DNA. This genetic anomaly can cause cancer and other health problems if levels and duration of exposure are significant enough.
Studies of people working near higher radio frequencies showed that they were at a higher risk of developing certain cancers.
Studies in mice have shown that radiation can increase the risk of heart and genital tumors, but it is strange that male mice exposed to radiofrequency have also lived longer than mice not exposed to radiation.
Until now, however, RF radiation has not reached the threshold of being considered a "possible carcinogen" for humans.
However, the FCC requires all smartphone manufacturers to demonstrate that their devices do not emit more radiation than they consider safe before they are placed on the market.
California did not trust these limits and smartphone security, like expert groups: the Environmental Working Group (EWG).
To examine each side, the Chicago Tribune has done its own testing by placing all 11 models of Apple, Motorola, Blue and Samsung smartphones in two different sizes – 5mm and 2mm. – Materials that mimic human tissue.
The FCC requires manufacturers to test phones anywhere, 5 to 15 mm away from the test body.
The study also tested phones at a distance of 2 mm, to simulate the distance between devices in the pocket.
From the pocket, the iPhone 7 emits 2 to 4 times more radiation than allowed by the FCC principles. At worst, the Galaxy S8's radiation was twice the legal limit, suggesting that the FCC test protocol is not enough.
The FCC said it will study the testing practices of smartphone companies.
