Men in lead pajamas will be investigated after the Chicago Tribune tested several smartphones for radio frequency (RF) radiation. The newspaper found something that might be disturbing; The radio frequency radiation emanating from the Apple iPhone 7 not only exceeded the legal safety margin, but also doubled the amount of radiation that Apple's own testing showed that the device had leaked. This is based on requests from federal regulators made by the company.
The Tribune states that the FCC states on its website that any telephone approved for sale will never exceed the maximum level of radiation exposure considered safe. However, four iPhone 7 devices have been tested by the Tribune and all have emitted radiation above this level. The FCC responded to Tribune data by stating that it would start conducting its own tests in the next two months.
Samsung Galaxy S8 scores worse than 2mm phones
Tribune tests 1
1 different phones including iPhone 7, iPhone X, iPhone 8, iPhone 8 Plus, Samsung Galaxy S9, Samsung Galaxy S8, Samsung Galaxy J3, Moto E5 Play, Moto G6 Play, Moto E5 and BLU Vivo 5 Mini. Each of the phones was tested to see the amount of RF radiation that leaked 2mm, 5mm, 10mm and up to 15mm. The 2mm test was a dome to simulate how much radiation a person could get if he put his phone in his shirt or pants pocket. The tribune says that at this distance, most of the devices it tested exceed the high-frequency range of radio frequency radiation. Tribune recommends that smartphone owners refrain from carrying their phones in their pockets. Because RFID headset testing standards were created in the 1990s when people wore them to a belt clip, the FCC allows new phones to be tested for radiation up to 25 mm apart.
How radio frequency radiation compares to other types of radiation
The FCC radiation limit is "1.6 watts per kilogram average per gram of tissue". Tests reported by the Tribune find that the iPhone 7 exceeds this limit when tested at 2mm and 5mm distances. In many of the tests, the radiation level of the phone was twice the value the FCC considered safe. The iPhone 8 Plus came in at 1.6W / kg during its tests, while the Samsung Galaxy S9 did well at 15mm but failed at 2mm.
The worst result of 8.22W / kg belonged to Samsung Galaxy S8, which produces this amount of 2mm radio frequency radiation. Some Apple and Motorola phones went through a second round of modified tests based on feedback from their respective manufacturer; based on these results, the Moto G6 Play did very well (.25W / kg of 5 mm and .53W / kg of 2 mm). The BLU Vivo 5 mini broadcast test also came under FCC restrictions.
When Tribune presented Apple's results, the company told the paper how to activate sensors in the iPhone 7 that reduce the power of the device. But even after making the change, this model still emits too much radio frequency radiation. Apple has stated that Tribune tests "were inaccurate because the test setup did not follow the procedures required to properly evaluate iPhone models. All iPhone models, including the iPhone 7, are fully FCC certified and in every another country where the iPhone is for sale. After careful review and subsequent validation of all iPhone models tested in the report (Tribune), we confirmed that we are in compliance and meet all applicable… exposure guidelines and restrictions. "
Samsung responded to tests by doing the following new statement: "Samsung devices sold in the United States comply with FCC rules. Our devices are tested according to the same testing protocols used in the industry."
Although it is unclear whether exposure to radio frequency radiation may it can cause tissue problems at high levels, and the eyes and testicles are most at risk because they do not dissipate heat well. You may recall that last year, a study conducted by the National Institute of Environmental Health Sciences (NIH) / National Toxicology Program (NTP) found that men, mice blasted with cellphone radiation had a slight increase of the onset of a rare cardiac tumor. The fact that the test did not show a clear link between cell phones and cancer was underlined by the actions of the Chief Medical Officer of the American Cancer Society, Dr. Otis Brawley. Dr. Brawley told reporters, "I actually keep my cellphone to my ear."
While a new phone has to be tested for RF radiation before it can be released in the US, the manufacturer can choose the testing lab, Even worse, only one device has to pass the test so that millions more than a particular model can be sold.
