Scientists and researchers specializing in measuring the levels of radiation from mobile phones, that many models and devices on the market, emitting radiation beyond the limits of human health, which is allowed by the competent health and regulatory authorities. They said abuses were between 1 and 5 times the limits.

The findings came from an independent report by researchers and scientists at the RF Exposure Lab in San Marcos, California, a US Federal Communications Commission-accredited specialized center that specializes in measuring radioactivity from mobile phones and how much they reach the human body. He made a series of measurements at the request of the Chicago Tribune, which paid for the measurements. The full results of the study conducted by the Center in an investigation were posted on its website investigations, and confirmed that scientists and users are increasingly concerned that radio-frequency radiation from mobile phones may have adverse effects on human health, after it was found that 3G and 4G mobile phone models have the potential to exceed the US Federal Communications Commission (FCC) secure limits by up to five times, raising fears of damage to the 5G deployment during Coming years.

Sample test

Experts in the study tested 11 models of mobile phones on the market, including four models of Apple iPhone, iPhone 7, iPhone 8, iPhone 8 Plus, The iPhone X, and three models of «Samsung» are «Galaxy S8», «Galaxy S9», and «Galaxy G3». The sample included three Motorola smartphones: i5Play, G6Play, Blue, and the Vivo Blue.

Test method

In this study, the experts applied the method based on the guidelines and rules issued by the US Federal Communications Commission regarding the measurement of radiation from mobile phones, which is based on a standard known as the "specific absorption rate" or the standard "SAR", which is measured Radiation from the mobile phone reaches the human body, when the phone is at a distance of 2 to 5 millimeters from the body. This is the distance the phone is often placed when users put it in their pockets or belts. According to this criterion, testers are required to measure the amount of radiation the phone emits and is absorbed by the body and can be measured in tissues.

The test is usually carried out in a laboratory simulation environment, a liquid-filled tub consisting of a mixture of sugar, water and salt, which can absorb radioactivity from mobile phone in the same way as human body tissues, where the phone is placed between 2, 5, 10, And 15 millimeters of pelvis, when the test instrument is turned on, a robotic arm oscillates inside the pelvis, making a probe, a thin pen, dive into the pelvis for 18 minutes, measuring the radio frequency radiation levels absorbed by the liquid from the mobile phone, and repeating it several times.

tests results

Tests showed that the radio frequency absorption levels of the iPhone 7 were among the worst offenders, with the absorption rate higher than permitted by the US Federal Communications Commission's SAS standard two to four times, depending on the distance of the phone. Of the body. The three Samsung models showed a five-fold overshoot of the SAR standard in some tests, and Motorola phones showed similar irregularities.

The findings prompted researchers to say that older 3G and 4G mobile phones have the potential to exceed the FCC's safe boundary several times.

The experts also said that mobile phones are supposed to enter the position of "low energy" when approaching the skin and human tissues, because they are equipped with built-in sensors designed to measure the proximity to living tissue. At the distance specified in the safety standards, the energy you operate is reduced. When tested, Apple and Motorola do so at a reasonable level, but Samsung does not, and records high readings.


Reactions to the findings of this study varied. For its part, the US Federal Communications Commission said that the tests carried out are not comprehensive, such as those usually provided in the official compliance reports of the standards of the Commission, and that exceeding the safety standards by several times does not automatically mean the inevitable health damage to users, because the harmful effects actually appear at levels that increase 50x, as specified in the security standard.

However, the Commission takes the results of this study very seriously, and will carry out a study in the next three months to re-examine the safety tests on mobile phones and others, to reach a decision.

With regard to manufacturers, the Chicago Tribune reported that when Apple was informed of the results of the 100-page report, Apple objected to the results, saying it was not conducted in a way that evaluates iPhone devices in a way. True, Apple did not specifically disclose what it thought was a test error, or reveal how the company measures its phones for potential RF radiation exposure.

However, the researchers responsible for the study, re-tested the iPhone «devices» again and submitted 13 questions to «Apple», but did not respond to any of them, and instead issued a statement reiterating that the test results are inaccurate because the test was not prepared according to procedures Necessary to properly evaluate iPhone models. The statement confirmed that all iPhone models are fully certified by the FCC, and that Apple is committed to complying with all applicable radiation exposure guidelines and limits.

Samsung Devices

Samsung released a statement saying that Samsung devices sold in the United States comply with FCC regulations and that their devices are being tested according to the same test protocols used worldwide.

The iPhone 7 is the worst offender at 2 and 4 times the safety limit.
