With the spread of smartphones, mobile phones have invaded our everyday lives. The forecast is that by the end of 2018, 4.9 billion people are connected to the mobile Internet, which appeared in 1997. In 2014, so-called mobinautas officially outnumbered the number of Internet users who have access to a fixed computer network.
The mobile internet uses radio frequency for connection, which is because our mobile phones emit electromagnetic waves. The potential danger to health has been of interest to science for several years.
A report recently published by the National Toxicology Program, a service linked to the US Department of Health, found that prolonged exposure of 2G and 3G waves to mice and mice is responsible for heart disease in animals.
The study, commissioned by the FDA – the US federal agency that evaluates and approves drug use and the influence of new drugs – took ten years to prepare. The RFI interviewed with American scientist John Bucher, one of the study designers.
According to him, animals were continuously exposed to radio frequency within the uterus as they were 5 or 6 weeks old. The rats were placed in a closed compartment where the waves, as they say, were randomly distributed.
Turn off your cell before bedtime
During the experiment, the animals were exposed to the waves for ten minutes. Ten more minutes followed. This is for 15 hours a day, which amounted to eight hours a day of exposure, Bucher explained to RFI.
The results, although for the time being, can not be compared to humans, are alarming: male rats exposed to high levels of radiation have developed cardiac tumors and there are indications that this exposure has also caused cancers in the brain and adrenal rodents.
This conclusion that there is a link between cell abuse and brain tumors is worrying scientists. Adolescents, addicted to their mobile phones, are exposed to a risk that has to take years to test people and therefore to support some sort of regulation.
"One of the biggest concerns we have is the teenagers who let their mobile phones next to the pillow always be connected, exposing the brain to the waves all night," the researcher recalls. Not to mention that in adolescence the body is in full swing and is more prone to external attacks.
There have been many studies in Europe on the subject, which explains the recommendation of scientists who are studying the issue of switching off the mobile phone at bedtime.
"In mice, we found more tumors in the heart perhaps because we exposed the entire body of the animals to the waves. In humans, the result will be the same in the brain as the cell is closer to the ear, "the American researcher explains." The relationship between exposure to electromagnetic waves and tumors in women has not been proven. in the preliminary results of the study published in 2016, was not explained.
Despite the evidence, it is not yet possible to show how radio frequency really works in the human body. Not to mention, the scientist notes that the same tests were not performed at the 4G frequency and Wi-Fi and new technologies are constantly changing and improving. Therefore, the need for further studies.
The American scientist remembers, however, that different frequencies are used for different actions on the mobile phone. "If you're using a new smartphone, you'll probably be using 3G or 4G for streaming and 2G for SMS." In view of many unanswered questions about the influence of radio frequency transmitted by mobile phones, the National Toxicology Program manufactures equipment that will allow them to change and adjust frequency more quickly during the tests.
According to the American scientist, it will be much easier to conduct animal experiments and draw conclusions in a few months. "It's not very different from the microwave, we did not do it before, because we were not exactly what we were looking for." We know now, "says Bucher.
