Our habitat. What is the danger of 3G / 4G radiation?
Currently, no one has proven that exposure from cellular communications can provoke some serious illness, but the suspense is even more worrying. Many also notice increased fatigue when using smartphones, phones, tablets, modems and routers. Let’s try to figure this out?
The point of view of science Cellular communication is based on the use of microwave radiation of high-frequency waves (microwave). Favorite microwave ovens work on this principle. High-frequency waves can perfectly heat products. The same thing happens with body tissues that fall under their influence. This can have a certain effect on the human body, including nerve cells, brain neurons, and the lens of the eye. This issue is rather controversial, because there is very little information about such studies. “Too little time has passed to draw conclusions” – a replicated stamp.
But we need to do something now, and not wait for medicine to fix the “abnormal phenomena” decades later. What is there?

By the way, we have a more rigorous approach to this (at least by law), so local standards differ from European and American.
All cell phones, smartphones and other gadgets pass certain sales clearance. Currently, a mobile indicator of absorption of electromagnetic energy by humans, SAR, has been developed for mobile phones. You can see it in the phone’s specifications or search the Internet. If the indicator is below 1 W / kg, then there are no negative consequences for the human body. Its has most good mobile phones. (By the way, the first mobile phones had a coefficient of 5. And this, I think, was not particularly “advertised.”) If the indicator approaches 2, the tissue temperature rises by 0.3 degrees after a long exposure. Indicator 10 is able to raise the temperature to 37 degrees. Significant tissue damage, such as a burn, threatens those who are exposed to 50-100 BT / kg. It turns out that there is no reason for concern? Or is there “no smoke without fire”?
Subjective observations and common sense. Smartphones are always with us. Photo: Depositphotos It is not only a matter of distant probable negative consequences from telephone radiation. When working with your favorite smartphone (or even a laptop) for a long time, you may experience not very pleasant sensations in your head from 3-4G waves (or even Wi-Fi). In some cases, the head may hurt, general fatigue may occur, even psychological depression. In fact, it is precisely these symptoms that are of concern, since they interfere with normal work and life.
They can also prompt the idea of the general “uselessness” of cellular waves. In any case, it is better to limit the potentially harmful effects on the body than to argue that it does not exist. If we reduce the impact indicators to a simple scheme, then three points will be important: the duration of the work, the distance to the source, and the power of its radiation. Photo: Depositphotos Duration of work: try to be at the computer and smartphone just enough so as not to experience excessive fatigue. Most likely, we are talking about a few hours. The most dangerous distance is direct contact with your head. Half a meter is already better, and a distance of several meters can be said to be “practically safe”.
If possible, get as far away from the negative source as possible. Power depends on the type of waves, as well as the power of the transmitter device. Radiation from 3G / 4G communications is the most powerful. In second place we put Wi-Fi. Tires not so much, almost no effect, but you may well feel it with prolonged use. In the first place for safety – wires. In the next part, we will move from theory to practice in protecting against potentially harmful 3G / 4G exposure.
