Modern technology changed our lives — they made us more mobile and, oddly enough, more dependent. Dependent on these four letters: Wi-Fi. How dangerous the radiation from Wi-Fi router, can I use wireless Internet and children what’s all the same threat on mobile phones are described below.
Wi-Fi is a standard for wireless communication. Today, wifi is used in almost all public places — parks, restaurants, shopping and entertainment centers, and Wi-Fi router, “distributing” Internet at home or in the office, doing work and communicating online comfortable and convenient. However, despite all the obvious advantages, wireless Internet wrapped in hundreds of myths and speculation. Some argue that radio waves emitted by a router, they provoke dangerous diseases, others believe that this achievement of civilization is absolutely harmless. Let’s deal!
Myth №1: Radio waves emitted by the router, dangerous
In fact: most are already familiar to us wireless devices operates in the same microwave frequency range. For example, 4G LTE mobile phones as well as microwave ovens operate in frequencies 2,5—2,7 GHz. Thus, the reason to distinguish radio waves from Wi-Fi-router, in a separate class of electromagnetic radiation, no. By the way, the wavelength of the wifi signal practically corresponds to the relic cosmic radiation, so if you are afraid your router, then in any case do not go outside without a coat of foil.
Radio waves can affect the body, only if you are in the vicinity of a powerful industrial source for extended periods of time (for example, somehow you were close with aviation radar and spent the night near him). The radiation power of home routers are incomparably lower and have a damaging effect on the cells of the body, they simply can’t. Besides radio waves of Wi-Fi are not directional in nature and are dispersed in the space uniformly, weakened in the exponential function of the distance (double the distance, four times as decreased the intensity of radio frequency radiation).
Myth №2: Any electronic device (wifi router included) are able to create an electromagnetic field, and it is harmful
In fact: at different times scientists have conducted hundreds of studies to prove the harm of electromagnetic radiation of household devices (including mobile phones and Wi-Fi routers). However, all the results say otherwise — proven harm no. A mobile radio is so firmly entrenched in our lives that even if it would be established an increased risk of developing certain diseases (he, mind you, not installed), to give them modern society is not. We breathe the air of cities, soaked in exhaust fumes, drinking water, subjected to chemical treatment, eating vegetables treated with pesticides and fertilizers. But despite this, life expectancy in developed countries over the last hundred years has increased significantly, which in turn, indirectly proves that civilization, with its inventions is not so dangerous to health.
The electromagnetic field is harmful to humans only at very high capacity with a long stay near a powerful industrial source such as a power line or a radar station. Thus, if there is prolonged exposure (eight hours a day for several years) with a strength of more than 0.2 microtesla, the risk of hematological and oncological diseases increases (at home to achieve a similar result you need every night for several years to fall asleep and Wake up in the arms of the router).
Myth №3: Wi-Fi router emits dangerous radiation
Actually: the intensity of the radiation of the router to the hundreds of thousands of times less than in the same microwave oven in your kitchen (and they remind, working in the same range), and it in no way can be considered dangerous to humans. If to speak about the background radiation associated with the operation of the circuits of the device, it is not more dangerous than the background from charging or power supply unit of a home cordless phone.
Mobile phone, by the way, in principle, has no background radiation that (if it is not, of course, dropped into a tank of radioactive waste). He has electromagnetic radiation, the harmful impact of which on the human body is not proven. Some studies have reported a change in the bioelectric activity of the brain under the influence of electromagnetic fields of mobile phone, however, these changes are reversible and their negative cumulative (cumulative) effect is not proven. In General when talking on the phone more likely to damage your health by losing concentration during conversation, for example, it can please a car crossing the street, or if he is a driver to get into an accident.
Myth №4: Pregnant women should not use wireless Internet
Actually: so how frequently dividing cells are most susceptible to external influences (due to the fact that a DNA molecule is most vulnerable at the moment of cell division), pregnant women should minimize exposure to drugs, ionizing radiation and other harmful factors. The lower the gestation, the more susceptible the fruit. However you need to remember that wireless devices do not produce ionizing radiation and their harmful effects on the fetus is not confirmed in scientific studies. It should also be noted that the fetus is pretty well protected from external influences he is surrounded by a layer of amniotic fluid, the walls of the uterus, pelvic bones, organs and abdominal wall. All these structures contain a lot of water, which effectively weakens radio waves.
Myth №5: Electromagnetic radiation harmful for children
In fact, of all the human tissues brain tissue is the most resistant to external influences. This is because the brain cells of a child at birth is already formed and throughout the life of almost fall. Thus, the DNA of brain cells is not in a vulnerable state, when an external impact may cause genetic defects, mutations, and tumors, in contrast to, for example, from the cells of the intestinal epithelium: they are divided even in adults, because the mucous membrane is to be continuously updated. Therefore, the intestinal form of radiation sickness develops when small doses of absorbed ionizing radiation and brain form only at the high (remember, radio waves do not apply to ionizing radiation). Multiply this natural resistance of the brain on unproven harm from radio waves, and you will receive virtually immune to radio frequency radiation the body called the “human brain”.
