There are two factors in electromagnetic radiation that determine harmfulness to humans: frequency and amplitude.
Within the electromagnetic spectrum, ranging from radio waves to visible light to X-rays, radiation from a certain frequency is potentially ionizing.Ionization means that an atom or molecule loses or gains an electron. When this happens in our cells, this can cause DNA damage and eventually lead to cancer. Photons (light particles and thus also ‘ WiFi particles ‘) need a certain amount of energy to bend those electrons away. The energy value of such a photon is determined by the frequency. The higher the frequency, the higher the energy that such a photon has.
Ionization is only possible when exposed to radiation at a frequency Of About 1000THz (somewhere in the ultraviolet).There are a lot of factors that come to mind. Different atoms have different ionization energy. The most important thing for this question is that ionization under the 1000THz is absolutely not possible (at any atom).
WiFi uses the 2, 450MHz and 5, 000MHz band.That is a factor of 200 000 lower and lies somewhere between radio waves and visual light in the microwave band. If you are not afraid of radio waves (which are continuous) and are not afraid of visual light (which are continuous), it makes little sense to be afraid of WiFi.
Non-ionizing radiation can be harmful if the amplitude is sufficiently high to warm up body tissue.Use a microwave oven without having to close the door (assuming it can), then your eye tissue and possibly other tissue will be burned. That’s what you’ll notice. A microwave oven also uses the same frequency band as WiFi (2, 450MHz), but the amplitude is much higher.
The only reasonable conclusion is that WiFi is most likely not harmful to health.You can never completely exclude it: There can always be a mechanism that we do not yet know that makes Sure that WiFi is still harmful. Observational studies also seem to indicate that there is no causal link between normal exposure to WiFi signals and negative health effects.
No, there is no indication that Wi-Fi is harmful to your health.
It works have with a very low power (between 0.2 and 4 watts).
Each radiation is in principle harmful to the body of living organisms.According to physics, however, four factors are important:
The frequency, the amplitude, the distance to the source of the radiation and the time that the radiation acts on the tissue.
Ordinary radio frequencies (short wave, radio, WiFi and mobile phone) are not harmful at a distance according to most experts, but no one will climb a radio station’s mast while the transmitter is still on.Fortunately, the danger of radiation decreases with the square of the distance so that if we do not stay at a distance there is probably no danger.
The fact that one recommends not to use mobile in an elevator is the fact that the cellphone maximizes its transmission power in an elevator to reach the mast and is also sitting right next to your head.In such a situation of minimum distance at maximum transmission power, it is certainly not impossible that during a call of a minute or so in an elevator, damage is given to your brain tissue.
As long as the WiFi router is working at meters distance from a person no health hazard will occur.
Since Bluetooth (BT) also works with about the same frequencies as WiFi, the same rules apply here.However, BT works with even lower power than WiFi, but on the other hand when using BT earplugs or headphones, the time one is exposed to radio radiation with these devices is rather long, which is the use of BT earphones again problems Makes.
Wifi warms up!
