The rise of mobile devices has led to the gradual entry of WiFi signal amplifiers into thousands of households. And in the near future, perhaps we're going to live in Aseadis, a Wi-Fi-filled world. So we can't help but ask, is Wi-Fi really harmless? If not, how do we prevent the harm it does?
The answer is, as many people think, that Wi-Fi is harmless. But why? Take the microwave oven to make a comparison, first of all, Wi-Fi radiation intensity is 100,000 times weaker than microwave oven. Second, microwave oven microwave is directional, the voltage is very high, Wi-Fi radiation is not directed, the voltage is also much lower. It's like a spot-fire paper, where sunlight gathers and directs on the sheet, and the piece is lit.
And Wi-Fi follows the law of square inverse ratio in physics. This law means that when the distance is doubled, the energy is reduced by a quarter, which means that the energy of Wi-Fi decays rapidly as the distance increases. So don't believe the wireless router, which is advertised to cover an extra wide area, because even if the power is increased, the signal will decay very quickly.
In fact, mobile phones have a greater impact on the body than Wi-Fi radiation. Because using a mobile phone is usually very close to the brain, you don't have to stick to a router when using Wi-Fi instead. Experiments have shown that a phone call takes only 20 minutes and is absorbed by the body far more radiation than Wi-Fi is used for a year.
From the above introduction, Wi-Fi has a really small impact on the human body, so you can rest assured to use. But some friends say, no, the rapid development of science and technology, now harmless does not mean that the future will be harmless. So if we're going to defend against these Wi-Fi radiation?
