In modern society, mobile phones have become an important part of life. Without them, you will have trouble breathing, lose your appetite, and don’t know where to put your hands or where to look when you go out to play. However, in recent years, I don’t know when it started, but a large number of articles about mobile phones causing cancer have appeared in the circle of friends, and they have been highly sought after and forwarded by parents, aunts and uncles at home. Some so-called "experts" also claim that placing your mobile phone on the bedside to charge while you sleep can emit radiation and easily cause cancer! But is this alarmist or just nonsense? Let me tell you slowly. We talk about mobile phone radiation every day, but what exactly is radiation? Radiation is the process by which an object radiates energy by releasing electromagnetic waves or particles. It travels extremely fast, equivalent to the speed of light. If you know a little bit about physics, you will understand: In fact, everything in the world, except objects at absolute zero, has heat and will radiate heat outwards. This is thermal radiation. If we want to see objects, we must have light. Whether it is lamplight, sunlight, or any other light, it is essentially a kind of radiation. When we bask in the sun every day, there is a large amount of radiation in the sunlight. In other words, radiation is everywhere in the environment we live in. If I could be "shot" to death by a mobile phone, I would have been blasted into pieces by the sun long ago! As we all know, the higher the frequency of electromagnetic waves, the stronger their penetrating power, the stronger the energy they carry, and naturally the greater the damage they cause to the human body. The lowest frequency of visible light is red light, which has a frequency of 10^14HZ. The maximum radiation frequency of a mobile phone is generally 300GHZ, which means that the frequency of red light, the weakest energy in visible light, is more than 300 times the frequency of the highest-power mobile phone. Generally speaking, the skin area of the human body exposed to natural light does not exceed one-fifth. That is to say, the electromagnetic radiation energy intensity you receive when you are fully dressed and walking in the bright sunshine is at least 60 times that of the electromagnetic radiation energy intensity you receive when you are naked and snuggling with a mobile phone and falling asleep. If the electromagnetic waves generated by mobile phones are capable of penetrating the skin and reaching the human body, causing cell damage, we who are so fragile would have long been blasted into pieces by the sunlight and light that shines on our bodies every day! Maybe using sunscreen and a parasol is more helpful in preventing cancer and maintaining health than staying away from mobile phones. |
