Electromagnetic waves are harmless.
The vast universe, boundless starry sky, the space of electromagnetic waves is infinitely light years compared with the space of the atmosphere, and countless extraterrestrial stars have various electromagnetic radiation sources, the density of which is not comparable to that of air. In space, the light radiation generated by the sun is very small, and the power of electromagnetic waves can be imagined. Communication between the atmosphere, lightning, radio stations and the whole world.
(letters), navigation equipment, etc. , and intentionally or unintentionally created interference waves intertwined, bustling, full of space, people live in the ocean of electromagnetic waves.
Electromagnetic waves are everywhere, and electromagnetic radiation sources can be divided into natural electromagnetic radiation sources and artificial electromagnetic radiation sources. Lightning, sunspot activity and cosmic rays all produce electromagnetic radiation, which is a natural electromagnetic radiation source. Artificial electromagnetic radiation sources mainly include all kinds of radio equipment, including industrial, scientific and medical equipment.
As for the harm of electromagnetic waves to the body, it should be negligible compared with air pollution, water pollution, food pollution, dust and other things. Those who work in high magnetic field and strong radiation environment for a long time have no occupational diseases caused by electric radiation. People who have lived under high-voltage lines for a long time have not seen anything unusual in others for decades, and within a safe distance, high-voltage lines have no effect on other creatures. The scientific department has never stopped discussing and studying the influence of electromagnetic waves on people. National electromagnetic wave safety standards: long, medium and short wave electromagnetic radiation is less than 10V/m, ultrashort wave electromagnetic radiation is less than 5V/m, and microwave electromagnetic radiation is less than 10MW/cm2. It is the result of predecessors and modern scientific research. All kinds of radio equipment approved by the state, such as mobile phones, walkie-talkies, indoor wireless phones, radio and TV transmitters, microwave and satellite communication devices, radar and radio remote controllers, as well as microwave ovens, high-frequency eye protection lamps, medical magnetic vibrators, helium arc welding machines, radio frequency electric heaters, high-frequency heat bonding machines, AC high-voltage transmission lines, switches, motors, generators, televisions and computers, all have electromagnetic radiation. Playing computer and watching TV and other close-range injuries to eyes are mainly not electromagnetic wave injuries, but fatigue injuries.
The electromagnetic wave naturally generated by objective conditions is a process of continuous attenuation. Although the artificially generated electromagnetic waves have greatly increased in recent years, this increase is negligible in the electromagnetic wave family. The serious electromagnetic wave pollution mentioned by the scientific community mainly refers not to the harm to people, but to the abuse, collision and accident of man-made electromagnetic waves, which needs to be strengthened.
Of all the electromagnetic waves that do harm to the human body, the mobile phone is the most serious, mainly because it is the most sensitive part of the human body when talking. If you are not afraid to use your mobile phone together, you should have no worries about others.
May you believe in science, respect science, not be afraid of electromagnetic radiation and fully enjoy life.
