What is radiation? Does the radiation of the communication base station affect people?
Radiation Radiation defines all objects in nature. As long as the temperature is above the absolute temperature of zero, they will constantly transmit heat outward in the form of electromagnetic waves. This way of transmitting energy is called radiation. The energy emitted by an object through radiation is called radiant energy, or radiation for short. An important feature of radiation is that it is "equivalent." No matter the temperature of the object (gas) is high or low, it radiates outward. Object A can radiate to Object B, and at the same time, Object B can also radiate to A. This is different from conduction, which is unidirectional. The heat effect occurs when the radiant energy is absorbed by the body, and the radiant energy absorbed by the body is different, and the temperature produced is also different. Therefore, radiation is an important way to convert energy into heat. Radiation is radiated outward in the form of electromagnetic waves. It spreads energy in the form of waves. Both radio waves and light waves are electromagnetic waves. Their propagation speed is very fast, the propagation speed in vacuum is the same as that of light waves (3×1010 cm/sec), and it is slightly slower in air. Electromagnetic waves are composite waves composed of waves of different wavelengths.
Its wavelength ranges from cosmic rays of 10E-10 microns (1 micron = 10E-4 cm) to radio waves with a wavelength of several kilometers. Gamma rays, X-rays, ultraviolet rays, visible light, infrared rays, ultrashort wave and long wave radio waves all belong to the scope of electromagnetic waves. What is visible to the naked eye is a very short section of electromagnetic waves, which is called visible light from 0.4-0.76 microns. After the visible light is split by the prism, it becomes a light band composed of seven colors of red, orange, yellow, green, cyan, blue, and purple. This light band is called the spectrum. Among them, red light has the longest wavelength, and purple light has the shortest wavelength, and the wavelengths of other colors are in between. The wavelengths longer than red light (>0.76 microns) include infrared rays and radio waves; those with wavelengths shorter than violet light (<0.4 microns) include ultraviolet rays, gamma rays, X-rays, etc. Although these radiations are invisible to the naked eye, they can be measured with instruments. The wavelength of solar radiation is mainly 0.15-4 microns, of which the maximum radiation wavelength is 0.5 microns on average; the ground and atmospheric radiation wavelengths are mainly 3-120 microns, of which the maximum radiation wavelength is 10 microns on average. It is customary to call the former short-wave radiation and the latter long-wave radiation.
People who work, study, and live in an environment where radiation sources are concentrated are prone to insomnia, dreams, memory loss, weakness, and weakened immunity. The growth rate of cancer cells is twenty-four times faster than normal people. How far is the radiation from us, in our living environment, radiation is everywhere! Household appliances: TVs, refrigerators, air conditioners, microwave ovens, vacuum cleaners and other office equipment: mobile phones, computers, copiers, electronic instruments, medical equipment, etc. Home decoration: marble, laminate flooring, wall paper, paint, etc. Peripheral environment: high-voltage lines, substations, televisions (Broadcasting) Natural environment such as signal transmission towers: how to avoid electromagnetic radiation pollution by sunspots. With the rapid development of science and technology, various technological products and household appliances have entered people’s lives, all of which have greatly improved It has improved people’s work efficiency and improved people’s lives. I can’t imagine what would happen to people’s lives without these live devices?
However, as the high-voltage electricity and transmission towers around the city are getting higher and higher, and there are more and more electrical appliances in the home, people feel convenient and at the same time are hurt. At present, electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. What would happen to you if one day, the house you live in is suddenly told that it is exposed to severe electromagnetic radiation? Among these many household appliances, can you find out which ones have higher radiation levels? What is electromagnetic radiation? From a professional point of view, electromagnetic radiation is a phenomenon in which energy propagates through space in the form of electromagnetic waves. Almost any electrical appliance in our home generates electromagnetic radiation. Such as microwave ovens, TVs, computers, mobile phones, etc.! What is the difference between electromagnetic radiation and electromagnetic radiation pollution? In fact, electromagnetic radiation and electromagnetic radiation pollution are two concepts. Any charged body has electromagnetic radiation. When the electromagnetic radiation intensity exceeds the national standard, it will produce negative effects and cause different diseases and harms to the human body. This part exceeds the standard electromagnetic field intensity. Radiation is called electromagnetic radiation pollution.
What is the impact of mobile phone base station radiation on the human body? This is a relatively common phenomenon, and mobile phone base stations are installed on many residential buildings in the urban area. Some citizens worry about whether the electromagnetic radiation generated by such devices will cause harm to the human body. In fact, there is no need to worry about this issue. The radiation of mobile phones is different from the radiation of mobile phone base stations. Generally, the electromagnetic radiation value of a mobile phone is between 0.03-0.7, and the radiation value of a mobile phone base station is 10 microwatts. The radiation value generated by a mobile phone base station is not much higher than the value of a mobile phone! In addition, electromagnetic radiation is the closer the distance, the longer the exposure time, the deeper the damage! The mobile phone base stations installed on the roofs of our general residential buildings are a safe distance from us, so everyone can rest assured!
What harm does electromagnetic radiation cause to the human body? Because everyone's physical resistance is different, each person will have different levels of symptoms. Generally, electromagnetic radiation pollution can cause central nervous system problems such as headaches, insomnia, and arrhythmia. At the same time, it may affect the eyes of some people, such as vision loss, skin diseases, etc., and the serious ones may cause cancer. For pregnant women who may cause miscarriage, elderly people with pacemakers should be especially careful. At the same time, different people or the same person have different tolerance to electromagnetic radiation at different ages.
