Question 2: Does the computer radiation eliminator really work? With the increasing frequency of people using computers, the problem of computer radiation has become one of the topics that people pay more attention to. Now there is a product on the market called computer radiation eliminator, and many people have different views on its function. Computer radiation is something that many people want to get rid of, because many people's job is to face the computer all day. With people's needs, computer radiation protectors came into being. Some people think that the effect is remarkable, while others object.
Xiao Li's job is an office clerk. As long as he goes to work, he almost faces the computer. Busy work and stressful life sometimes make Xiao Li feel very tired and sometimes feel headache. However, Xiao Li will relax completely on the rest day and his head will not hurt. Later, Xiao Li found that he would feel uncomfortable facing the computer for a long time. He looked up some information on the internet and found that the radiation of the computer is harmful to the human body. Xiao Li is afraid that her physical condition will be affected if she goes on for a long time. Xiao Li's boyfriend knew this situation and bought Xiao Li an electrical appliance called computer radiation eliminator. The instructions say that it can eliminate at least 90% of computer radiation. Xiao Li installed it on the computer the next day according to the instructions. Colleagues are very interested in this computer radiation eliminator. Everyone wants to know whether this computer radiation eliminator works well. Xiao Li used it for a while and felt it had certain effect. In fact, the principle of computer radiation eliminator is not very complicated. It uses a phase switch to connect the signal shielding wires of computer monitors, keyboards and other peripheral devices with the zero line of power supply, and then eliminates these radiations through the zero line of power supply. Many people will doubt the effect of computer radiation eliminator. Actually the answer is yes. Computer radiation eliminator can reduce radiation, but the feeling of this effect is not immediate, because radiation is invisible and intangible, and so is computer radiation. The process of radiation's influence on human body is a slow accumulation process, so radiation will not have a very obvious effect immediately, except for some sensitive people. The physical function of computer radiation eliminator has been confirmed by scientific tests. After use, the radiation is really less, and the long-term use effect can be highlighted.
Question 3: Is the computer radiation eliminator useful? It doesn't make much sense. There is radiation everywhere in life, but most of it is harmless to human body.
Question 4: Is the computer radiation large? How about Yikang computer radiation protection device? Harm of computer radiation: 1. Computer radiation pollution will affect the human body's circulatory system, immunity, reproduction and metabolic functions, which will seriously induce cancer and accelerate the proliferation of cancer cells in the human body. 2. The reproductive system is mainly affected by the decline of male quality, spontaneous abortion of pregnant women and fetal malformation. 3. The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia and decreased immune function of some women. Yikang computer radiation eliminator computer radiation eliminator eliminates computer radiation. Yikang computer radiation eliminator is connected with the computer through USB, which can eliminate more than 98% radiation released by the computer CPU, host, hard disk, mouse and keyboard. It has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, too high electromagnetic radiation pollution will also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on. Advantages and Highlights of Yikang Computer Radiation Eliminator: 1: Eliminating low frequency, intermediate frequency and high frequency radiation 2 of computers and peripheral equipment 2: USB interface connection, simple installation and use; 3: Manual control operation, normal operating rate100%; 4: Protection function of lightning protection overload equipment; 5: Anti-static human safety protection function; 6: Ozone negative ion release function, sterilization, deodorization and so on.
Question 5: Is it better to prevent computer radiation or screen? This instrument doesn't work well. The best radiation protection is lead plate or something like that. The instrument itself still emits radiation. How can we eliminate it?
Question 6: Which brand of computer radiation eliminator is better? Guangdong Hengfeng Technology Co., Ltd. is an innovative technology company. The company's predecessor, Environmental Protection Technology, was established in 2002. As one of the pioneers of domestic scientific and technological environmental protection products, Hengfeng has been committed to developing and selling professional electromagnetic protection and radiation protection products, communication equipment products and high-quality professional services, and developing together with customers and partners.
Question 7: What are the hazards of desktop computer radiation? First, computer radiation hazards
Electromagnetic radiation usually produces biological effects on the body through thermal effect, non-thermal effect and * * *. Excessive fever and long-term exposure to radiation will do harm to human body. The damage degree is directly proportional to the cumulative radiation dose and exposure time, and inversely proportional to the distance. The damage effect on different groups of people is different. Women, children and the elderly are all sensitive groups, especially the fetus.
According to experts, there are six main hazards of computer radiation.
1 may be one of the causes of childhood leukemia.
2. It can induce cancer and accelerate the proliferation of cancer cells in human body.
3, affecting the human reproductive system, mainly manifested in the decline of male quality, spontaneous abortion of pregnant women and fetal malformation.
It will lead to children's intellectual disability.
5, affecting people's cardiovascular system, manifested as palpitations, insomnia, menstrual disorder in some women, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia, decreased immune function, etc.
6. It has a bad influence on people's visual system.
Second, computer radiation protection
In fact, computer radiation is not as terrible as people say. As long as the computer is used reasonably, the harm of radiation can be minimized, and even if you are in front of the computer for a long time, you will feel tired.
1. Keeping a certain distance from the computer is one of the important measures to prevent electromagnetic radiation. Because the intensity of electromagnetic radiation decreases with the square of the distance from the radiation source. The location of the computer is very important. Try not to let the back of the screen face people, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation. Experts suggest that computer users should keep a distance of not less than 50 cm from the display screen and not less than 120 cm from the sides and back of the computer. The computer used in the office should be kept at the required distance.
It is important to reduce the time of computer contact. Because the cumulative dose of radiation is proportional to the radiation intensity and radiation time, it is necessary to reduce the computer time. Because of the need of work, it is best not to spend more than 8 hours on the computer every day, and it is best to go outdoors every hour or two.
3. Don't put metal objects indoors, so as to avoid electromagnetic wave emission again. The room should be ventilated and transparent, and plants such as fairy heads can also be placed. It is said that it has the function of calming the air and preventing radiation.
4. When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation. When using a computer, you need to adjust the brightness of the screen. Generally speaking, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa, but it should not be too dark, so as not to affect the effect because the brightness is too small, and it is easy to cause eye fatigue. You should try to buy a new computer, and generally don't use an old one. The radiation of old computers is generally severe, which is generally 1-2 times that of new computers at the same distance and similar models.
5. Some people spend a long time online without interruption. In this case, the best way is to wear protective clothing and protective cap to directly reduce the body's absorption of radiation. Pay attention to eat carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamins A, C and protein, and often drink some green tea. Green tea can not only eliminate the harm of computer radiation, but also protect and improve vision. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. Pay attention to do more outdoor sports.
6. Be aware that there is more or less radiation where there is electricity, and the amount is negligible. LCD also has radiation, but around the screen, the radiation is not as big as CRT on the desktop. You can buy a laptop or a desktop LCD computer.
Question 8: The radiation range of the computer is 20 cm. Generally speaking, as long as it is not very close, it will have no effect on the body. Just pay attention to using less wireless mouse, keyboard and headphones, which are very radioactive.
The harm of computer radiation
The radiation waves emitted by computers are often ignored. According to the international MPR radiation safety regulations, the radiation exposure within 50cm distance must be less than or equal to 25 V/m..
What is the radiation from the computer? Computer radiation: 1, keyboard1000 v/m; 2. Mouse 450 V/m; 3. Screen 218V/m; 4. Host170v/m; 5, notebook 2500 volts/meter
In addition, radiated electromagnetic waves have eight hazards to human body:
1, promoting cell canceration.
2. Hormones are abnormal
3. Severe loss of calcium ions.
4. The onset of dementia
5. Abnormal pregnancy and abnormal delivery
6. Hypertension and heart disease
7, electromagnetic wave allergy
8. The increase in the number of suicides
When using a computer, we should pay attention to the four major hazards of computer radiation as follows:
1, computer radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, seriously induce cancer and accelerate the proliferation of cancer cells in human body.
2. The reproductive system is mainly affected by the decline of male quality, spontaneous abortion of pregnant women and fetal malformation.
3. The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia and decreased immune function of some women.
4. It has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on.
How to reduce computer radiation?
As long as the brightness of the computer is set properly and the indoor light is comfortable, the LCD screen can work continuously for five or six hours, which is no problem. It's best to have a rest in the middle, wash your face with clean water, which can relieve fatigue, raise some plants that absorb radiation, and some plants that can reduce radiation: cactus plants such as Hu Jin (round prickly cactus), aloe vera and chlorophytum can reduce the radiation of the computer itself! You can make adjustments in the following ways:
1. Avoid operating the computer continuously for a long time and pay attention to rest. To maintain a most suitable posture, the distance between the eyes and the screen should be 40~50 cm, so that the eyes can look down or slightly down at the screen.
2. Maintain a good indoor working environment, such as comfortable temperature, clean air, proper negative ion concentration and ozone concentration.
3. The light in the computer room should be suitable, neither too bright nor too dark, so as to avoid the interference of light caused by direct irradiation on the fluorescent screen. The studio should be kept ventilated and dry.
4. Color filters should be used on the computer screen to reduce visual fatigue. It is best to use glass or high-quality plastic filters.
5. Install protective devices to reduce the intensity of electromagnetic radiation.
6. Pay attention to keep your skin clean. There is a lot of static electricity on the surface of computer screen, and the dust accumulated for a long time will transfer to the skin of face and hands, which is prone to macula and pigmentation, and even cause skin lesions in severe cases.
7. Pay attention to supplementary nutrition. Computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more foods such as carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers and lean meat to supplement vitamin A and protein in the human body. Drink more tea, tea polyphenols and other active substances in tea can help absorb and resist radioactive substances.
Question 9: What happens when the human body absorbs too much computer radiation? Can you remove the radiation? 1, computer radiation will affect people's nervous system, and frequent use of computers will cause headaches, insomnia, dreaminess, hair loss, memory loss and other symptoms; It can also harm the skin, eyes, endocrine system, reproductive system and nervous system, and even cause leukemia, cataract and cancer. Computer radiation is especially harmful to women and children. Women's frequent use of computers can lead to irregular menstruation, infertility, facial spots, abortion, fetal malformation and so on. Children are in the period of physical development, and frequent use of computers will lead to retinal damage, decreased vision, decreased memory, abnormal intellectual development, children.
2. The mechanism of electromagnetic radiation harm to human body is mainly thermal effect, non-thermal effect and cumulative effect.
Thermal effect: More than 70% of the human body is water, and water molecules rub against each other after being radiated by electromagnetic waves, which causes the body to heat up, thus affecting the normal work of internal organs.
Non-thermal effect: There are weak electromagnetic fields in human organs and tissues, which are stable and orderly. Once disturbed by the external electromagnetic field, the weak electromagnetic field in equilibrium will be destroyed and the human body will be damaged.
Cumulative effect: after thermal and non-thermal effects act on human body, the damage to human body has not yet had time to repair itself (commonly known as human endurance-internal resistance). If it is radiated by electromagnetic waves again, its damage degree will accumulate, and it will become permanent pathology over time, endangering health.
I'm here to introduce a product to you. Let me talk about its principle first:
When the computer leaves the factory, the real radiation is actually low, because the computer has three power sources: live wire, zero wire and ground wire. The ground wire acts like a lightning rod, which will cause redundant electricity to radiate to the earth. However, the reality is that most buildings at home and abroad now combine the ground wire and the zero wire into one or even have no ground wire at all, which leads to the generation of electric field and electromagnetic radiation from the redundant electricity of the computer. The computer radiation-proof energy-saving converter introduces the surplus electric energy generated in the computer working process into the working module through the third phase line in the product, and converts it into low-frequency current and introduces it into the power supply system. In addition, it can rectify the power supply, filter out harmonics and protect computer chips and components, thus prolonging the service life of computers. For buildings that have been connected to the ground wire, Jingfubao can still be used to eliminate electrostatic radiation and implement leakage protection (it can be detected by a digital detector, and the ground wire is below 25, and the detector cannot detect electrostatic radiation).
