5 thoughts on “Is the radiation of the computer room?”
Christopher
Great radiation. The more computers in the room, the more densely placed. The greater the low -frequency electromagnetic radiation in the air, the greater the damage to the human body. Radiation intensity.
The computer host, display, mouse, keyboard and related equipment around them will generate radiation, the eyes are invisible, and the hands cannot be touched. According to scientific research, the damage of low -frequency electromagnetic radiation generated by computers to the human body is hidden and accumulated; people often (long -term) use computers in ultra -intensive computer low -frequency electromagnetic radiation environments, leading to dizziness and headache. , Brain rising, tinnitus, insomnia, dry eyes, abnormal blood pressure, chest tightness, abnormal heartbeat, decreased cardiac blood volume, uneven sinus heart rate, decreased male sperm quality, some women's menstrual disorders, abortion of pregnant women, dead fetus, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, fetal malformations, and fetal malformations, fetal malformations, fetal malformations, fetal malformations, and fetal malformations, fetal malformations, and fetal malformations, fetal malformations, fetal malformations, and fetal malformations, fetal malformations, fetal malformations, and fetal deformities, Reproductive lesions, genetic lesions, cancer and other terrible diseases. In mechanisms The electromagnetic waves generated by the interactive changes of the electric field and magnetic field. The phenomenon of electromagnetic waves emit or leaked into the air is called electromagnetic radiation. Electromagnetic radiation is an invisible and invisible field. The earth where humans survive are a large magnetic field. The heat radiation and lightning on its surface can generate electromagnetic radiation. The sun and other planets continue to generate electromagnetic radiation from the outer space. Natural magnetic fields, sunlight, and household appliances around human beings all emit different radiation. Electromagnetic radiation is an external manifestation of internal atoms and molecules in the state of motion. The above reference: Baidu Encyclopedia-Electromagnetic Radiation
This radiation is quite big ~~~~~ There is no doubt. It to say that radiation protection clothes are effective, but its role is also limited, to a greater extent, it is a drama for people to deceive themselves. The fairy radiation protection is not a little effect, but it can purify the air. The reason why people think that the immortal absorption of radiation is because people think that the cactus is very strong in ultraviolet rays living on the desert and desert. In that case, it can survive, so it thinks it can prevent radiation. The electromagnetic radiation of the computer is mainly derived from various circuits in the computer, and does not produce things similar to small raw substances. Sitting in front of the computer and opening the computer, the body will start to receive electromagnetic radiation. After the computer is turned off, the electromagnetic radiation will stop immediately. There will be no "residual particles" on the face, and there is no need to wash it off. The traditional CRT display will adsorb some dust due to static electricity, but these dust itself will not produce electromagnetic radiation, and it will not cause radiation damage to the face. Traditional CRT displays may produce a small amount of ultraviolet rays. For the LCD display, the LCD screen itself is not radiated. The lamp in the back is radiation source. There is no difference between the radiation of such LCD display and the radiation of a small lamp. Need to worry. In addition, a computer is placed there, and the strength of electromagnetic radiation or electromagnetic waves launched in all directions is mainly determined by the computer itself, and the cactus cannot be shielded or adsorbed. Finally, it is also necessary to talk about that the part with high vissed light energy in electromagnetic waves can indeed cause breaks of molecular bonds. In other words, it may induce cancer. However, computer radiation with low visible light energy is far from being terrible as people imagine. Radiation needs to achieve high intensity within these frequency range to cause damage to the human body. The Chinese Academy of Metrology has performed an electromagnetic radiation test on each component of the computer. As a result, the electromagnetic radiation values of each part of the computer are less than the radiation value of the mobile phone standby. For more research on mobile phone radiation, there is no clear evidence that the scientific community has proved that mobile phone radiation will affect human health. Therefore, even if the computer is used without any protection conditions, the possibility of computer radiation affects health. Rumor cracked. This after using the computer for washing your face or using a pot of cactus next to the computer to prevent computer radiation unreliable. Washing your face can relieve the facial muscle fatigue of the computer for a long time. The fairy palm is greened to the room.
The computer host, display, mouse, keyboard, and related equipment around them will generate radiation, the eyes are invisible, and the hands cannot be touched. According to scientific research, the damage of low -frequency electromagnetic radiation generated by computers to the human body is hidden and accumulated. People often (long -term) use computers in ultra -intensive computer low -frequency electromagnetic radiation environments, leading to dizziness, headache, brain rising, rising brain, and rising brain. Tinnitus, insomnia, dry eyes, decreased vision, loss of appetite, fatigue, memory loss, some people's hair loss, leukocyte decrease, undergraduate, cataract, leukemia, brain cancer, breast cancer, vascular dilation, abnormal blood pressure, chest tightness, relief of heartbeat , Decreased cardiac blood volume, uneven sinus heart rate, reduced male sperm quality, some women's menstrual disorders, abortion of pregnant women, dead tires, fetal malformations, reproductive lesions, genetic lesions, cancer and other terrible diseases. After the computer operates the computer, many electromagnetic radiation particles will adsorb on their faces, and face rash will appear when radiation is often radiated. A person's continuous operation of the computer working for five hours, and the damage to the human body generated by the computer generated by the computer is equivalent to a day's life loss.
The more computers in the room, the more densely placed, the greater the low -frequency electromagnetic radiation in the air, the greater the damage to the human body. The radiation intensity of the northern part of the computer (screen) is greater than the radiation strength of the front (screen). Some enterprises and institutions use computer jobs. School computer classrooms and some Internet cafes are placed on the front, left and right close -ups, and the front row personnel are on the back of the back row computer display. big. Even a general "radiation protection net (board)" can only block a small part of the radiation from the front of the display. Can't solve fundamental problems. Many people mistakenly believe that as long as the "LCD Display" replaces the "ordinary" (glass) display on the computer, it can completely eliminate all radiations on the computer host, display, mouse, keyboard and surrounding related devices. In fact, it is impossible to eliminate all the radiation of each part of the computer's whole machine, but only the local radiation on the "display" is reduced by high investment, but the computer's main, mouse, keyboard and surrounding related equipment can still be eliminated. It is still a problem that hurts people.
The exaggeration, but remind everyone that work to improve efficiency, otherwise life will pass in vain. 🙂 The terminal of the computer is a monitor. Its principle is the same as the TV. When the electronic flow of the cathode ray tube hit the fluorescent screen, it can be transformed into visible light. In this process, it will generate the human body to the human body. Harm X -ray. In addition, low -frequency electromagnetic fields will be generated around VDT, which is polluted by electromagnetic waves for a long time, which can easily lead to glaucoma, blindness, leukemia, breast cancer and other diseases. According to incomplete statistics, 83 % of people who feel fatigue among common computers, 63.9 % of shoulder acid and low back pain, and 56.1 % and 54.4 % of headache and loss of appetite. Dislature, depression, arteriosclerosis psychiatry, etc.
How to minimize the harm of computer radiation to the human body. The author believes that the following points should be achieved:
1. Avoid continuously operating the computer for a long time, pay attention to the middle break. To maintain a most appropriate posture, the distance between the eyes and the screen should be 40 ~ 50 cm, so that the eyes are flat or gently watching the fluorescent screen.
2. Maintain a good working environment in the room, such as comfortable temperature, clean air, appropriate anion concentration and ozone concentration.
3. The light in the computer room should be appropriate. Do not light or dark, avoid the light directly illuminated on the fluorescent screen to generate interference light. The studio should be kept ventilated and dry.
4. The color filter should be used on the fluorescent screen of the computer to reduce visual fatigue. It is best to use glass or high -quality plastic filter.
5. Install the protective device to weaken the intensity of electromagnetic radiation.
6. Pay attention to keep the skin clean. There is a large amount of static electricity on the surface of the computer's fluorescent screen. The dust of its gathering can be transformed to the naked area of the face and the skin of the hand. Over time, it is prone to spots and pigmentation. In severe cases, it can even cause skin lesions.
7. Pay attention to nutrition. The computer operator works for too long before the fluorescent screen, and the visual purple red quality on the retina will be consumed, and the visual purple red quality is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, and milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. Drink more tea, tea polyphenols and other active substances in tea will help absorb and resist radioactive substances ================= ============================ In the X file of the computer "radiation"
Say: Jin Wuji. Computer, as a modern and high -tech product and electrical equipment, while bringing more convenience, efficiency and joy to people's lives, there are also some disadvantages that are harmful to human health.
The hidden dangers of the computer for human health. From the perspective of radiation type, it mainly includes the electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.), sound (noise), light (noise), light (noise), light (noise) during work. A variety of radiation "pollution" such as ultraviolet rays, infrared radiation, visible light, etc.).
In the root cause of the radiation, they include the radiation source of peripheral equipment such as CRT display radiation, chassis radiation source, and speakers, printers, and copies. The imaging principle of the CRT (cathode ray tube) display determines that it is difficult to completely eliminate harmful radiation during use. Because it is at work, its internal high -frequency electronic guns, deflection coils, high -voltage packs, and peripheral circuits will produce ionizing radiation (low -energy X -ray), non -electrode radiation (low -frequency, high -frequency radiation), electrostatic electric field, light radiation (light radiation, light radiation ( A variety of rays and electromagnetic waves such as ultraviolet rays, infrared radiation, visible light, etc.). The LCD display uses the physical characteristics of LCD. Its working principle is completely different from the CRT display. It is naturally "healthy" display without radiation (neglect) and environmentally friendly; The large CPU consumed, various boards with the main chip with a large number of transistors inside, the optical drives, soft drives and hard disks with high -speed DC servo motors, several heat dissipation fans, and transformers inside the power supply. Electromagnetic waves such as radiation and noise interference. In addition, the radiation source of peripheral equipment such as external speakers and copies is also a "source" that cannot be ignored.
In the degree of harm, the harm of electromagnetic radiation is undoubtedly the greatest. Research by medical experts at home and abroad shows that long -term and excessive electromagnetic radiation will cause direct damage to human reproductive systems, nervous systems, and immune systems. It is the main cause of cardiovascular disease, diabetes, and cancer. The induction factors such as tires and other lesions can directly affect the development of the body tissue and bones of minors, causing vision, memory decline and liver hematopoietic function, and severe cases can cause retina to fall off. In addition, electromagnetic radiation also causes hidden dangers for information security. Using a special signal receiving device to receive it can be resolved, resulting in information leakage and unnecessary losses. Excessive electromagnetic radiation will also interfere with other surrounding electronic equipment, affecting its normal operation and the problem of electromagnetic compatibility (EMC).
. Therefore, electromagnetic radiation has been listed by the World Health Organization as the fourth largest source of pollution after water, atmosphere, and noise, becoming invisible "killer" that endangers human health, and protecting electromagnetic radiation has become a top priority.
Protective
This Spear and Shield of Health Countermeasure A Plan
. As the saying goes: the magic is one foot high, the road is one foot high. In view of the harm of electromagnetic radiation of computers, related international, domestic professional institutions and computer manufacturers have started to protect computer radiation very early. After years of hard work, the production and manufacturing of electronic products such as computers, in terms of radiation, energy conservation, environmental protection, ergonomics, etc., MPR, TCO, FCC, UL and other strict certification standards have been formulated to ensure that human health is not subject to unwillingness. damage. At the same time, the so -called energy -saving, environmentally friendly, and radiation -free "green computers" have also emerged in recent years.
The dangers to the electromagnetic radiation of the computer can currently take two methods: active protection and passive protection. The passive protection method is in addition to improving the working environment and paying attention to the use method, it is equipped with measures such as radiation -proof uniforms, radiation -proof screens, radiation -proof curtains, radiation -proof glass and other measures for people who often contact and operate computers to reduce or eliminate electromagnetic radiation Damage; Active protection method is from the "source" of computer electromagnetic radiation -display and chassis and other components to eliminate or block it.
It is to buy, that is, buying products that are in line with the "green computer" standard launched by powerful manufacturers on the market; Your own healthy computer. Below we focus on how to choose accessories that meet the radiation protection standards to DIY health computers.
Is when using a computer, adjust the brightness of the screen. Generally speaking, the larger the screen brightness, the stronger the electromagnetic radiation, and the smaller the other. However, it cannot be tuned too dark, so as not to affect the viewing effect because the brightness is too small, and it is easy to cause eye fatigue.
Is when operating the computer, pay attention to keeping a proper distance from the screen. The closer to the screen, the greater the electromagnetic radiation of the human body, so it is better to be more than 0.5m from the screen. In addition, after operating the computer, a lot of electromagnetic radiation particles will be adsorbed on the face. Wash your face with water in time, which will reduce the radiation by more than 70%.
The more than 83 % of people who drink tea The people who use common computers feel fatigue, 64 % often feel shoulder acid and low back pain. In addition, many people have tears, loss of appetite, throat throat Symptoms such as pain, cough, chest tightness, and even slow actions and memory decline.
The computer radiation not only endangers the health of people, but also affects the quality and efficiency of work. For people who are tight and busy with life, the easiest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat a oranges every morning. Tea is rich in vitamin A, which can be quickly converted into vitamin A after being absorbed by the human body. Vitamin A can not only synthesize the purple red quality, but also make the eyes look more clear in dark light. Therefore, 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 physical functions.
The position of the computer is important. Try not to let the back of the screen towards someone, because the strongest computer radiation is the back, followed by the left and right sides, and the front of the screen is the weakest. The prevailing words are at least 50 cm to 75 cm, which can reduce the damage of electromagnetic radiation. The indoor ventilation: Scientific research confirms that the screen of the computer can produce a carcinogenic substance called bromide benzene with fucomy. Therefore, it is best to install an air -changing fan in the room where the computer is placed. If not, pay special attention to ventilation when surfing the Internet. Care: The most obvious part of the aging of the face is the eyes, so the care of the eyes is particularly important. Eye cream: There is a moisturizing effect. In addition to reducing the problems of dark circles and bags under the eyes, it also has the effect of improving wrinkles and fine lines. Eye glue: It is similar to the effect of eye cream, but the gel texture is more refreshing. There is no sense of burden on the skin during the day. Most of them are eliminated with bags under the eyes, dark circles, and soothing the symptoms of eye skin. ................................ .................................................................................................................. .................................................................................................................. ..... The radiation electromagnetic wave has eight major damage to the human body:
1, the promotion of cell cancer
2, hormonal abnormal
3, fierce loss of calcium ions
4, caused by dementia
5, abnormal pregnancy abnormal production
6, hypertension heart disease n n n n n n n n n n n n n n n n n n n n n n n n R n7, electromagnetic wave allergies
8, increased suicide
It, you should pay attention to the four major hazards of computer radiation as follows:!) 1, computer Radiation pollution can affect the human body's circulatory system, immune, reproduction and metabolic functions. It will also induce cancer and accelerate the proliferation of cancer cells in the human body. ` 2. The reproductive system that affects people is mainly manifested as the reduction of men's sperm quality, and natural abortion and fetal malformations in pregnant women. 2.} n 3, affecting people's cardiovascular systems as palpitations and insomnia. Some women's menstrual disorders, abrupt heartbeat, decreased cardiac blood volume, uneven sinus heart rate, decreased white blood cells, and decreased immune function. 5s 4. There is a adverse effect on people's visual systems. Because the eyes belong to the sensitive organ of the human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system. The main manifestations are decreased vision, causing cataract. ZC =
The latest computer product quality of the State Administration of Quality Supervision, Inspection and Quarantine of the State Inspection and Quarantine of the State Administration of Quality Supervision, Inspection and Quarantine of the State Supervision and Specification results show that electromagnetic radiation in the computer cannot be ignored.
The National Quality Inspection and Quarantine Administration of Quality Inspection and Quarantine checked computer products in 14 provinces and cities including Beijing, Shanghai, Tianjin, Chongqing, Zhejiang, and Hubei, with a sample qualification rate of 72%. It is understood that the results of this random inspection show that the current domestic market computer products have been greatly improved in terms of computing speed, multimedia functions and software and hardware support, but the quality level of some companies is not stable enough. In this spot check, computer products of well -known companies such as Sitong, Hewlett -Packard, Muze, etc. were also identified as unqualified products.
It is understood that the main quality problems found during the national inspection and random inspections of computer products are the radiation harassment and conduction harassment index in electromagnetic compatibility. Radiation harassment is an electromagnetic wave interference that emitted to space when computer work. This interference will affect the normal work of other electrical appliances, especially high -sensitivity electrical appliances; The motherboard, graphics card, switching power supply, display, keyboard, mouse, etc. The system of the system will cause the radiation harassment to exceed the standard if the purchase is not good. During the spot checks, some companies found that due to insufficient understanding of standards, component purchase control and production line assembly quality are not strict, lack of necessary detection methods, resulting in unqualified product quality
Speaking of personal feelings, the radiation of the computer room is still very large, and in addition to radiation and noise in the computer room, it is a very serious factor that damages the body. Basically, I stayed in a fainted and dizzy for one hour, and I found that the efficiency was extremely low. Which items can generate electromagnetic radiation? The appliances we use in our lives have a certain amount of radiation, but the brands produced by regular manufacturers generally meet the regulations. Electromagnetic radiation will not exceed the standard and will not bring harm. What measures should we take to prevent the infringement of electromagnetic radiation? Although electromagnetic radiation is harmful, in this electrical era, as long as some active and effective protection measures are taken, these harms can be greatly reduced. The more effective methods in preventive measures are to buy some protective utensils. For people who operate computers for housewives, pregnant women, and long -term operations, wearing radiation protection uniforms is necessary. Pai Meng (PMA) protective clothing: including coats, vests, apron, maternity clothes, etc., made of special fibers, has good anti -electromagnetic radiation and anticidering effects. For pregnant women, if you contact electrical equipment, you must put on a protective bellyband or protective to ensure the healthy growth of the fetus. The radiation -proof screen: It has various functions such as radiation protection, anti -static, anti -strong light, etc., and has certain effects on protecting vision. The people who work in the computer room can wear radiation -proof uniforms or use other radiation -proof equipment, such as: radiation -proof EMC radiation prevention card. If possible companies, they can apply for radiation -proof primer or radiation -proof surface paint. Wait.

In addition, after operating the computer, a lot of electromagnetic radiation particles will be adsorbed on the face. Wash your face with water in time, which will reduce the radiation by more than 70%.
The more than 83 % of people who drink tea
The people who use common computers feel fatigue, 64 % often feel shoulder acid and low back pain. In addition, many people have tears, loss of appetite, throat throat Symptoms such as pain, cough, chest tightness, and even slow actions and memory decline.
The computer radiation not only endangers the health of people, but also affects the quality and efficiency of work. For people who are tight and busy with life, the easiest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat a oranges every morning. Tea is rich in vitamin A, which can be quickly converted into vitamin A after being absorbed by the human body. Vitamin A can not only synthesize the purple red quality, but also make the eyes look more clear in dark light. Therefore, 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 physical functions.
The position of the computer is important. Try not to let the back of the screen towards someone, because the strongest computer radiation is the back, followed by the left and right sides, and the front of the screen is the weakest. The prevailing words are at least 50 cm to 75 cm, which can reduce the damage of electromagnetic radiation.
The indoor ventilation: Scientific research confirms that the screen of the computer can produce a carcinogenic substance called bromide benzene with fucomy. Therefore, it is best to install an air -changing fan in the room where the computer is placed. If not, pay special attention to ventilation when surfing the Internet.
Care: The most obvious part of the aging of the face is the eyes, so the care of the eyes is particularly important.
Eye cream: There is a moisturizing effect. In addition to reducing the problems of dark circles and bags under the eyes, it also has the effect of improving wrinkles and fine lines.
Eye glue: It is similar to the effect of eye cream, but the gel texture is more refreshing. There is no sense of burden on the skin during the day. Most of them are eliminated with bags under the eyes, dark circles, and soothing the symptoms of eye skin.

The radiation electromagnetic wave has eight major damage to the human body:
1, the promotion of cell cancer
2, hormonal abnormal
3, fierce loss of calcium ions
4, caused by dementia
5, abnormal pregnancy abnormal production
6, hypertension heart disease

8, increased suicide
It, you should pay attention to the four major hazards of computer radiation as follows:!)
1, computer Radiation pollution can affect the human body's circulatory system, immune, reproduction and metabolic functions. It will also induce cancer and accelerate the proliferation of cancer cells in the human body. `
2. The reproductive system that affects people is mainly manifested as the reduction of men's sperm quality, and natural abortion and fetal malformations in pregnant women. 2.} n
3, affecting people's cardiovascular systems as palpitations and insomnia. Some women's menstrual disorders, abrupt heartbeat, decreased cardiac blood volume, uneven sinus heart rate, decreased white blood cells, and decreased immune function. 5s
4. There is a adverse effect on people's visual systems. Because the eyes belong to the sensitive organ of the human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system. The main manifestations are decreased vision, causing cataract. ZC =
The latest computer product quality of the State Administration of Quality Supervision, Inspection and Quarantine of the State Inspection and Quarantine of the State Administration of Quality Supervision, Inspection and Quarantine of the State Supervision and Specification results show that electromagnetic radiation in the computer cannot be ignored.
The National Quality Inspection and Quarantine Administration of Quality Inspection and Quarantine checked computer products in 14 provinces and cities including Beijing, Shanghai, Tianjin, Chongqing, Zhejiang, and Hubei, with a sample qualification rate of 72%. It is understood that the results of this random inspection show that the current domestic market computer products have been greatly improved in terms of computing speed, multimedia functions and software and hardware support, but the quality level of some companies is not stable enough. In this spot check, computer products of well -known companies such as Sitong, Hewlett -Packard, Muze, etc. were also identified as unqualified products.
It is understood that the main quality problems found during the national inspection and random inspections of computer products are the radiation harassment and conduction harassment index in electromagnetic compatibility. Radiation harassment is an electromagnetic wave interference that emitted to space when computer work. This interference will affect the normal work of other electrical appliances, especially high -sensitivity electrical appliances; The motherboard, graphics card, switching power supply, display, keyboard, mouse, etc. The system of the system will cause the radiation harassment to exceed the standard if the purchase is not good. During the spot checks, some companies found that due to insufficient understanding of standards, component purchase control and production line assembly quality are not strict, lack of necessary detection methods, resulting in unqualified product quality
Speaking of personal feelings, the radiation of the computer room is still very large, and in addition to radiation and noise in the computer room, it is a very serious factor that damages the body. Basically, I stayed in a fainted and dizzy for one hour, and I found that the efficiency was extremely low.
Which items can generate electromagnetic radiation?
The appliances we use in our lives have a certain amount of radiation, but the brands produced by regular manufacturers generally meet the regulations. Electromagnetic radiation will not exceed the standard and will not bring harm.
What measures should we take to prevent the infringement of electromagnetic radiation?
Although electromagnetic radiation is harmful, in this electrical era, as long as some active and effective protection measures are taken, these harms can be greatly reduced.
The more effective methods in preventive measures are to buy some protective utensils. For people who operate computers for housewives, pregnant women, and long -term operations, wearing radiation protection uniforms is necessary.
Pai Meng (PMA) protective clothing: including coats, vests, apron, maternity clothes, etc., made of special fibers, has good anti -electromagnetic radiation and anticidering effects. For pregnant women, if you contact electrical equipment, you must put on a protective bellyband or protective to ensure the healthy growth of the fetus.
The radiation -proof screen: It has various functions such as radiation protection, anti -static, anti -strong light, etc., and has certain effects on protecting vision.
The people who work in the computer room can wear radiation -proof uniforms or use other radiation -proof equipment, such as: radiation -proof EMC radiation prevention card. If possible companies, they can apply for radiation -proof primer or radiation -proof surface paint. Wait.
There are generally, but what is the opportunity.
