Playing with cell phones quite well, which belongs to the mental retardation

Take a look at this article first you can draw good conclusions for yourself: the hazards of computer radiation The radiation waves emanating from computers are often ignored by people. According to the international MPR Ⅱ radiation safety regulations: in the 50cm distance must be less than or equal to 25V / m radiation exposure. But you know how much computer radiation? Computer radiation: 1, keyboard 1000V/m 2, mouse 450V/m 3, screen 218V/m 4, host 170V/m 5, Notebook 2500V/m In addition, the radiation of electromagnetic waves on the human body has eight major injuries: 1, cellular carcinogenicity promotion; 2, hormonal abnormalities; 3, calcium ions intense loss; 4, dementia triggered; 5, abnormal pregnancy abnormalities Production; 6, hypertension heart disease; 7, electromagnetic wave allergies; 8, the increase in suicides. The use of computers you have to pay attention to the four major hazards of computer radiation are as follows:!!!! 1, computer radiation pollution will affect the human body's circulatory system, immunity, reproduction and metabolic functions, serious will also induce cancer, and will accelerate the proliferation of cancer cells in the human body. ` 2, affecting people's reproductive system is mainly manifested in men with reduced sperm quality, pregnant women with spontaneous abortion and fetal malformation, etc. 2.}N 3, affecting people's cardiovascular system manifested in palpitations, insomnia, some women menstrual disorders, bradycardia, decreased cardiac output, sinus irregularities, leukocyte reduction, decreased immune function, etc. 5S 4, the people's visual system has a negative impact on people's eyes due to eye belongs to the human body to electromagnetic radiation sensitive organs, excessive electromagnetic radiation pollution will also have an impact on the visual system. The main manifestation of vision loss, causing cataracts, etc. Zc = AQSIQ yesterday announced the latest computer product quality national supervision and sampling results show that the electromagnetic radiation in the computer can not be ignored. AQSIQ sampling Beijing, Shanghai, Tianjin, Chongqing, Zhejiang, Hubei and other 14 provinces and municipalities of the computer products, sampling pass rate of 72%. It is understood that the results of this sampling test shows that the current domestic market computer products in computing speed, multimedia features and hardware and software support than before have improved, but the product quality level of some enterprises is not stable enough. In this sampling, four, HP, Muze and other well-known enterprises of computer products were also identified as unqualified products. It is understood that the computer product quality national inspection and sampling process found in the main quality problems is electromagnetic compatibility in the radiation nuisance, conducted nuisance indicators exceed the standard. Radiation harassment is a computer work to space emitted by an electromagnetic wave interference, this interference will affect other electrical appliances, especially high-sensitivity electrical appliances work properly; conducted harassment will affect the normal operation of other electrical appliances within the same power grid, such as the composition of the entire system of motherboards, display cards, switching power supplies, monitors, keyboards, mice, etc., if the purchase is not good enough to cause radiation harassment exceeds the standard. Sampling found that some enterprises due to insufficient understanding of the standard, parts and components import control and production line assembly quality control is not strict, the lack of the necessary testing methods, resulting in product quality is unqualified. Computer on human health hazards, from the type of radiation, mainly including computers at work and issued electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.), sound (noise), light (ultraviolet, infrared radiation, as well as visible light, etc.), and a variety of radiation "pollution". From the point of view of the source of radiation, they include CRT monitor radiation sources, chassis radiation sources, as well as speakers, printers, copiers and other peripheral equipment radiation sources. One of the CRT (cathode ray tube) monitor imaging principle, determines that it is difficult to completely eliminate harmful radiation in the process of use. Because it is working, its internal high-frequency electron gun, deflection coil, high-voltage packages and peripheral circuits, will produce such as ionizing radiation (low-energy X-rays), non-ionizing radiation (low-frequency, high-frequency radiation), electrostatic fields, optical radiation (including ultraviolet, infrared radiation and visible light, etc.) and other rays and electromagnetic waves. While the liquid crystal display is the use of physical properties of liquid crystal, its working principle is completely different from the CRT display, inherently radiation-free (negligible), environmentally friendly "health" type of display; chassis internal components, including high-frequency, power consumption of the CPU, with a large number of internal integration of transistors of the main chip of the card The various components inside the chassis, including high-frequency, power-consuming CPU, various boards with a large number of internal transistors integrated into the main chip, with high-speed DC servo motors of the CD-ROM drive, floppy drive and hard disk, a number of cooling fans and transformers inside the power supply, etc., when the work of the low-frequency electromagnetic radiation and noise interference. In addition, external speakers, copiers and other peripheral equipment radiation source is also a "source" can not be ignored. From the point of view of the degree of harm, there is no doubt that electromagnetic radiation is the most harmful. Medical experts at home and abroad research shows that long-term, excessive electromagnetic radiation will cause direct harm to the human reproductive system, nervous system and immune system, is the main cause of cardiovascular disease, diabetes, cancer mutation and cause pregnant women miscarriage, infertility, teratology and other lesions of the triggering factors, and can directly affect the minors of the body's tissues and bone development, caused by visual acuity, memory loss and decreased hematopoietic function of the liver! In addition, electromagnetic radiation can directly affect the development of minors' body tissues and bones, cause vision, memory loss and decrease in liver hematopoietic function, and lead to retinal detachment in serious cases. In addition, electromagnetic radiation is also a hidden danger to information security, the use of specialized signal receiving equipment can be received and deciphered, resulting in information leakage and unnecessary losses. Excessive electromagnetic radiation also interferes with other electronic equipment in the vicinity, affecting its normal operation and electromagnetic compatibility (EMC) problems. Therefore, electromagnetic radiation has been listed by the World Health Organization as the fourth largest source of environmental pollution after water, air, noise, and become a hazard to human health of the invisible "killer", electromagnetic radiation protection has become a priority. Protection Health Countermeasures A plan of the spear and shield As the saying goes: the devil is one foot high, the road is high. In view of the harmful effects of electromagnetic radiation from computers, relevant international and domestic professional organizations and computer manufacturers have long since begun the work of protecting against computer radiation. After years of efforts, the computer and other electronic products manufacturing, radiation, energy saving, environmental protection, ergonomics and other aspects of the development of MPR, TCO, FCC, UL and other stringent certification standards to ensure that human health is not jeopardized. At the same time, the so-called energy-saving, environmentally friendly, radiation-free "green computer" also came into being in recent years. For the harm of electromagnetic radiation of the computer, at present can take active protection and passive protection of two methods. Passive protection method, that is, in addition to improving the working environment and pay attention to the use of methods, take to frequent contact and operation of computers equipped with radiation clothing, radiation screen, radiation curtains, radiation glass and other measures to reduce or eliminate the harm of electromagnetic radiation; active protection method, is from the computer electromagnetic radiation "source" -- monitor and chassis components. -- monitor and chassis and other components to start, it will eliminate or shielding. One is to buy, that is, to buy the strength of manufacturers on the market in line with the "green computer" standard products; the second is DIY, that is, to buy through a variety of certification standards, "green" computer accessories, to create their own healthy computer. Below we will focus on how to choose to meet the radiation protection standard accessories to DIY healthy computer. CRT monitors work on the imaging principle, which determines that it is difficult to completely eliminate the harmful radiation emitted in use. In order to minimize the intensity of its harmful radiation, to protect the health of users, international authoritative organizations have launched a series of anti-electromagnetic radiation certification standards for monitors and other electronic devices, from the initial MPR Ⅰ (1987), MPR Ⅱ (1990), TCO '92 (1992) to the latest TCO '99, TCO'03 (Figure 1), strict standards have been set for radiation, energy saving, environmental protection, ergonomics and other aspects of the monitor, and only products that have followed and passed the testing of the latest relevant standards in the design, manufacturing and finished products can be called "green Only products that follow and pass the latest standards in design, manufacturing and finished products can be called "green" monitors. At present, there are nearly 20 certification standards related to monitors. Among the more famous ones are: Sweden's National Measurement and Testing Bureau's MPR II, Sweden's Professional Employees' Union (TCO) TCO series, the U.S. Environmental Protection Agency's (EPA) EnergyStar, the U.S. Federal Communications Commission's (FCC) FCC, and China's newest 3C and other certification standards. Below we focus on understanding and mastering a few common certification marks on monitors. MPR Ⅱ certification Swedish Measurement and Testing Bureau in 1987 on the electric and magnetic field radiation on human health effects and put forward one of the earliest standards - MPR Ⅰ. Based on this, it was expanded to MPRⅡ in 1990 to more strictly limit the intensity of magnetic fields generated by monitors in use, etc. It provides 21 monitor standards, including flickering, jumping, linearity, brightness, reflectivity and font size, etc., and puts forward the greatest limitations on the ultra-low-frequency (ELF) and very-low-frequency (VLF) radiations of monitors.The MPRⅡ standard has become a globally recognized and more stringent electromagnetic radiation certification mark. The MPR II standard has become a globally recognized and more stringent electromagnetic radiation detection standard. The MPR II standard has become a globally recognized and more stringent test standard for electromagnetic radiation. Most monitors on the market today comply with the MPR II specification, with the exception of a small number of inexpensive products. TCO series of certificates The Swedish Professional Employees Union (TCO) began in 1992 on the basis of MPR II, monitors and other electronic equipment in the ecology (Ecology), energy (Energy), radiation (Emissions) and ergonomics (Ergonomics) and other aspects of the higher requirements and more stringent standards, and gradually evolved into the present It has evolved into the TCO series of standards, including TCO'92/TCO'95/TCO'99/TCO'03, which are common in the world. Among them, TCO'92 is for the monitor including electromagnetic radiation, power automatic shutdown, providing power consumption data, meeting the fire prevention and electricity safety standards; TCO'95 adds the requirements of environmental protection and ergonomics on the basis of TCO'92, emphasizing the low electromagnetic radiation and low magnetic field radiation standards. TCO'95 adds requirements for environmental protection and ergonomics on the basis of TCO'92, emphasizing low electromagnetic radiation and low magnetic field radiation standards, and its coverage involves monitors, keyboards and system units, etc. TCO'99 further proposes more stringent and comprehensive standards for environmental protection and user comfort, and also puts forward specific regulations on the design of keyboards and portable machines. TCO'03, as the fourth generation of TCO certification standards, has strengthened TCO'03 over TCO'99 in terms of ecology, energy, radiation, and ergonomics of monitors, with the exception of radiation, and has become the world's most comprehensive and stringent certification standard for the new generation of TCO'03 is the world's most comprehensive and stringent certification standard for new-generation high-quality displays. FCC Certification The U.S. Federal Communications Commission (FCC) is an organization that examines electromagnetic signals and electronic equipment. It issues FCC certificates, which mainly formulate electromagnetic specifications and limit the amount of radiated noise emitted by digital devices and switching power supplies, etc. FCC certificates are divided into two classes, A and B, with more stringent technical requirements for class B. Class A products are classified as Class B, and Class B products are classified as Class B, with more stringent technical requirements. Class A products produce strong electromagnetic waves, will interfere with radio, television and other electrical appliances, so it is not suitable for home use, but can be used in the office and other places; and Class B products are said to produce relatively weak electromagnetic waves, will not interfere with microwave signals, so it can be used in the home or the office, such as personal computers or telephones belong to this type of product. CCC certification CCC is "China Compulsory Certification (ChinaCompulsoryCerlification)" abbreviation, is China's newly implemented mandatory product certification mark. At the same time, 3C certification is also the original CCEE (electrician), CCIB (import and export quarantine), EMC (electromagnetic compatibility) certification of the three in one, respectively, from the safety of electricity, electromagnetic compatibility and electromagnetic interference, stability and other comprehensive provisions of the standard. Where included in the national implementation of mandatory product certification directory of products, must be certified by the state-specified certification body to obtain the relevant certificates and affix the certification mark before the factory sales, imports and use in business activities. 3C mark has two versions: CCC (S) and CCC (S&&E). CCC (S) represents only certified by the safety standards, CCC (S&&E). (S&&E) means that the product is certified for both safety and EMC (Figure 2). Understanding and mastering the above certification standards, you will be in the purchase of "green" monitor to do "mind". In fact, when you buy you only need to "follow the prescription", specializing in picking those through the TCO '99, TCO '03, 3C and other certified products can be. Because these products through the most stringent standards such as TCO'99 testing, they are in the design, materials, manufacturing, factory, sales and other every process, each link, to try to comply with the relevant certifications contained in the standard requirements. So there is basically no need for users to understand the specific technical details of the product, as long as it passes the TCO'99 and other certifications, which means that the product's electromagnetic radiation and other hazards are minimized and can be used safely. For example, a monitor through the TCO '95, in the design to comply with ISO9241 ergonomics, IE950 safety standards, in the material to be widely used in recycling environmentally friendly non-toxic materials, in the production, manufacturing, factory process to comply with the ISO series of relevant standards as well as low electromagnetic radiation (EMI), low magnetic radiation (EMC) requirements and so on. ) requirements, and so on. It can be seen that TCO not only has very strict standards, but also its testing process and testing programs are extremely demanding. Therefore, displays that meet the TCO'95 certification standards are able to meet the requirements of "green" displays in terms of ecology, energy, radiation and ergonomics, and so on. It is certainly a wise choice for you to choose a monitor that is truly high-quality and safe. In terms of the percentage of certified monitors, radiation-free and environmentally friendly TFT LCD monitors account for a large portion of the total. In order to prevent counterfeiting, you can log on to the official inquiry website () of the TCO evaluation organization, where all manufacturers and brand names certified by TCO standards can be found. There are many monitors certified by TCO'99 and above on the market today, with major manufacturers such as Philips, LG, BenQ, acer, AOC, Patriot (aigo), NESO, and Meg launching their own excellent products. In the purchase of chassis to determine whether it has the function of anti-electromagnetic radiation, the easiest way is to check whether it has passed such as EMI, FCC, 3C and other relevant radiation standards certification. Currently on the market more representative of the typical products, there are Huaqi Patriot, Century Star, gold and field, Foxconn, Galaxy, colorful, Tt and other brands of anti-radiation chassis. When using the computer, to adjust the brightness of the screen, in general, the greater the screen brightness, the stronger the electromagnetic radiation, and vice versa, the smaller. However, it can not be adjusted too dark, so as not to affect the effect of viewing because the brightness is too small, and easy to cause eye fatigue. When operating the computer, pay attention to the screen to maintain an appropriate distance. The closer the screen, the greater the electromagnetic radiation suffered by the human body, so the better is 0.5M away from the screen. In addition, after operating the computer, the face will adsorb a lot of electromagnetic radiation particles, to wash your face with water in a timely manner, which will reduce the radiation received by more than 70%. Computer placement is very important. Try not to let the back of the screen toward someone's place, because the strongest computer radiation is the back, followed by the left and right sides, the front of the screen instead of the weakest radiation. To be able to see the word prevail, at least 50 centimeters to 75 centimeters away, which can reduce the harm of electromagnetic radiation. Attention to indoor ventilation: scientific research has confirmed that the computer screen can produce a carcinogen called brominated dibenzofuran. Therefore, it is best to install a ventilation fan in the room where the computer is placed, and if not, pay particular attention to ventilation when surfing the Internet. Care: Facial aging is most evident in the eyes, so it is particularly important to take care of the eyes. Eye Cream: It has moisturizing effect, which not only can reduce the problem of dark circles and eye bags, but also has the effect of improving wrinkles and fine lines. Eye gel: and eye cream effect is similar, just gel texture rub up more refreshing, daytime use of the skin without the burden of feeling, most of the elimination of under-eye bags, dark circles, soothing eye skin symptoms. There is a kind of tea Frequently used computer in 83% of the people feel eye fatigue, 64% often feel shoulder pain, in addition, many people appear tears, loss of appetite, sore throat, cough, chest tightness and other symptoms, and even slow action, memory loss. Computer radiation not only jeopardizes human health, but also affects the quality and efficiency of work. For people who live a stressful and busy life, the easiest way to ward off computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in vitamin A original, it is absorbed by the body, can be quickly converted into vitamin A. Vitamin A not only can synthesize retinol, but also can make the eyes in the dark light to see things more clearly, so green tea can not only eliminate the hazards of computer radiation, but also to protect and improve eyesight. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. 6:00 to 10:00 in the morning 8:00 pm 12:00 pm before this is the brain's most exciting time to protect the eyes of the Oh, every once in a while to remember to rest for ten minutes, it is best to install a computer secretary to prompt you to non-natural sources of electromagnetic radiation generally have the following four ways: (1) from the radio transmitters, such as radio, television transmitters, radar systems, and so on. (2) from the industrial frequency power system, such as high-voltage transmission lines, substations and so on. (3) From the application of electromagnetic energy industrial, medical and scientific research equipment, such as electronic instruments, medical equipment, laser photographic equipment and office automation equipment. (4) from people's daily use of household appliances, such as microwave ovens, refrigerators, air conditioners, electric blankets, televisions, video recorders, computers, cell phones and so on. Hazards of electromagnetic radiation: electromagnetic radiation, although colorless, tasteless, invisible, but can penetrate a variety of substances, including the human body, the greater the energy of electromagnetic radiation on the human body has a greater impact, such as making people appear headache, palpitations, insomnia, memory loss, white blood cell reduction, vision loss, and even affect the development of children. According to China's eugenics association statistics show that the country's annual birth of more than 200O million newborns, close to 1.2 million for the defective children, experts pointed out that the factors leading to infant defects, electromagnetic radiation is the most harmful. Other research results show that the electromagnetic waves generated by microwave ovens may induce cataracts, leading to brain abnormalities, and even reduce fertility. According to the World Health Organization, the International Commission on Non-Ionizing Radiation Protection and other authoritative departments to provide detailed data, the financial securities industry, radio and television industry, IT industry, power industry, communications industry, civil aviation, railroads, the use of high-frequency physiotherapy equipment in the medical industry, a large number of instrumentation equipment used in scientific research industry, the use of microwave electrical equipment in the industrial sector, the industry, the modernization of office equipment is quite popular, the human race with computers and mobile phones and other modern tools of life. and cell phones and other modern tools of life of human beings and other groups of people are recognized as the existence of electromagnetic radiation of high-risk groups. Visible, electromagnetic radiation called "invisible killer" is more than ever. Electromagnetic radiation protection: the hazards of electromagnetic radiation and protection has attracted great attention from countries around the world. The United Nations Conference on the Human Environment had explicitly requested governments to strengthen the prevention and control of electromagnetic radiation pollution. China has decided since January 1, 1999 onwards, on computers, monitors, printers, switching power supplies, televisions, stereos, six kinds of imported goods to implement the mandatory testing of electromagnetic compatibility, the unqualified products are rejected outside the country. The State Economic and Trade Commission and the China Consumers Association has long emphasized the need to protect against electromagnetic radiation! At present, the main measures to prevent electromagnetic radiation are generally the following. 1, distance protection According to the electromagnetic field strength in the propagation process with the increase in distance and the principle of weakening, can be taken away from the source of radiation method, so that the workplace is located in the place where the radiation intensity is minimized, to avoid working or staying close to the source of radiation right in front. Such as in the cell phone connection or dial out, the phone should be as far away from the body, in the process of calling, the human body and the cell phone antenna should also maintain a certain distance. 2, shielding protection combined with personal protection In the case that can not stay away from electronic products and electromagnetic radiation environment, people can use effective methods to limit the electromagnetic energy in the prescribed space, to stop the spread of its diffusion; on the other hand, people can also wear special protective clothing, hats and glasses, to strengthen their internal organs system, the genitourinary system and the eyes for protection. At present, the world's experts have developed a large number of electromagnetic protection products, such as protective wallpaper, protective transparent film, shielding clothing, protective glasses, "fetal protection treasure" apron, cell phone radiation screen, computer monitors protective screen, computer electromagnetic radiation shield, etc., these products can play a very good protective effect. 3, strengthen the exercise and reasonable diet Strengthen the exercise, enhance physical fitness, can improve their immune system. In addition, usually drink more green tea, eat more food rich in vitamin B, such as carrots, kelp, rape, cabbage and animal liver, etc., is also conducive to the regulation of the human body electromagnetic field disorder, increase the body's ability to resist electromagnetic radiation pollution. Admittedly, electromagnetic radiation can cause discomfort and may even produce serious harm to the human body, but it does not mean that as long as there is electromagnetic radiation, people will be in big trouble. In fact, in today's society, all of us are living in electromagnetic radiation, such as making phone calls, watching television will be subject to a certain degree of electromagnetic radiation. Therefore, we do not want to choke, talk about radiation color change, as long as the correct understanding and do a good job of adequate protection measures, electromagnetic radiation can be reduced to the minimum degree of human tolerance, people can fully enjoy the convenience of modern science and technology, but also to maintain a healthy body and a happy mood, the fish and the bear's paw at the same time, why not do it. In recent years, the study of the health effects of cell phone radiation has attracted public attention. In addition to this, cell phones will bring what health problems? ABC News announced the latest cell phone "seven deadly sins". Cell phones add which "seven deadly sins"?　　　Doctor's cell phone germs are the most New research has found that many cell phone-related health problems are not the culprits of their own cell phones, but the doctor's cell phone. A recent study published in the Annals of Clinical Microbiology in Turkey showed that of the 200 healthcare workers whose cell phones were tested, 94.5% were found to have harmful bacteria, some of which were dangerous "superbugs". Only 10% of healthcare workers clean their cell phones regularly.　　　　One of the road killers: driving a cell phone cell phone radiation on the brain is far less than the impact of driving a cell phone on the brain. Carnegie Mellon University scientists found that driving a cell phone, will lead to a reduction of 37% of the driver's attention, the risk of car accidents greatly increased.　　　Road killers two: walking and playing the phone while walking, while playing the phone or staring at the phone to surf the Internet or browse the text messages, it is most likely to ignore traffic safety, people crossing the road when "looking left and right" of the chances of a 20% decrease in the risk of traffic accidents increased by 43%.　　　Tune into the vibration, more likely to suffer from cell phone dependence "cell phone phantom hearing" is one of the most annoying by-products of the wireless era, this "cell phone is always ringing" hallucination is in fact the frequent use of cell phones lead to a psychological problem. The latest research has found that people who love to set their cell phones to vibrate are more likely to develop cell phone dependence.　　　Old texting leads to thumb syndrome Crazy texting or long time cell phone Internet access, is bound to make the thumb overload activities, resulting in thumb and finger-related tendon strain, which leads to the symptoms of thumb soreness, pain, numbness, swelling of the thumb syndrome.　　　Cell phones can also lead to allergies Some people do not use the phone for a long time, inexplicably appear skin redness, swelling, rashes and even blisters and other skin allergy symptoms. Studies have found that the main culprit for this type of contact dermatitis is certain metals, such as nickel, on cell phone shells or accessories.　　　Talking volume is too big to hurt your hearing Today, many people use their cell phones as MP3s, and there are also many people who love to turn up the volume on their cell phones. But experts say that sound over 80 decibels will hurt your ears. Normal conversation is 60 decibels, while cell phone headsets usually reach 100 decibels. In a noisy environment, people will involuntarily turn up the volume. Unbeknownst to them, hearing damage is creeping in. And then let you see how to prevent it: six types of food can be anti-radiation to dust these six types of food can be anti-radiation to dust kelp anti-radiation: kelp extract can reduce isotopes, rays on the body's immune function of the damage and inhibit apoptosis of immune cells, so that the anti-radiation effect. Millet anti-noise: in the noise environment, the human body's B vitamins consumption is very large, should eat more food rich in B vitamins, such as millet, oats, corn, etc. Black fungus anti-Cadmium: chronic cadmium poisoning can cause kidney damage in humans, or cause bone disease. Black fungus contains plant gums that can adsorb cadmium that enters the body through the digestive tract, so that it is discharged from the body. Blood tofu anti-dust: pig's blood, chicken and duck blood plasma proteins, stomach acid and digestive enzymes decomposition, can produce detoxification, intestinal substances, and invasion of the human body dust, harmful metal particles to react, into the body is not easily absorbed substances, from the digestive tract out of the body. Milk lead: Drinking milk every morning and evening can achieve the purpose of lead repellent, because milk contains protein components can be combined with the body's lead into soluble compounds, not only to prevent the body from absorbing lead, but also to promote the excretion of lead. Garlic anti-nitrosamine: long-term eating pickled, smoked products is an important risk factor for digestive malignant tumors, and garlic has a significant inhibition of nitrosamine synthesis.
