computer radiation

Initially, it is better to define what “computer radiation” is. Those. what does the computer emit?

There are two sources of radiation. System unit and monitor.

1. The system unit creates only an electromagnetic field (radiation). True, there is also noise from the fans, but this topic is clear to everyone and does not require knowledge of electronics. There is definitely harm from an electromagnetic field at a high level of the field. However, the computer field creates much less than a mobile phone. Those. it is far from a microwave oven in terms of power.

2. The monitor has two main harmful factors. Beta radiation (or, more simply, a flow of electrons), which actually creates a picture on the screen, and high voltage (as in any TV, it reaches 16-20 kilovolts), which causes air ionization.

Beta radiation is propagated by the monitor in two directions - forward and backward. In old TVs and monitors, the radiation reached one or two meters from the screen (everyone remembers the recommendations not to sit closer than two or even three meters from the TV?). Those. it turned out to be a kind of powerful searchlight, shooting at us with a flurry of electrons. On the way, knocking out electrons from air molecules, turning them into positive ions, so harmful to humans. Monitors currently have very low beta levels, ie. electrons fly out of the screen for a couple of centimeters. The main radiation of the monitor is directed backwards. There, the "damage zone" extends to a meter and a half. That is what should be avoided. High voltage manages to grab electrons from air molecules, also turning the molecules into harmful positive ions. Monitor and TV manufacturers are facing increasingly stringent requirements for the use of high voltages, and this is good news.

So what to do and what to avoid? avoid extremes in the first place. If you are nervous because of every extra minute at the computer, then there will be more harm. The easiest way to deal with air ionization is to simply ventilate the premises. http://www.mamochka.org/modules.php?name=Forums&file=posting&mode=quote&p=1330

radiation exposure

Yes! The modern computer is a super wonderful thing. And its possibilities are unlimited. But is there a danger of radiation exposure (albeit in doses considered acceptable) during long-term work of people at computer screens? Answers (as always) can be several.

The first answer (beneficial to those who produce computers) is No! There is absolutely no radiation hazard. Modern computer screens are well protected. Sit at the screen for at least a day - you will be completely healthy.

The second answer - (beneficial for both those who produce computers and those who use them in their work) - Yes! A small (very small) exposure, of course. But all this is within the sanitary norms. There is no need to panic.

The third answer (beneficial for those who want to work at computer screens, know the truth, take security measures and stay healthy) - Yes! There is a risk of exposure. It really affects people's health. But there is a way out of any situation. Therefore, effective measures must be taken to protect personal safety. http://interhealth.narod.ru/inter3.html

Any electrical device affects the electromagnetic field surrounding it. It interacts with other bodies that are nearby and have even a minimal electrical charge. This rule applies even to the human body, since it is able to independently generate electrical impulses.

So the influence of a computer on a person was officially confirmed.

Mechanism of exposure to radiation

The principle of generating electrical impulses by a living organism is based on several aspects. All signals of our nervous system, heart contractions and other functions are carried out due to electrical impulses along living fibers. Any electrical appliance becomes a source of disturbance in the physical field.

Doctors say that today the total amount of permanent impact on the physical field has exceeded the possible limits. This was facilitated by electromagnetic radiation from computers, which are located in almost every home and office.

Now radiation pollution has been equated with a kind of environmental problem. The impact of the waves cannot be seen with the naked eye, which makes them especially dangerous.

Often the body does not feel the standard dosage of the effect. But if the norm exceeds the permissible mark several times, then the person feels a heat surge. Specialized equipment will help to confirm the hypothesis.

The main dangers coming from the computer

Each PC is a radio frequency and low frequency. Both types of rays have been recognized:

• carcinogens;
• enhancers of the risk of cardiovascular disease;
• hormonal failure catalysts;
• additional factors to accelerate the development of Alzheimer's disease;
• provocateurs of asthma;
• instigators of prolonged depression for no apparent reason.

Despite the stereotype that a monitor produces all harmful radiation in a PC, this is not so. All parts of the device may be hazardous. The processor poses a particularly high threat. It acts as a generator of microwave radiation.

Manufacturers of such equipment almost always care about the health of the operator. To do this, they create a special protective coating on the front side. This allows you to pay off most of the harm from the computer in relation to the main worker. But the side parts and the back cover are rarely subjected to the procedure for installing additional protection.

Fifteen years ago, technology was less suited for long-term work at home or in the office. The reason for this was dangerous monitors with a cathode ray tube in the composition. Today they are almost never seen, which pleases doctors.

But modern analogues like liquid crystal versions, although safer, are not completely harmless.

The motherboard and case also deserve attention. They cause deionization of the air. This contributes to the rapid release of harmful substances into the environment. Because of this, administrators working in server rooms often complain that the air is hard to breathe. It is especially dangerous to be in such rooms with computers without good ventilation.

The risk group included people suffering from chronic diseases associated with the broncho-pulmonary system and all people genetically predisposed to such diseases. If you work regularly in a dangerous room, you can get asthma.

Heavy air is not the only problem. No less important is the effect of the electrostatic field on dust particles suspended in a free state. They are in the air and quickly succumb to the negative influence of the PC. After a while, they become electrified and form the so-called "dust cocktail". Together, this blocks the full-fledged entry of the doses of air necessary for proper breathing into the lungs of an employee.

Some believe that in this case it is better to use tablets or smartphones. They are smaller and should generate a minimum of danger. But here, too, there are downsides. When in contact with the touch screen, the fingers are dangerously close to the wi-fi receiving antenna. The outgoing rays from it will not add health either.

The radiation from a laptop works on the same principle. It was designed as a travel companion. The portable device has become so popular with users that in the past five years it has almost ousted traditional desktop computers from the home use market.

But when using assistants so practical for the road throughout the day for a long period of time, the development of various pathologies and diseases is possible. The laptop has all the parts that a classic computer has, so you can’t hide from its radiation. Threats are added by the fact that it is usually installed closer than a stationary PC. Because of this, the distance between the monitor, the case, the processor and the human body is significantly reduced.

Worst of all, if the owner of the device has a terrible habit of putting it on its knees. So the radiation parts are in close proximity to the reproductive organs, having a negative effect on them.

PC radiation and pregnancy

Electromagnetic radiation from a computer is a particular danger to pregnant women. This applies not only to the period when a woman is already preparing to give birth, but also to the first weeks of fetal development.

The first trimester is especially important for the formation of the organs and systems of the baby. Doctors recommend reducing sitting at the computer to a minimum at least in the first half of pregnancy. This is due to the increased sensitivity of the fetus to various negative influences from the outside world. Otherwise, large-scale and regular radiation from the computer can cause:

• intrauterine damage of varying severity;
• threats of miscarriage;
• development of defects.

To protect against such dangers, gynecologists advise postponing the use of such a technique until at least the fourth month of pregnancy. Then you can afford to periodically look at e-mail and social media. But in terms of time it should be quite a bit and better - not every day.

If earlier a woman used only a laptop, then the influence from the Wi-Fi transmitter will be added to the classical radiation. Because of this, doctors insist that instead of watching movies, it is better to take a walk in good weather in the fresh air. Together, the PC can give preference to a book on a bench in a quiet square.

It will not be possible to completely abandon electrical appliances with all the desire of a modern person. Many professions are closely related to working with a computer, and it is not possible to perform it in any other way.

But it’s one thing when making money depends on a PC, and another thing is when a person wastes his health aimlessly for days on end on social networks, videos, games.

Experts remind that protection from computer radiation depends entirely on the consciousness of a particular consumer. The most important covenants here are:

• regular ventilation of the working area;
• constant walks in the fresh air;
• refusal to turn on equipment unnecessarily.

When buying new equipment, you should pay attention not only to its low cost and brand. It is important to clarify its compliance with international quality standards for safety and environmental friendliness.

Conscientious manufacturers know how to reduce the harm from a computer in an industrial environment. The accompanying installation documentation usually always contains information on a given topic.

In order to independently reduce the risks of receiving significant doses of radiation daily, you must adhere to the following recommendations:

• LCD monitor. When choosing a monitor marked “used”, you should not prioritize the low cost of options from the last century. The cathode ray tube adds a health hazard even to a person with strong immunity.
• Location. An ideal monitor position is considered to be a corner. This decision is explained by the fact that the walls will turn into a natural absorber of electromagnetic rays.
• Shutdown. To reduce the quality of exposure, it is enough to simply turn off the monitor all the time if no one is using it. For example, during an hour-long lunch break, it will be useful to turn off the monitor when leaving for the dining room.
• Special protection. Nobody canceled special protection for screens. Such an addition will be especially relevant in families with small children or nursing mothers.
• Distance. The arm's length distance is considered optimal. But this rule can only be suitable for stationary monitors with a sliding keyboard. Laptops usually stand closer due to the layout of the keyboard. This means that the distance cannot be maintained during printing. But when watching a video, the device can be moved further away.
• Correct posture. You can not put the laptop close to your face, or lean close to it.

The above tips can reduce the amount of harmful radiation.

Separately, experienced sellers of digital computer equipment have developed their own summary of recommendations. It is aimed at simultaneously prolonging the period of operation of the device and protecting health. The list includes the following items:

• place the system unit of a stationary PC away from the operator's seat;
• refuse to install a PC in close proximity to a bed;
• turn off the laptop when not working with it;
• reduce the time spent sitting in front of the monitor;
• if the work is connected with a PC, then take breaks and exercises more often.

It should be remembered that in addition to the influence of electromagnetic radiation, computers also have other disadvantages as depressors of health. Long time spent in front of the monitor impairs vision, develops problems with the musculoskeletal system. And this is not to mention the psychological consequences of immersion in the virtual world.

Most often, the eyes become the first victim of hours-long marathons in front of the PC. They are in constant tension. This is caused by a specific flickering of the monitor, which tires the organs of vision. Because of this, a person blinks less often. Refusal of the usual reflex movement may eventually result in problems with the failure of the moisture of the eye shell.

To remedy the situation, you have to wear special protective glasses, buy a special film for the monitor and use the appropriate eye drops. The latter are aimed at keeping the eye membrane moist, saving from dry eye syndrome.

Harm from different monitors

Initially, ordinary consumers who used the first generation of monitors at home were unaware of their danger. Now the harm of the cathode ray tube monitor has been proven. During its operation, the following processes take place:

• The electrons responsible for displaying the image on the screen emitted radiation. Their frequencies were
• Formation of pulsating fields of energy. At close range, they adversely affect the health of all living things.
• Prolonged action of electrical voltage. Even after such a monitor was turned off, it remained dangerous for the environment for some time.

The situation with liquid crystal monitors looks somewhat better compared to older counterparts. But this does not mean that they are completely safe. The average radiation of their working electromagnetic field is 50 Hz.

The only completely effective method of radiation prevention is only a complete rejection of the use of such equipment. But since that's not possible, just stick to basic medical advice.

Radiation from a computer causes a lot of controversial opinions. Some people argue that it is not too dangerous, while others, on the contrary, believe that it causes irreparable harm to health.

Until now, humanity has not come to a consensus.

That is why you should know what the radiation from the PC actually is, and how it affects human health.

Radiation from computer work: what is the harm?

IN modern world There is a computer in almost every home. It is used by everyone and everywhere, it is already impossible to imagine life without it. However, do not forget that this is an electrical device, and, therefore, there is electromagnetic radiation that affects a person and his condition. Many people, having spent quite a long time at the computer, begin to complain about the deterioration of their condition, pain in the head, eyes.

What happens if you use a PC for a long time? What harm is done to the body?

After some research, scientists made certain conclusions about the influence of radiation.

Conclusions:

• It is carcinogenic
• Influences the cardiac, vascular and hormonal systems,
• Can provoke the development of diseases of the brain and respiratory system,
• Reduces human immunity
• It has a negative effect on a pregnant woman and an unborn baby.
• Negatively affects the nervous system.

However, this should not be taken literally. Such consequences can develop as a result of constant long-term use of the computer.

The strongest radiation comes from the back of the monitor. Fortunately, now you almost never see monitors with a cathode ray tube. It was from them that the greatest harm to the body was.

Liquid crystal monitors are no longer so dangerous, but the waves from them also exist.

Long-term operation of the PC leads to the fact that some parts begin to heat up. As a result, harmful substances are released into the external environment. The air in such rooms is quite heavy for the respiratory system.

In addition, the air space is gradually saturated with dust particles, which are affected by the electrostatic field of the monitor. Most people who are constantly in such rooms have diseases with the respiratory system.

Particular attention should also be paid to laptops. Electromagnetic radiation is also present, so such devices also need to be used for a short time. In addition, you should not place it on your knees in front of various important organs.

Computer radiation and pregnancy

Electromagnetic radiation is very harmful to pregnant women. The fact is that at the time of the development of the baby, any intervention is unfavorable.

The influence of the electromagnetic field during this period can cause various damage to the fetus. In this case, the greatest danger is represented by early terms.

Therefore, expectant mothers should be attentive to their health and the health of their unborn baby.

By the way, radiation from a laptop is also dangerous at this time, as well as from a computer. In addition, many women continue to place this device on their knees close to the abdomen, which is far from favorable for the unborn child.

Protection from the harmful effects of the computer

Regardless of whether there is radiation from the computer, you should consider some rules for using this device in order to avoid negative consequences.

Rules:

• The distance from the back of the monitor to the back of the user must be at least one and a half meters.
• Power wires should be kept as short as possible.
• The distance to the monitor should be convenient for sight, and it should be placed in the corner of the room.
• Radiation from the system unit can be minimized by placing it at a sufficient distance from the workplace.
• In a room with a computer, it is necessary to carry out wet cleaning more often.
• When choosing a monitor, you should pay attention to the inscription Low Radiation, which indicates a low level of radiation.
• Protective screens should be used, especially for lovers of computer toys.
• If there are several PCs in the room, then they are placed around the perimeter, and the middle is left empty.

Compliance with these rules will minimize harm from the computer.

Plants in protection from computer radiation

A lot of people are convinced that the best protection against electromagnetic radiation is a cactus.

It seems like it absorbs harmful rays. However, what would then happen to the radars in Mexico, the home of this plant, if this were true?

There is only one conclusion here - not a single plant will reduce radiation. However, placing it in the workplace, you can enjoy its view. This will cheer you up, and positive emotions have a beneficial effect on the entire body.

Benefits and harms for children from the computer

Modern children spend a lot of time at the computer. Is it bad or good? Both points of view should be considered.

Harm:

• Improper arrangement of the place can cause a violation of posture, vision.
• The child's psyche may suffer.
• Computer addiction may occur when a child replaces live communication with a virtual world.
• Children under the age of five should not be allowed to use a PC at all in order to avoid developmental disorders.
• And, of course, radiation, which affects the incompletely developed children's organs.

However, using a computer can also be beneficial. So, for example, with its help you can get new information, learn about the world.

It also develops children's memory and thinking. Therefore, you should not completely exclude the computer from children's use.

However, parents should make sure that their baby does not sit at this device for a long time. In addition, it is necessary to properly organize the workplace.

Radiation from a computer can have a negative effect on the human body, like any other electrical device. However, this does not mean that you need to completely abandon the use of this device.

Just using it, you must follow the safety rules. This is especially true for parents, they need to monitor the time spent near the computer of their baby. Then the harm from it will be less than good. Many people have a computer with it, and it also does a lot of harm.

Video: the truth behind the cactus from radiation

One of the most magnificent developments of mankind is the computer.

Thanks to the ability of users to continuously communicate via PC, many people spend a huge amount of time in front of computer screens. This cannot go unnoticed, so avid computer users experience deterioration in health over time.

Involuntarily, we begin to wonder if the radiation coming from the PC affects our well-being. There are many facts for such conjectures.

According to many scientists, health problems arise in people because there is a considerable amount of electromagnetic radiation around, emanating from household appliances and communication devices.

We are the first generation of mankind, constantly under the influence of visible and invisible radiation, therefore it is impossible to determine with accuracy how such phenomena affect the human body. But scientists give some data that we will get acquainted with.

A computer is a source of low and radio frequency radiation. According to medical research, both types of radiation are carcinogenic, lead to an increased risk of cardiovascular diseases and hormonal disorders, contribute to the development of Alzheimer's disease, asthma and depression.

• All components of a computer device can be harmful. Microwave radiation is generated by the processor and then propagated into environment like an electromagnetic field, bringing a negative influence to the human EM field.
• To understand from which side of the monitor radiation brings maximum harm, you should know that its front part has a coating that protects against these waves. As for the other sides - side and back, they do not have a protective layer. When designing computer hardware, manufacturers were primarily concerned with the user in front of the PC monitor, so protecting parts other than the front wall was less of a concern.
• Thanks to modern developments cathode ray tube monitors fade into the background. It is not worth talking about their harmful effects. Today, they have been replaced by new, LCD monitors, safer, although also radioactive. It is worth noting that the parameter radiation in the operating instructions for a computer means radiation, but not radioactivity.
• During the operation of the PC, its motherboard and case heat up significantly, which leads to deionization of the air, and then the release of harmful substances into the air. That is why, in a room where computers are constantly working, the air becomes heavy. For people suffering from respiratory diseases, this factor can provoke complications.
• Despite the touch screen of innovative developments, one should not assume that radiation is completely absent, since the fingers touch the screen all the time, while being a couple of millimeters from the Wi-Fi receiver.
• Of particular note is the topic of laptops, which were invented as portable devices for use in travel conditions. If they are used for a full day without a break, it can cause many ailments.

The most important period in the life of every woman is pregnancy.

The entire period of gestation, from conception to birth, the fetus experiences various influences and perceives them extremely sensitively.

It should be understood that exposure to electromagnetic radiation can catch a baby at every stage of its development. This is especially dangerous in the first weeks of pregnancy, when there is a risk of miscarriage.

Despite the fact that the laptop is small, during pregnancy, its radiation can become no less dangerous than from a PC, given that many women continue to put it on their knees even in an interesting position.

How to protect yourself from the harmful effects of computer technology

Technological progress comes with a number of negative consequences. Nevertheless, they can be avoided, and if not, then at least minimized. What can be done to reduce the radiation from the computer?

1. Given the increased level of radiation on the back of the device, it is worth placing the PC at a distance not exceeding one and a half meters from the user's back.
2. Power wires should be kept to a minimum length.
3. Set the computer monitor at a distance convenient for viewing, and the system unit the further away from you.
4. In order to level the radiation emanating from the walls of the PC, it is better to place it in the corner of the room.
5. If you regularly wet clean the room and purchase an air ionizer, this will help provide additional protection against electromagnetic radiation.
6. Upon completion of the work, it is worth disconnecting the PC from the power supply.
7. When purchasing a monitor, pay attention to whether there is a mark on the LCD device indicating a low level of radiation.
8. Give preference to protective screens, especially if the device is used by children.
9. If it is necessary to place several computers in a room, then it is worth leaving the center of the room free, and placing the equipment along a radius.

Many office workers are sure that indoor plants are able to withstand computer radiation. Is it true if there is such a flower that will protect against the EM background coming from the PC?

The cactus has gained great popularity. These assumptions even managed to be confirmed by scientific evidence: since the cactus has needles, they act as antennas. However, given that there are no radar problems in Mexico, the home of this plant, it can be argued that this is a myth.

IMPORTANT! In reality, neither cacti nor plants are able to protect against radioactive radiation.

An indoor flowerpot is just a way to cheer up, set yourself up for work and radiate positive emotions.

Summing up, it is worth saying that you need to start protecting yourself from electromagnetic radiation from the moment you purchase computer equipment.

We all know that the space around us is filled with all kinds of energy fields and electromagnetic radiation coming from all household appliances (TV, radio, refrigerator and others).

Recently, this number of sources of electromagnetic radiation has been joined by computer .

On the one hand, it is a unique device, without which many people cannot imagine their lives and work, it is an inexhaustible source of knowledge. The word "Internet" is now known to everyone.

On the other hand, The computer is the source of many diseases. The phrases "chronic fatigue syndrome", "information stress" are also familiar to many. And that is not all.

The threat of exposure to electromagnetic field radiation on the human body has long been a scientifically proven fact. A number of diseases are associated with the influence of an electromagnetic field on the human body.

First of all, the nervous, immune, endocrine and circulatory systems suffer. This is expressed in increased fatigue, headaches, sleep disorders, allergies, anemia, reproductive dysfunction.

I think it would be appropriate to say that the Chinese called the radiation coming from the computer "dragon's teeth". Since the source of electromagnetic fields is electric current, high-current wires create powerful magnetic fields - invisible lines of force that easily penetrate everything that is in their path, including penetrating the human body.

Scientists have found that the greatest radiation from the computer comes in front and to the right of the user. This radiation exceeds the permissible limits. In the 1980s, scientists discovered that low-intensity electromagnetic fields negatively affect the ability of T-lymphocytes to destroy tumor cells. This means that such fields suppress immune system and thereby contribute to the formation of tissue tumors and blood diseases.

I will draw your special attention to the fact that in the case of exposure to weak electromagnetic fields created by the display, the reaction of the tissues can follow the repeated pulses of the field. As a result, the rhythmicity of the oscillations of the tissue elements will repeat the temporal periodicity of the field - this phenomenon is called "increase". As a result, cellular immunity and the activity of various enzymes can change, similar to what happens when tumor growth is stimulated.

Scientists have found that people working on a computer are much more likely to have children with congenital defects. By measuring the radiation emanating from the monitor, we found that it is as close as possible to the sawtooth. This has an extremely negative effect on the embryo, especially at an early stage of development. In this case, the nervous system of the unborn child suffers the most.

It has been observed that women who work on a computer are relatively more likely to have miscarriages. Doctors noted that people who have been working at a computer for more than 2 years have disorders in the work of the tail of the pancreas, this very important organ of the endocrine system.

But the radiation from the processor, which goes in all directions, is the cause of skin and allergic diseases. The situation is aggravated by the fact that the human senses do not perceive electromagnetic fields. A person does not feel this type of radiation and cannot control its level of presence. Man knows that there is radiation, but he does not know its intensity. This condition can be defined as "situational stress".

Simple and magical methods to protect people working on a computer

In order to reduce the level of harmful radiation emanating from the monitor and processor, without resorting to expensive filters and circuits, sometimes it is enough just to change the location of the computer in the room. To do this, you need to put the computer in relation to the person sitting at it, south or southwest. Since the lines of force of the background electromagnetic radiation come from the north pole and end at the south. The computer's background radiation will be tempered by natural background radiation coming from the north. As a result, an invisible barrier will appear that protects a person.

The room in which the computer is located must be living plants. It's especially good if it's pink or red pelargoniums, and plants from the family begonias. Very good plant - pike tail. Flowers must be looked after, they must be watered regularly, and, which is very important, wipe the dust from them.

But in the immediate vicinity of the computer, on the monitor or to the right of the processor, it is advisable to "settle" cactus. This unique plant will greatly help you protect your health.

It is very good if in the room in which you work, the computer will aquarium with fish. The aquarium must be round in shape. It should have odd number of fish. Among these fish must be at least one gold, red and black fish. It is desirable that the aquarium with fish falls into your field of vision when you work.

Great protective effect against harmful computer radiation, has red clay. From red clay you must mold with your own hands three balls, each with a diameter of approximately 3 cm. One ball must be placed between the monitor and the keyboard. And the other two at this time should "rest", preferably on the windowsill, so that they get sunlight, and sometimes fresh air.

Each ball should be next to the monitor for one week, and cleaned for two weeks. That is, once a week the ball at the monitor is changed to one of the two located at the window. Once every six months, clay balls must be completely replaced. Used clay balls are best left in the field.

It also has a protective property rosin. You need to take a piece of rosin, best of all in the form of a cube with a side size of at least one and a half cm or a parallelepiped measuring 2 x 4 x 1 cm and put this piece of rosin in front of the monitor. Rosin should be in front of the monitor at all times. You have to change it after a year.

Do not forget about such a simple tool as lime. Lime should be poured into a box the size of a match and placed open behind the monitor, at a distance of five centimeters from the rear wall of the monitor. Lime should be changed once every three months.
