Is radiation from a computer harmful?
A computer is one of the greatest achievements of human intelligence. The possibility of direct dialogue between users through computers and the enormous resources of a PC has led millions of people to spend more and more time in front of his screen. Over time, computer users will receive a set of certain complaints of well-being.
It makes you wonder about the effect of computer radiation on human health. There are many reasons for such thoughts. Health problems are attributed by a number of scientists to the exposure of humans to electromagnetic radiation from household microwave sources.
What is the harm of computer radiation
We are the first generation of people who live in an ocean of vast numbers of visible and invisible radiation. Therefore, there is no reliable statistics, summing up all the research scientists on this topic. So what do scholars say?
Each PC is a source of low frequency and radio frequency radiation. Health experts say:
- Both types of rays are carcinogenic;
- they increase the risk of cardiovascular diseases and hormonal disorders;
- as well as Alzheimer's disease, asthma and depression.
All parts of the computer may be harmful. The processor generates this very microwave radiation, which “with pleasure” propagates in space in the form of electromagnetic waves, often carrying misinformation, to the electromagnetic field of a person.
In order to determine the direction in which the radiation from the monitor is maximal, it should be remembered that its front end has a protective coating. But the back wall and side surfaces are not protected. Manufacturers of computer technology considered it paramount to ensure the safety of the operator sitting in front of the screen, so the view that the radiation from the monitor behind and from the sides is stronger is quite reasonable.
Monitors with a cathode ray tube, thank God, are becoming rarities of history. The harm from them was very significant. The LCD monitors that replaced them are certainly safer, but still radiation comes from them. By the way, the word radiation, indicated in the computer documentation, is translated as radiation, but not as radioactivity.
Due to the heating of the motherboard and case, air is deionized and harmful substances are released into the environment. That is why the air in the rooms, with constantly working computing equipment, is very heavy for breathing. For people with a weak respiratory system, such a factor can be disastrous, triggering asthma. It is aggravated by the influence of the electrostatic field of the computer and the monitor on airborne dust particles. Electrified, they form a “dusty cocktail” that makes breathing difficult.
The presence of the touch screen does not guarantee you the absence of radiation. After all, your fingers, making manipulations on the screen, all the time in contact with him, and a few millimeters from the wi-fi-antenna.
Special consideration should be given to the problem of radiation from a laptop, which was conceived as portable devices for working on the road. The use of these convenient and multifunctional devices during a full working day may well be the cause of all sorts of pathologies and diseases. After all, he, like a normal computer, is a source of electromagnetic radiation, and even is in close proximity to a person. Many users even carelessly place it on their knees, in close proximity to vital organs.
Computer radiation and pregnancy
The gestation period is an extremely important time in the life of a woman. From the moment of conception to the birth of a child, the growing fetus is extremely sensitive to adverse external influences. Therefore, intrauterine damage to the embryo by an electromagnetic field can occur at any stage of its development. Especially dangerous in this regard are the early stages of pregnancy, when miscarriages occur most often and malformations of an unborn baby develop. Therefore, the issue of the effect of computer radiation on pregnancy should a future mother be treated very responsibly.
Despite the compactness of the laptop radiation from it during pregnancy, no less dangerous than the same effects from a regular computer - the intensity is the same, plus the effect of a Wi-Fi transmitter. In addition, many women, even during pregnancy, do not give up the habit of keeping this portable device on your lap, that is, in the immediate vicinity of a developing baby.
Ways to protect against the harmful effects of a computer
The downside of technical progress is the dangers associated with it. How to avoid them or at least minimize? How to reduce radiation from the computer? Information about the harmful effects of its logical should be accompanied by recommendations on how to protect against its radiation.
- Since the maximum level of radiation is located in its rear panel, the distance from it to the back of another user should not be less than 1.5 m.
- It should minimize the length of the power wires.
- The monitor should be located at a convenient distance for view, and the system unit should be removed from the user as much as possible.
- To level the radiation from the walls of the monitor, place it in the corner of the room.
Wet cleaning of the room and the presence of an ionizer will serve as additional protection from electromagnetic radiation of the computer.
- Do not forget to turn off the computer at the end of work.
- Choosing a monitor, give preference to the LCD version with the inscription Low Radiation, indicating a low level of radiation.
- Do not neglect the special protective screens, which is very important if children play at the computer, who in the heat of gaming battles spend several hours at the monitor, bending low to his screen.
- When placing multiple computers in an office or classroom, they should be located around the perimeter, leaving the center of the room free.
Do plants help protect against computer radiation
Even among reputable office workers, there is an opinion that some plants protect against computer radiation.
So which flower protects against computer radiation? Preference is traditionally given here cactus. Under this myth, even the “scientific base” is summed up: the needles of the plant are assigned the role of antennas, formulas are given, and calculations are made. If this statement were a grain of truth, then in the homeland of cacti - Mexico there should be problems with the work of radars, but they are not.
The reality is that neither a cactus nor another plant will protect against computer radiation!
A flower near the computer is able to cheer up, to decorate a strict working atmosphere, to become a positive emotional component in everyday work. A "emotional placebo", is able to neutralize the detrimental effects of electromagnetic radiation.
Concluding all of the above, we conclude that the protection from the microwave radiation of a computer begins from the moment that this satellite is selected by your family in the store. And ends with a reasonable approach to its operation and dosed time spent in front of the invitingly flickering screen.
