Now almost everyone has a computer - a personal computer (PC) or laptop. With the development of the Internet and social networks, people began to spend more and more time on computers. Most jobs also have a PC in their arsenal. For a modern person, a computer is a part of life. People spend more time behind them than watching TV. All this, on the one hand, makes our life easier and brings our entertainment. On the other hand, these are harmful electromagnetic radiation from a computer, noise and vibration. Few people thought about this, but still it is a fact.
Noise is created by moving elements - coolers, hard drives and a drive. Of course, in decibels these are small values, but they are constant. This effect is quite small and can be easily removed in one of three ways:
- computer repair (lubrication or replacement of components);
- work at the computer in the headphones;
- purchase of a new PC.
Noise is the easiest of all that affects a person from a computer.
Another thing is vibration. Of course, they are not radiation from a computer, but they will still be worse than noise. Vibrations are created by the same rotating elements. In fact, they can also be removed and even easier - to rearrange the system unit to the floor or away. But as a harmful factor they cannot be written off. If we consider the maximum negative effects from the computer, then still the first places are occupied by radiation from the computer and spoiling the user's vision.
The first include such computer radiation:
1. electromagnetic;
2. electrostatic;
3. X-ray.
It’s worth immediately discarding the latter, since it is relevant only for CRT monitors, i.e. containing the design of the cathode ray tube. And she, as you know, is already a relic of the past. Modern PCs are LCD or LED monitors and the system unit.
Electromagnetic radiation also relates more to the generation of CRTs, but is still present in modern monitors. This type of radiation from a computer is created exclusively by your monitor. According to danger, it takes the first place, since the person is located facing the source. Thus, the radiation is directed directly to the brain. But do not panic and throw your computer. This radiation is quite small and can not bring much harm. Some users use a special screen or film coating to protect against it. This gives them confidence and hope.
The remaining electrostatic radiation occurs in all electrical appliances. Of course, it would be better not to have anything to do with him, but there’s no getting away from him. Even commonplace sockets have a small electrostatic field. What about high voltage power lines that often run near your home?
There is also electromagnetic radiation, the effect on the human body which is still incomprehensible - not studied. For example, such emissions from elements of the system unit. Remember the epic when the panic began over mobile phones. Allegedly, they have harmful electromagnetic fields that affect the brain and potency in men. In practice, everything turned out to be not quite so. Yes, radiation exists, but its effect has not been proven. The same situation with the components of a PC or laptop.
Undoubtedly, any radiation per person is not normal. On the other hand, there is adaptation - the body's ability to adapt. Speaking of exceptions, the impact of iPad tablets has been proven to be harmless. This is what allowed Apple to get on board the aircraft of American companies in the form of assistant pilots. Is it so - time will tell. But still in airplanes, it is still forbidden to use cell phones because of the possible interference of the radiation of the device in the aircraft system.
