The radiation waves emitted by computers are often overlooked. 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/m2, mouse 450V/m3, screen 218V/m4, host 170V/m5, Notebook 2500V/m
Using a computer 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 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's sperm quality, pregnant women spontaneous abortion and fetal malformation, etc. 2.}N
3, affecting people's cardiovascular system is manifested in palpitations, insomnia, part of the women's menstrual period disorders, bradycardia, cardiac blood volume, sinus irregularities, leukocytes, immune function, etc. 5S
4, on people's visual system, radiation pollution will affect the human circulatory system, immunity, reproduction and metabolic function, serious cancer, and will accelerate the proliferation of cancer cells. >4, on people's visual system has an adverse effect due to the eyes belong to the human body on the sensitive organ of electromagnetic radiation, excessive electromagnetic radiation pollution will also have an impact on the visual system. The main manifestation of vision loss, causing cataracts, etc. Zc=
The placement of the computer is very important. Try not to let the back of the screen towards the place where there are people, 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 words prevail, at least 50 centimeters to 75 centimeters away, which can reduce the damage of electromagnetic radiation.
Pay 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.
