There are measures to reduce the radiation hazard of computers.

Computers have radiation. Everyone knows that radiation can cause disease in the end. How much harm is there?

computer-generated radiation including visible light, radio waves, low frequency waves, electrostatic and ultrasonic wave. According to the radiation condition, it is divided into free radiation and non-free radiation: free radiation comes from the picture tube; non-free radiation comes from the current and voltage of the computer display electronic parts. However, regardless of the type of radiation, under normal normal operating conditions, its strength is not enough to cause harm to the human body.

although not sufficient to produce computer radiation harmful to human health, but in the selection of computer is best to buy low radiation monitors, in addition to reducing radiation, but also can eliminate the psychological burden. In addition, there are some measures that can make the computer radiation on the human body to a minimum:

◆ Avoid prolonged continuous operation the computer, pay attention to rest. The distance between the eyes and the screen should be 40-50CM, and it is best to look at the screen with both eyes or a slight downward view.

◆ room light to fit, to avoid direct exposure to light in the screen by interference of light. The studio should be kept dry and ventilated.

◆ lying on the table to sleep when the computer shuts down to remember, not just turn off the screen. Because the head is directly facing the computer while sleeping, it is impossible to stop the radiation by turning off the screen.

◆ keep the skin clean. There is a large amount of static electricity on the surface of the computer screen. The accumulated dust can be transferred to the exposed parts of the face and hands. It will be prone to rash and pigmentation for a long time, and even cause skin lesions.

◆ attention to nutrition. Working too long before the screen, the rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized by vitamin A. Therefore, you should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement the body's vitamin A and protein. Drink more tea, tea polyphenols and other active substances in the tea will help absorb and resist radioactive substances.
