Does a laptop emit a lot of radiation?

　　Experts point out that laptops have radiation, but the radiation from laptops is not large and can be ignored compared to desktop computers.

　　The main sources of computer radiation are the screen and keyboard. The radiation of notebooks mainly comes from the integration of so much hardware in such a small space. The radiation leaked by the hardware is the main source and is mainly concentrated on the keyboard. Because the laptop's LCD screen and integrated keyboard reduce radiation very well, it can be said that the radiation of laptops is the lowest among computers.

　　Does a laptop emit a lot of radiation? The radiation of a laptop is very small, but no matter how small it is, it will cause certain harm to the human body. So, how to minimize the harm of laptop radiation to the human body, the following points should be done:

　　1. Avoid operating the computer continuously for a long time and take breaks in between. To maintain the most appropriate posture, Eye The distance from the screen should be 40 to 50 centimeters, so that your eyes are looking straight or slightly downward at the fluorescent screen.

　　2. Use color filters on the computer's fluorescent screen to reduce visual fatigue. It's best to use glass or high-quality plastic filters.

　　3. Install protective devices to weaken the intensity of electromagnetic radiation.

　　4. Pay attention to keeping your skin clean. There is a large amount of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the exposed skin of the face and hands. Over time, rashes and pigmentation are prone to occur, and in severe cases, it may even cause skin disease Wait.

　　5. The light in the computer room should be appropriate, not too bright or too dark, to avoid direct light shining on the fluorescent screen and causing interference. The studio should be kept ventilated and dry.

　　6. Pay attention to nutritional supplements. When computer operators work in front of a fluorescent screen for too long, the rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized from vitamin A. Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges and milk, egg , animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. And drink more tea, the tea polyphenols and other active substances in the tea will help absorb and resist radioactive substances.

　　7. Maintain a good working environment indoors, such as comfortable temperature, clean air, appropriate anion concentration and ozone concentration, etc.
