1. The chassis can not completely shield the radiation, that is to say, a small number of radiation sources appear intentionally
Yuanli is really not clear... I suggest you check the website of radiation type.

2. The grounding wire is used to prevent static electricity, which is the same as the three plugs of general household appliances. As for shielding radiation, the transparent and plastic cases are generally not anti radiation. Most big iron brands have certain functions, but the functions are similar
if there are pregnant women, it is recommended to use a laptop, which will rece the radiation.

In the early days, chassis procts in the mechanical and electrical market all used metal primary color as the shell. Iron sheet + silver gray appearance procts are more common. Metal shell actually has many disadvantages. This kind of shell design is not so good for radiation control. However, with the increasing development of science and technology, a method has solved this dilemma, This is the blackening of the shell. The chassis procts with blackening treatment shell are more elegant and generous, and the blackening treatment is very effective for radiation control. The harm caused by radiation is great. With the blackening treatment shell, you no longer need to worry about dizziness, dreaminess and other symptoms caused by long-time use of the computer, so this design has been used by many manufacturers in the field of power supply
4. Yes, but blocked
although the chassis has radiation, its metal shell has anti radiation effect (the principle of radiation is that the current generates a magnetic field, the magnetic field generates an electric field, and the electric field generates an electric field, and then the magnetic field generates an infinite cycle. If there is a conctive object to absorb the electricity in the power plant, the radiation will be blocked)
since the personal computer, Electromagnetic radiation is more likely to be close to human beings (when operating a computer, the distance between the mouse or keyboard, the body and the screen is only about 30-60cm, so human beings are always in radiation). For centuries, human beings have suffered less from electromagnetic radiation than a person who has been using a computer for several months. When the computer is turned on, all kinds of low-frequency electromagnetic waves, including 30Hz, 60Hz, 120Hz, 1kHz, 10kHz and 10-20mhz, will be generated. Now people know the harm of computer radiation to health, so they try every means to take some protective measures to protect human health. For example, the existing video security screen and radiation protection clothing on the market.

5. The thickness of the chassis steel plate can indeed rece the radiation. The transparent side plate is still very dazzling... If you talk about the protection against computer radiation, I don't think it's necessary to consider it.
do you know what is the biggest radiation of the computer------- Your keyboard... But it's electromagnetic radiation, which is generally harmless to human body
then there are the anti radiation clothes worn by pregnant women and the anti radiation masks worn by white-collar workers. It's pure bullshit to claim that 99.9% of the anti radiation. Europe and the United States all know that this thing is deceptive...
ionizing radiation is the real harmful radiation at ordinary times, such as hospital CT, X-ray, chest X-ray, Long time high altitude flight... Do this less once, and then inlge in playing with your computer and mobile phone... Even if your computer has no chassis

6. unnecessary,
7. Radiation protection is based on the "Faraday cage" principle - the shell of the conctor plays a "protective" role in its interior, so that its interior is not affected by the external electric field, this phenomenon is called electrostatic shielding
therefore, the radiation protection of the chassis depends on whether the detachable part and the non detachable part form a complete conctor, that is to say, the whole shell must have good conctivity, and the contact between the detachable part and the non detachable part must be good and not insulated
therefore, whether the steel plate is painted or not, the design of the side panel's molding mortise and tenon, and the anti EMI shrapnel design of the interface are all the key factors affecting the anti radiation of the chassis. As for the diameter of the heat dissipation hole, generally 2-3mm does not affect the radiation protection (there is a standard for the hole)
in addition, in fact, computer radiation protection is to make electronic components work more stably, which has little to do with human health. Computer radiation is very small and has little impact on human body
as for all kinds of advertisements, they always exaggerate, confuse concepts and mislead buyers. This is a marketing method. Although they are despised by consumers, businesses still enjoy it, because it's easier to use their mouths than to make a good proct.

8. The chassis should support radiation protection, and some of them become a selling point if they do well. Of course, the radiation protection effect of cheap chassis is relatively poor. In fact, when you buy a chassis, you can take a serious look. A well shielded chassis can shield electromagnetic radiation, protect the health of users, and effectively block external radiation interference, so as to ensure that the computer is not affected by external radiation. According to the materials used, we should also pay attention to the shielding design of the details, such as setting anti radiation shrapnel at the installation position of the side panel of the chassis and the power supply position at the rear. This shrapnel will make the connection between the equipment closer and effectively prevent radiation leakage. In fact, as long as electrical appliances will have a certain amount of radiation, but will not cause too much impact on the body. In fact, the biggest radiation is the keyboard and mouse.
9. At present, most of the transparent cases are made of toughened glass, almost without radiation protection. However, the price of vacuum metal and other reinforced radiation protection cases is very high, which is not suitable for ordinary users. It is not recommended for non enthusiasts and tycoons. If you really want to use transparent cases, it is recommended that you choose the case with transparent side plate, This kind of case needs not worry about radiation protection on the non transparent side. If the transparent side adopts metal technology, the area will be smaller and the price will be much lower. The price of translucent cases such as power train, cool supreme and TT is less than 1000 yuan. If they are all transparent, the price will be more than 1000 yuan. After vacuum metal coating and electromagnetic protection, the radiation of transparent case will be smaller
10. Our computer will proce a lot of electromagnetic radiation when it works. If it is not prevented, it will cause certain harm to human body. Many consumers have noticed the harm of radiation, and when choosing computers, they specify that they should go through TCO; 99 certified display. But most people ignore the electromagnetic radiation proced by other accessories, which mainly comes from the motherboard, CPU, graphics card, sound card and other equipment. In this way, the chassis becomes the last line of defense to shield electromagnetic radiation and protect the health of users. In addition, a well shielded chassis can also effectively block the external radiation interference to ensure that the computer is not affected by external radiation. So, how to buy a well shielded chassis
shielding design of details: finally, we should pay attention to the shielding design of details. For example, anti radiation shrapnel is set at the installation position of the side panel of the chassis and the power supply position at the rear. This shrapnel will make the connection between devices closer and effectively prevent radiation leakage. Some manufacturers use steel plates with anti radiation shrapnel and anti radiation slot to shield the electromagnetic radiation more effectively, but many chassis electromagnetic radiation shielding designs often ignore this and only use ordinary steel plates as the baffle. A more intuitive way for consumers to judge whether a chassis has good radiation shielding is to check whether the chassis has passed the certification of emigb9245b, FCCB and iemcb standards. These civil standards stipulate the safety limit of radiation, and the chassis that has passed these certification will generally have detailed certificates
the above points are the problems that we should pay attention to when purchasing chassis. After meeting these requirements, beautiful appearance is the next factor that should be considered. It is our ultimate goal to purchase a cabinet with beautiful style, excellent materials, reasonable structure and safe use.
