Thank you for reading this article. I hope it can help you better understand and choose a suitable computer radiation protection film.
The anti-radiation sticker must be affixed to the back of the mobile phone to effectively prevent radiation. Because mobile phone radiation mainly radiates from the backrest. In the production process of PET raw materials, a compound medium is added, and the surface of the diaphragm is coated with a radiation-proof coating (containing nanometal elements, which act as a conductor). Can play a certain role in filtering reflection. This is because most of the radiation from computers, TVs, etc. comes from electromagnetic waves from LCD screens. These waves have certain wavelengths and amplitudes. The radiation protection layer is based on the fluctuation and interference phenomena of light, which causes the difference between the front and rear surfaces of the film. Electromagnetic waves of different wavelengths interfere with each other and offset part of the radiation, achieving the effect of preventing and reducing radiation.
Currently, all computers have LCD screens, and the amount of radiation is very small; it basically does no harm to the human body, and it is safe as long as the distance is more than 30 centimeters.
Radiation-proof glasses can only weaken the radiation, but cannot completely shield it. Wearing it has a certain effect in protecting the eyes. Synthetic lenses are effective, but they are expensive, costing around a few hundred yuan.
Radiation protection is based on the "Faraday cage" principle------the outer shell of a conductor "protects" its interior from the influence of external electric fields. This This phenomenon is called electrostatic shielding.
So the radiation protection of the chassis depends on whether the detachable part and the non-detachable part form a complete conductor, that is to say, the entire shell must have good conductivity, 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, the design of the beading and tenon joints of the side panels, and the anti-EMI shrapnel design of the interface are all key factors that affect the radiation protection of the chassis. As for the diameter of the heat dissipation hole, it is generally 2-3MM and does not affect radiation protection (there are actually standards for holes).
In addition, computer radiation protection is actually to make electronic components work more stably, and has little to do with human health. Computer radiation is very small and has little impact on the human body.
As for various advertisements, they always exaggerate, confuse concepts, and mislead buyers. This is a marketing tool. Although it is despised by consumers, businesses still enjoy it because it is easier to talk about it than to make good products.

Basically, metal chassis have radiation protection function. Because electromagnetic waves cannot penetrate steel. Small holes certainly leak radiation, but they take up very little surface area of the case.
Methods to enhance radiation protection: 1. Install the side panels of the chassis, 2. There must be a grounding wire for the power socket, which is the chassis grounding, 3. Use an LCD screen, which has much less radiation than CRT, 4. Choose a high-quality chassis , high-quality power supply, good chassis with thick iron sheet and good sealing, which does not affect heat dissipation. A good power supply can reduce a lot of radiation. Basically, metal chassis have radiation protection function. Because electromagnetic waves cannot penetrate steel.

Choose a high-quality chassis , high-quality power supply, good chassis with thick iron sheet and good sealing, which does not affect heat dissipation. A good power supply can reduce a lot of radiation. Whether the radiation protection function of the chassis is excellent mainly depends on the board it uses. Most of the chassis on the market currently use galvanized steel sheets, and most ASUS chassis products use 0.8mm high-quality electrolytic galvanized steel sheets. Hazardous substances are eliminated in the electroplating and welding production processes. At the same time, it has strong adsorption to electromagnetic waves, especially low-frequency electromagnetic waves, thus achieving twice the result with half the effort in electromagnetic radiation protection. It also standardizes the use of materials in brighteners and pigment additives. Minimize radiation.
EMI bullet point radiation protection
The EMI shrapnel design on the chassis can also improve the radiation protection capability of the chassis. It is understood that good electromagnetic shielding means minimizing the shell openings and gaps, and all removable parts must be able to communicate with the chassis. To achieve this, we need to rely on the EMI shrapnel design, which can integrate the chassis frame and other components to prevent the leakage of electromagnetic waves. ASUS chassis base, front panel, top cover, rear panel edge, and even the power interface are all designed with EMI anti-electromagnetic radiation bullet points, and the bullet points are very dense, and the spacing of the bullet points is designed according to the thickness of the material to make it consistent with the The internal mechanisms are closely integrated to prevent the leakage of electromagnetic radiation to the greatest extent, making it truly radiation-proof and more environmentally friendly.
High closeness of the chassis panel
Another important aspect to prevent electromagnetic radiation is the overall design of the rack, that is, the closeness of the chassis itself, which is mainly reflected in the chassis panel , the tightness of front and rear side baffles, etc. ASUS Computer's Taipei laboratory, which has many years of R&D experience, is at the forefront of the industry in precision mold manufacturing. The combination of the seamless front panel, optical drive bay and rear panel is ASUS's meticulous effort to create a radiation-proof copper wall to prevent electromagnetic radiation from leaking out.
High density small aperture opening design of vents
In the electromagnetic wave wavelength formula c=λf, because the electromagnetic wave wavelength is related to the frequency, since the frequency is inversely proportional to the wavelength, the higher the frequency , the shorter the wavelength. When the maximum diameter of the hole is greater than 1/20 of the wavelength of the electromagnetic wave, the space electromagnetic waves in the chassis have a chance to leak out from the hole. Therefore, the shorter the wavelength, the larger the hole, and the more serious the electromagnetic radiation leakage, so in The chassis design will replace one large hole with a combination of several small holes. ASUS adopts a high-density, small-aperture opening design for vents, which not only ensures strong heat dissipation inside the chassis, but also prevents the leakage of electromagnetic radiation to the greatest extent.
Good grounding performance of the base
Utilizes its unique chassis manufacturing process and combines the chassis' galvanized steel base to make it have good grounding performance. Therefore, the electromagnetic waves generated by the electronic components inside the box can be quickly directed to the ground. From the above content, we can see that from the board to the frame design, from the EMI shrapnel to the humanized design, the ASUS chassis perfectly performs 360° radiation protection, and uses advanced technology and excellent workmanship to ensure that the ASUS chassis is fully radiation-proof. , thereby ensuring that users are protected from radiation problems and making our PC lives healthier! Radiation protection? ? So cool. Radiation. Everything with a temperature has radiation. Unless it is below absolute zero, do you think it is possible to prevent it? Electromagnetic radiation is not a big deal, just pay attention to ventilation. Does it need to make it look like the end of the world? However, it is true that the design is conducive to heat dissipation. I suggest you to understand what radiation is and you will know how to do it
is mainly attached to the screen of the monitor! If there is still some leftover, stick it to the outer shell of the main chassis. After using a computer, more than 70% of radiation ionized particles will be adsorbed on people's faces and exposed skin, causing radiation damage to the human body. Therefore, be sure to wash your face and hands after playing on the computer! Can reduce 70% of harm
When choosing computer radiation protection film, it is best to choose well-known brands, such as 3M, Belkin, Epson, etc. The radiation-proof films of these brands have been rigorously tested and can effectively reduce the impact of computer radiation on the human body.
In addition, you should also pay attention to choosing products that comply with national standards, such as radiation protection films that comply with GB/T 18801-2015 standards. In addition, according to personal needs, you can choose an anti-radiation film with anti-blue light function to further reduce damage to your eyes. The most important thing is to use the computer correctly, maintain good posture and take appropriate rest to better protect yourself from computer radiation.
has a certain effect.
Are computer radiation protection screens useful? Because most of the electromagnetic radiation from computers is between shortwave and microwave, so no screen can withstand it. However, computer radiation protection screens still have a certain effect. They can absorb at least 85% of computer radiation. It also plays a great role in protecting human health, but when purchasing, don’t be greedy and buy a few hundred yuan, otherwise it will not protect against radiation.
Today on the market, the best material to resist radiation is lead, but ordinary protective screens are so thin and contain very little lead. Computer radiation protection screens have a certain effect on radiation protection, but they do not provide 100% of the best protection. Therefore, in daily life, you should always improve your bad habits and remember to drink more water, tea, etc. In this way, the computer radiation protection screen can protect your skin from radiation damage.
The computer host is protected by a metal shell, which can shield electromagnetic radiation.
It can only be said that the harm caused by your psychological burden is greater than the so-called computer radiation
Search online for brands that many people buy and spend thousands of them Just wear it on your body to reduce the psychological burden
I did this when my wife was pregnant. I saw that she was always frowning and worried, so I simply bought a more expensive one with high-frequency circuits and radio frequency. Having been dealing with amplifiers for several years, I know that these clothes are useless for the so-called radiation protection, but I still bought it for no other reason. My wife, don’t worry
The so-called computer radiation protection is just a gimmick and feels a bit deceptive.
It is better to adjust the brightness and contrast to a suitable level, which is better for the eyes.
