therefore, for us normal people, blocking the long-term radiation of blue light is the most effective way to reduce the damage.
test method of whether it is really radiation-proof: put the radiation-proof film in the position of the anti-counterfeiting watermark of 1 banknotes, and let the film cover half of the watermark. Then the blue light shines, you can see that the anti-counterfeiting watermark can't be seen where the film is covered, and the anti-counterfeiting watermark on the paper money can still be clearly seen where the film is not covered, and vice versa. As shown in figure
But actually speaking, the radiation power of the display is relatively small for the whole computer, especially when CRT monitors fade out and liquid crystal displays become popular, the radiation amount is even reduced, and it is mainly distributed on the back of the display. The most dangerous hardware of a computer's electromagnetic radiation to the human body is actually the keyboard, so I personally suggest that it is best to buy a radiation-proof keyboard film.
Question 2: How to paste the radiation-proof stickers for mobile phones, is it useful? It has a certain effect. But stick it in the right place, close to the mobile phone antenna worker. I bought a special digital mobile phone radiation detector from Taobao and did a special test. The effect is good, but sometimes it will have a certain impact on your mobile phone signal, so I'd better think about it before using it. < P > Question 3: Is the mobile phone radiation protection sticker useful? Recently, the popular mobile phone radiation protection stickers on the Internet have also appeared in the streets of Shenyang, and the price is around 5 yuan. Can a few dollars of stickers protect against radiation? Most businesses just laughed and didn't answer, and some businesses simply exposed themselves: what they sold was psychological comfort. Mobile phone anti-radiation stickers sell well. There are various mobile phone anti-radiation stickers on the Internet, and some even claim that they can prevent 99% of mobile phone radiation. The prices range from 2 yuan to 1 yuan. Yesterday, the reporter got in touch with a manufacturer in Beijing as a franchisee. The sales staff told the reporter that the products of mobile phone radiation protection stickers sold well, and the buyers were more likely to believe them with the test instruments given by the manufacturers. In addition, the so-called national inspection report can be provided. The reporter saw on a publicity webpage claiming 24K gold-plated anti-radiation sticker that the manufacturer claimed that the product had passed the anti-radiation effect test in relevant state departments and obtained the national patent certificate. It was developed by using new technology, and the effect of blocking electromagnetic wave radiation reached 99.99%. Subsequently, the staff of the relevant state departments told reporters that they had only done the corresponding tests, among which a product called "Power Quantum" in Shanghai did have such a function, and we did not issue any report, but only made a corresponding analysis on the electromagnetic radiation that quantum materials and technologies can play, demonstrating that quantum technology can only play a role in radiation defense. Many other businesses for profit did make relevant tests in advance, but did not do the test of mobile phone radiation protection stickers. As mentioned on the website,
Question 4: Is the computer anti-radiation film really useful? Many people say that computers have a lot of radiation. This news is not good news for us office workers who have been facing computers for a long time, especially pregnant office workers. So there is the rise of computer anti-radiation film, and I recently bought one. But like everyone else, I will have doubts. Can such a small film really prevent radiation? Will it really protect our eyes and even our lives? Well, let's talk about this real problem here:
Some people have done an EMC test and concluded that the computer radiation protection film has a protective effect on the screen. It can be said that no matter how hard it is, as long as the protective film does not corrode the screen, it can play a certain protective role, and it has the effects of reducing brightness, maintaining contrast and reducing color influence, but it is difficult to be convincing without certain data support in reducing radiation and absorbing ultraviolet rays;
industry experts point out that the best material to resist radiation is lead, so a good protective film against computer radiation must contain lead, so you must ask whether it contains this component when purchasing protective films. In fact, radiation is only a psychological problem for everyone, because there are laws and regulations in the country that any electrical products must produce an EMC report when they are listed, including the radiation index of computer monitors. Its index must be reduced to a level that will not affect human health before it can be sold on the market, so we don't have to care too much about this problem for some genuine products. At this time, if we buy a protective film, it will only be a psychological comfort. Of course, some lawless elements will take advantage of the loopholes and sell some inferior monitors without test reports. The radiation protection index of these monitors is beyond our control, so choosing a protective film containing lead will play its due role.
In short, nothing is absolute, but most of the computer monitors on the market are trustworthy. We can use them with confidence, and we don't need a protective film, but there are also fish in troubled waters. This tells everyone not to covet petty gain and take the underground route, which will eventually harm themselves. If you really don't want to lose them, just buy a radiation protective film and try it. Of course, I'm not saying that the protective film is useless here, but it is still useful. At least psychological comfort, money is not expensive, buy a rest assured, right
Question 5: Does the radiation protection film on the computer screen work or not? It is mainly psychological. It is unrealistic to really prevent it, but it can only be said to be weakened. You can put some plants such as cactus, or drink green tea and Guanyin lotus regularly to block a small part of computer radiation.
The most important thing is not to face the computer for a long time. Wash your face and walk around every once in a while.
question 6: is the anti-radiation film for mobile phones really useful? What's the general price? Can you really reduce the amount of radiation? I have the same answer as Building 1 ―― useless! The radiation source is far-field radiation and near-field radiation from the mobile phone antenna! Far-reaching radiation does little harm to the body, but near-field radiation is great. The electromagnetic waves generated around it are 4 to 6 times that of space electromagnetic waves, and a few inferior mobile phones are more likely to exceed 1 times! If the brain is irradiated by mobile phones for a long time, it will lead to "epilepsy" and even "brain tumor"! Light words can also cause insomnia, forgetfulness, dreaminess, dizziness, headache, irritability and other neurasthenia symptoms! This measure of anti-radiation stickers for mobile phones is unreasonable and cannot be fundamentally solved. My suggestions are as follows: 1. Try to use mobile phones as little as possible, and don't talk for a long time if you have to, or use fixed telephones as much as possible to reduce electromagnetic radiation.
2. The mobile phone signal is at the maximum power when it is connected, so it is best to put the mobile phone away from the head at the moment when the signal is connected, and it is the same when the call comes, and then answer it every five or six seconds.
3. Try to turn off the mobile phone when it is not in use. As long as the mobile phone is connected to the power supply, it will emit electromagnetic radiation, and try to keep the standby state away from the body. Now there are many mobile phones with less radiation on the market, you may change one! For example, Nokia 51, 32, 88, 761, 66, etc. are small! If you have any questions, please keep asking. I hope we can help you!
question 7: is it useful to stick a radiation protection film on the computer screen? It's no use. When is there radiation? The front of the monitor is made of thick leaded glass, with little radiation, and the back and sides are smooth. Didn't anyone tell you? The radiation of the keyboard is dozens of times that of the monitor! ! Open circuit without shielding at all.
Question 8: Can the protective screen and protective film of the computer prevent radiation? Is it useful? Just use it a little. In fact, you should stay away from playing computer games. Eating more vegetables is also good for your health. < P > Question 9: How to prevent computer radiation? Is it effective to stick a radiation protection film? 1. Apply sunscreen
Han, buy a pot of green plants next to the computer (cactus or aloe can be used)
3. Eat more radiation-proof foods (green tea, spirulina, fruits rich in vitamins)
I hope it will help you
Question 1: Is the radiation-proof film on the monitor useful? Psychological comfort ~
radiation protection dare not say, it is true that it affects the screen heat dissipation and the display quality ~
