How many times is the computer radiation bigger than the mobile phone?

When the computer is in use, the display screen will emit electromagnetic and ionizing radiation. Often working in front of the computer will make human skin aging, cause rough skin, and even cause skin inflammation and other diseases. To prevent computer radiation, we should start from the following aspects: when purchasing computers, try to buy new health-care green computers, and generally do not use old computers. The radiation dose of the old computer is large, which is generally 1-2 times that of the new computer at the same distance and similar model. When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation, and do not place miscellaneous metal objects indoors to avoid electromagnetic waves from being emitted again.

When using a computer, you need to adjust the brightness of the screen. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. But it can't be too dark, so as not to affect the viewing effect because the brightness is too small, which is easy to cause eye fatigue.

When operating the computer, pay attention to keep a proper distance from the screen. The closer you are to the screen, the greater the electromagnetic radiation the human body receives, so it is best to be 0.5M away from the screen. In addition, after operating the computer, many particles of electromagnetic radiation will be absorbed into the face. Washing your face with clean water in time will reduce radiation exposure by more than 70%.

How to avoid cell phone radiation

With the development of wireless communication technology, more and more people use mobile phones, and the related health problems brought by mobile phones have attracted more and more attention. How harmful the radiation of mobile phones is to human body, and how to minimize the harm has become the most concerned issue for mobile phone users.

When people use mobile phones, they will send radio waves to the transmitting base station, and the human body will absorb these radio waves more or less. These radio waves are the radiation of mobile phones. Generally speaking, mobile phones radiate less when they are in standby and more when they are talking. When the mobile phone number is dialed but not connected, the radiation is the largest, and the radiation amount is about three times that of standby. These radiations may change human tissues and adversely affect human health.

Don't put your mobile phone next to the pillow. Professor Zhao Yufeng, from the Indoor Environment Monitoring Committee of China Interior Decoration Association, said that mobile phone radiation is harmful to people's heads. It will cause dysfunction of people's central nervous system, causing headaches, dizziness, insomnia, dreaminess, hair loss and other symptoms, and some people will have a sense of irritation on their faces. In the United States and Japan, there have been many cases of suspected brain tumors caused by cell phone radiation. In July last year, a man with brain cancer in Maryland, USA, thought that using a mobile phone made him suffer from cancer, so he filed a lawsuit against the mobile phone manufacturer. A research report published in the European Journal of Cancer Prevention also pointed out that people who use mobile phones for a long time are 30% more likely to develop brain tumors than those who don't. People who use mobile phones for more than 10 years are more likely to develop brain tumors than those who don't use mobile phones.

Therefore, when people answer the phone, it is best to keep the phone away from their bodies and then put it in their ears to talk. In addition, try not to chat with your mobile phone, and be careful not to put your mobile phone on the pillow when you sleep. Don't hang your mobile phone on your chest. Many girls like to hang their mobile phones on their chests, but research shows that hanging them on their chests will have a certain impact on the heart and endocrine system. Even in the standby state with less radiation, the electromagnetic wave radiation around the mobile phone will cause harm to the human body. People with cardiac insufficiency and arrhythmia should pay special attention not to hang their mobile phones on their chests. Some experts believe that electromagnetic radiation will also affect endocrine function, leading to menstrual disorders in women. In addition, electromagnetic radiation will also affect normal cell metabolism, leading to the disorder of metal ions such as potassium, calcium and sodium in the body.

Mobile phones are generally equipped with shielding equipment, which can reduce the harm of radiation to human body, and shielding equipment containing heavy metals such as aluminum and lead has better protection effect. However, for the sake of beauty, women often choose compact mobile phones, and the protection function of such mobile phones may not be perfect. Therefore, before there is a small mobile phone with strong protective function, it is best for female friends not to hang it on their chests.

Hanging on the waist affects fertility. It is understood that men who often carry and use mobile phones can reduce the number of sperm by as much as 30%. Some medical experts pointed out that if the mobile phone is often hung on the waist or abdomen of the human body, the electromagnetic waves generated when it receives and sends signals will radiate to the sperm or eggs in the human body, which may affect the user's reproductive function. The British experimental report pointed out that mice irradiated by mobile phone microwave for 5 minutes will cause DNA damage; Long-term exposure of human sperm and eggs to microwave radiation from mobile phones may also cause DNA damage.

Experts advise mobile phone users to keep their mobile phones as far away from their waist and abdomen as possible, and not to hang them around their waist or put them in their coat pockets. Some men put their mobile phones in their pants pockets, which is the biggest threat to sperm, because the pants pockets are next to the testicles. When the user is in the office, at home or in the car, it is best to put the mobile phone aside. When you go out, you can put your mobile phone in your purse and stay away from your body. Connecting a mobile phone with headphones can also effectively reduce the influence of mobile phone radiation.

How to avoid being polluted by electromagnetic radiation

With the rapid development of science and technology, various scientific and technological products and household appliances have entered people's lives, which have greatly improved people's work efficiency and improved people's lives. I can't imagine what people's life would be like without these live broadcast devices. However, with more and more high-voltage electricity and transmission towers around the city, there are more and more electrical equipment at home, which makes people feel convenient and hurt at the same time. At present, electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. What would you do if one day, the house you live in was suddenly told that it was in serious electromagnetic radiation? Among the many household appliances, can you find out which ones have higher radiation? What is electromagnetic radiation? From a professional point of view, electromagnetic radiation is a phenomenon that energy propagates through space in the form of electromagnetic waves. Almost any electrical appliance in our home will produce electromagnetic radiation. Such as microwave oven, TV, computer, mobile phone and so on!

What is the difference between electromagnetic radiation and electromagnetic radiation pollution?

Actually, electromagnetic radiation and electromagnetic radiation pollution are two concepts. Any charged body has electromagnetic radiation. When the intensity of electromagnetic radiation exceeds the national standard, it will have negative effects and cause different diseases and harms to the human body. This part of radiation that exceeds the standard electromagnetic field strength is called electromagnetic radiation pollution.

What effect does the radiation of mobile phone base station have on people's health?

This is a common phenomenon. Many residential buildings in urban areas are equipped with mobile phone base stations. Some citizens are worried about whether the electromagnetic radiation generated by this equipment will cause harm to the human body. In fact, there is no need to worry about this problem. The difference between cell phone radiation and cell phone base station radiation. Generally, the electromagnetic radiation value of mobile phone is between 0.03 and 0.7, while the radiation value of mobile phone base station is 10 microwatt. The radiation value generated by the mobile phone base station is not much higher than that of the mobile phone!

In addition, the closer the electromagnetic radiation, the longer the radiation time and the deeper the damage! Moreover, the distance between the mobile phone base station installed on the roof of our general residents' home and us is a safe distance, so don't worry!

What harm will electromagnetic radiation do to human body?

Because everyone's body resistance is different, everyone will have different degrees of symptoms. Generally, being polluted by electromagnetic radiation will cause central nervous system problems such as headache, insomnia and arrhythmia. At the same time, it may affect some people's eyes, such as decreased vision, skin diseases and even cancer. For pregnant women who may cause miscarriage, the elderly who have installed pacemakers should pay special attention. At the same time, different people or the same person have different tolerance to electromagnetic radiation at different ages. Even in an environment exceeding the standard, it does not mean that everyone will get sick, so there is no need to "be a soldier" for electromagnetic radiation. However, preventive measures should be taken for the elderly, children, pregnant women or patients with pacemakers, people who are sensitive to electromagnetic radiation, and people who work in excessive electromagnetic radiation for a long time.

What items produce electromagnetic radiation?

The household appliances used in our life all have a certain amount of radiation, but the brands produced by regular manufacturers generally meet the requirements, and the electromagnetic radiation will not exceed the standard and will not bring harm.

Professionals walked into a resident's home and conducted a field test on the electromagnetic radiation in this gentleman's home!

Mr. Zhang is a civil servant. Because of the need of work, he has many electrical appliances at home, including three optical computers, two televisions and two microwave ovens. In addition, other electrical equipment running at the same time will definitely release a lot of electromagnetic radiation. He heard from his friends that electromagnetic radiation pollution may cause harm. In order to ensure the health of his family, he specially invited professionals to conduct a comprehensive test at home.

Usually computers are used the most. From here on, the tester shows that it is around 0.03, and it seems to be higher around the TV, between 0. 1-0.08. Mobile phones are often used. The test result is 0.3, which is significantly higher than the other two items.

After testing, the microwave oven at home has the highest radiation. Is the radiation in the microwave oven exceeding the standard? According to the technical staff of the Indoor Environmental Testing Center, the radiation amount is qualified within the scope stipulated by the state, so it seems that Mr. Zhang's family need not worry.

What measures should we take to prevent electromagnetic radiation?

Although electromagnetic radiation is harmful, in this electrical age, these hazards can be greatly reduced as long as some active and effective protective measures are taken.

One of the most effective preventive measures is to buy some protective equipment, which is necessary for housewives, pregnant women and people who operate computers for a long time.

Protective clothing: including coats, vests, aprons and maternity clothes. Made of special fiber, it has good anti-electromagnetic radiation and anti-static effect. Especially for families with microwave ovens, it is best to equip them with protective aprons, which can effectively prevent electromagnetic radiation. For pregnant women, if they come into contact with electrical equipment, they must wear protective Chinese-style chest covering or protective clothing to ensure the healthy growth of the fetus.

Radiation shield: it has many functions such as radiation protection, anti-static and anti-glare, and it also plays a certain role in protecting eyesight.
