Is the copier radiating heavily?

Question 1: Does the copier have radiation? There is radiation, not very big. Copier is an electronic device, and the radiation is certain, but due to the frequency problem, electromagnetic waves do little harm to people! The biggest harm of copier to human body is the ozone produced by copier during copying! Because the relative space is relatively closed, ozone is not easy to dissipate! High concentration to a certain extent will do great harm to human body! -How far is the radiation from us? In our living environment, radiation is everywhere! Household appliances: TV, refrigerator, air conditioner, microwave oven, vacuum cleaner and other office equipment: mobile phones, computers, photocopiers, electronic instruments, medical devices and other home improvement: marble, composite floor, wall wallpaper, paint and other surrounding environments: high-voltage lines, substations, TV (radio) signal towers and other natural environments: a healthy sunspot can withstand a short load of 5000R, but only 700R, generally. 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. But 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! 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 shielding: it has many functions such as radiation protection, anti-static, anti-glare and so on, and it also plays a certain role in protecting eyesight. Another way is to pay attention to time and distance. The degree of injury is proportional to time, that is to say, the longer the exposure to electromagnetic radiation, the greater the injury. Is inversely proportional to the distance, the distance is ten times larger, the radiation is one percent of the original, the distance is one hundred times larger, and the radiation is one ten thousandth. - .& gt

Question 2: Are computers and photocopiers harmful to people? When you copy something, you'd better stay away. The working environment must be ventilated. Just turn off the alarm and there will be radiation for a while. Just pay attention.

I wish you the best of health!

Question 3: Why does the copier have radiation? Copying technology is more and more widely used in various fields of people's work, study and life. People have more and more opportunities to contact photocopiers and copies, but its impact on human health has not attracted enough attention. According to foreign research reports, electrostatic copiers have the following three effects on human health:

(1) At present, carbon paper is the most widely used, and dry and wet developing powder is used. The dry developing powder adopts super-grade carbon black, in which polycyclic aromatic hydrocarbons have carcinogenic effect. However, because the carbon black polymer is wrapped after mixing, the dry developing powder rarely decomposes and is very stable when copying. Scientists have found that the developing powder contains a small amount of nitropyrene, which has the ability to change the normal structure of chromosomes and will lead to tumors. After technical improvement, the content of nitropyrene in dry developing powder is greatly reduced, and its carcinogenic effect can not be detected by conventional methods. Wet developing powder disperses carbon black in hydrocarbon solvent, and aliphatic hydrocarbon containing 10 ~ 20 carbon atoms is helpful for tumor growth. Because the hydrocarbons used are volatile because of their low boiling points, poor ventilation will cause harm to long-term contact.

(2) The developing material of carbonless copier is very * *, which will cause diseases of skin, eyes, respiratory tract and nervous system. In addition, carbon-free copying will also release some substances that may cause cancer during copying.

(3) When the copier is working, there is some ozone in the copying room due to static electricity. Ozone has a strong oxidizing effect. 1988165438+10, the survey results released by Japan's National Institute of Public Health showed that the ozone concentration in places where photocopiers are frequently used is enough to cause harm to human body. Through the monitoring of some offices and public libraries that use photocopiers, it is found that the ozone concentration at a distance of 0.5m from the photocopiers is 0.12 mg/L. These ozone are produced by the chemical reaction between the parts with high voltage in the copier and the air. Ozone has a high oxidation effect, which can transform nitrogen into nitrogen oxides, and has a strong * * * effect on human respiratory tract. The heavy ozone ratio and slow flow rate, coupled with poor dust-proof and ventilation in the copy room, easily lead to copier syndrome for copier operators. The main symptoms are dry mouth and throat, chest tightness, cough, dizziness, headache and decreased vision. In severe cases, toxic edema may occur, which may also cause symptoms of mental system. In addition, the skin allergy symptoms of some copier operators may also be related to the pollution caused by contact with copy paper, because copy paper contains some special additives, which will produce paper dust during copying.

People who have been engaged in photocopying for a long time should pay attention to strengthening labor protection. Conditional can be installed in the studio exhaust fan or exhaust pipe, so that indoor ozone and nitrogen oxides can be discharged to the outside in time. Dust removal equipment should be installed in rooms with many copiers and heavy workload to reduce dust. Alcohol should be used when cleaning the developing powder, and benzene solvents should not be used. The copier should be covered with an object to block the strong light. Copier operators should also increase the intake of vitamin E to protect cell biofilm from nitrogen oxides. In addition, if you have respiratory diseases, insomnia, dizziness and pregnant women, it is best not to operate the copier.

Question 4: Does the copier radiate to human body? At present, copying technology is more and more widely used in various fields of people's work, study and life, and people have more and more opportunities to contact photocopiers and copying products, but its impact on human health has not attracted enough attention. According to foreign research reports, electrostatic copiers have the following three effects on human health:

(1) At present, carbon paper is the most widely used, and dry and wet developing powder is used. The dry developing powder adopts super-grade carbon black, in which polycyclic aromatic hydrocarbons have carcinogenic effect. However, because the carbon black polymer is wrapped after mixing, the dry developing powder rarely decomposes and is very stable when copying. Scientists have found that the developing powder contains a small amount of nitropyrene, which has the ability to change the normal structure of chromosomes and will lead to tumors. After technical improvement, the content of nitropyrene in dry developing powder is greatly reduced, and its carcinogenic effect can not be detected by conventional methods. Wet developing powder is carbon black dispersed in hydrocarbon solvent, and aliphatic hydrocarbon containing 10 ~ 20 carbon atoms is helpful for tumor growth. Because the hydrocarbons used are volatile because of their low boiling points, poor ventilation will cause harm to long-term contact.

Question 5: Do copiers and printers radiate heavily? In fact, printers and copiers do not radiate. I just fix printers and photocopiers. My wife was sitting on the printer's side when she was pregnant with my child. Their harm to the body mainly comes from toner, because invisible dust will float out during the heating process, which is toxic and harmful to the baby. Of course, the printer doesn't work every day, which has little impact. If you have to print a lot of things every day, it is recommended not to sit by for a long time.

Question 6: What radiation does the copier have? What effect does it have on the human body? The harm of photocopiers mainly comes from two aspects.

1: high pressure releases ozone.

2. Pollution caused by toner spillage

Ozone is highly oxidizing, and a small amount of ozone helps to kill bacteria in the air, that is, it has the function of disinfection. If the amount of ozone is too large, it will definitely cause harm to the human body, and indoor ventilation will be solved! However, the ozone emission of the copier itself is very small, so there is almost no harm as long as it is ventilated!

Carbon powder is mainly composed of organic carbon black, which also contains some trace mercury, chromium and other metals. Copying machines usually leak toner, which requires us to take good precautions. For example, when replacing toner or cleaning the inside of the machine, try to wear a mask and pay attention to indoor ventilation. It is also particularly important to use original toner, because the toner manufacturing standard in developed countries is much higher than that in China, or there is no standard at all in China copier toner manufacturing, so don't be greedy for cheap, use domestic toner.

The scanning lights of photocopiers are generally fluorescent lamps and halogen lamps, which cannot emit radiation harmful to human body. Don't worry! Will not affect sleep.

The most important thing is that sentence ventilation! Remember!

Question 7: What is the radiation level of the copier? Some don't or don't need it,

But our family runs a graphic shop, and I can't help it. I used a computer to copy the whole pregnancy, and I didn't even wear a radiation vest (it didn't seem to be there at that time). I'm fine, and the children are healthy.

Once, a little sister came (I still can't see her belly). She said she wanted to make a copy and fled outside, hehe.

The radiation range of the copier is 30 cm around the copier, and the back of the computer host is also the place with the strongest radiation.

Relax, use it as little as possible, treat it normally, have a checkup on time, take the medicine according to the doctor's advice, don't eat indiscriminately, and so does drinking. Of course, you should be very careful when driving. A pregnant woman next to my mother's house is due in two months, and then she goes to Shanghai to see her husband is tired and must drive. It's really late at night and people are sleepy. Her husband can't eat. He's still driving. It's not that the car is hard to drive, just don't be too tired. So try to be careful when driving.

It's okay, that's how I got here, because the baby was born, and I was in pain to death, but I told my mother in a daze to let her have a good look up and down. Is it more fingers and less toes? Hehe, that's funny.

Pregnant mother, don't worry too much.

I hope it helps you.

Question 8: Do printers and copiers have radiation? Printer: When there is current, electromagnetic waves will be generated; when there is no current, there will be no radiation; when there is current, electromagnetic waves will be generated. In particular, electronic coils and fans radiate the most, and it is best to keep a distance of more than 30 cm. And carbon dioxide is bad for your health.

For photocopiers, radiation is not the main problem, generally within the scope allowed by the state, but the exhaust gas produced by photocopiers-ozone is a problem worthy of attention. In general, the copier should be placed in a well-ventilated place or a separate place.

Question 9: How much radiation does the copier have? At present, copying technology is more and more widely used in various fields of people's work, study and life, and people have more and more opportunities to contact photocopiers and copying products, but its impact on human health has not attracted enough attention. According to foreign research reports, electrostatic copiers have the following three effects on human health:
