There is radiation, not great. Copier is an electronic device, radiation is certain to have, but between the frequency of the problem, there are electromagnetic waves generated by the human damage is very small! The greatest harm to the human body of the copier is the copier in the process of copying the ozone! Because the relative space is relatively closed, ozone is not easy to dissipate! Concentration is high to a certain extent, there will be great harm to the human body! ---------------------------------------------------------------------- Hazards of radiation: people who work, study and live in an environment where radiation sources are concentrated are prone to insomnia, memory loss, weakness, low immunity, etc., and the growth of their cancer cells The growth rate of cancer cells is twenty-four times faster than that of normal people. How far is radiation from us? In our living environment, radiation is everywhere! Household appliances: TV, refrigerators, air conditioners, microwave ovens, vacuum cleaners, etc. Office equipment: cell phones, computers, copiers, electronic instruments, medical equipment, etc. Home decoration: marble, composite flooring, wallpaper, paint, etc. Surrounding environment: high-voltage lines, power substations, television (radio) signal transmission towers, etc. The natural environment: sunspots, etc. A healthy one can resist the short-lived 5,000R load, but only 700R dose is enough to make a healthy person. A healthy person can withstand a short period of 5000R load, but only 700R dose is enough to make a healthy person fatally threatened, but each person's body resistance is different, each person will have a different degree of symptoms. Generally, exposure to electromagnetic radiation can cause headaches, insomnia, irregular heart rate and other central nervous system problems. At the same time, for some people's eyes may have an impact, vision loss, skin diseases and other phenomena, heavy and may cause cancer. For pregnant women, it may lead to miscarriage, and elderly people with cardiac pacemakers should be especially careful. At the same time, different people or the same person at different ages on the tolerance of electromagnetic radiation is not the same, even in the excessive environment, does not mean that all people will get sick, so there is no need to electromagnetic radiation "grass". However, the elderly, children, pregnant women or patients with pacemakers, electromagnetic radiation-sensitive people and long-term work in an environment with excessive doses of electromagnetic radiation should take precautionary measures. ---------------------------------------------------------------------- How to prevent: With the rapid development of science and technology, a variety of scientific and technological products, household appliances into people's lives, all of which have greatly improved people's work efficiency, improved people's lives. It is hard to imagine what people's lives would be like without these energized devices. However, with the city around the high voltage, transmission towers are getting higher and higher, more and more electrical equipment at home, people feel convenient at the same time, but also in the harm. Electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. If one day, you live in the house was suddenly told in the more serious electromagnetic radiation, how would you? Can you find out which of the many household appliances have higher levels of radiation? What is electromagnetic radiation? Professionally speaking, electromagnetic radiation is the phenomenon of energy traveling through space in the form of electromagnetic waves. Almost any electrical appliance in our home generates electromagnetic radiation. For example, microwave ovens, televisions, computers, cell phones, etc! Protective clothing: including outerwear, vests, aprons, maternity clothes, etc., made of special fibers, has a better anti-electromagnetic radiation, anti-static effect. Especially families with microwave ovens, it is best to equip with protective aprons, which can effectively prevent electromagnetic radiation. For pregnant women if contact with electrical equipment, be sure to wear protective bibs or protective clothing to ensure the healthy growth of the fetus. Anti-radiation screen: with anti-radiation, anti-static, anti-glare and many other functions, also has a certain effect on the protection of eyesight. Another method is to pay attention to time and distance. The degree of damage is directly proportional to the time, that is, the longer the exposure to electromagnetic radiation, the greater the damage. And with the distance is inversely proportional to the distance, the distance is ten times bigger, the radiation is one percent of the original, the distance is one hundred times bigger, the radiation is one millionth. ---------------------------------------------------------------------- radiation best plants: cactus or cactus ball is a garden landscaping good flower varieties, although they are full of thorns, but the appearance is very beautiful ......
How much radiation does a copier emit?
At present, the copying technology more and more widely into people's work, study, life in various fields, people contact with the copier and copying products more and more opportunities, but their impact on human health has not yet attracted enough attention. According to foreign research reports, electrostatic copying machines have the following three effects on human health:
(1) At present, the most widely used is the carbon copying machine, which uses two kinds of developing powder: dry and wet. Dry developing powder is made of special grade carbon black, which has carcinogenic effects of cyclic aromatic hydrocarbons. However, because the carbon black polymer material is wrapped up after miscibility, so in the copying process, dry developer powder is rarely decomposed, very stable. Scientists have found that the developing powder contains trace nitropyrene, nitropyrene has the ability to change the normal structure of chromosomes, because it will lead to the occurrence of tumors. After technical improvement, the content of nitropyrene in dry developing powder has been greatly reduced, and its carcinogenic effect cannot be detected according to conventional methods. Wet developing powder is the carbon black dispersed in the hydrocarbon solvent, and aliphatic hydrocarbons containing 10 to 20 carbon atoms contribute to tumor growth. The hydrocarbons used are volatile due to their low boiling points, and poor ventilation can be hazardous to those with prolonged exposure.
(2) Carbonless photocopiers have a great deal of developing material *** sex, can cause skin, eyes, respiratory and nervous system and other aspects of the disease. In addition, carbonless copying can also release some potentially carcinogenic substances during the copying process.
(3) When the copier is working, there is a certain amount of ozone in the copying room due to static electricity. Ozone has a strong oxidizing effect. in November 1988, Japan's National Institute of Public **** Health Research published the results of the survey showed that in the frequent use of photocopiers, ozone concentration is sufficient to harm the human body. Through the use of some of the photocopier office and public **** library monitoring found that in the distance from the photocopier 0.5 meters, the ozone concentration of 0.12 mg / liter. These ozone is the photocopier with high-voltage components and air chemical reaction produced. Ozone has a high oxidizing effect, can be nitrogen into nitrogen oxides, the human respiratory tract has a strong *** sex. The ozone ratio is significant, slow flow, coupled with poor ventilation in the copy room due to dust control, easy to cause the copier operator to occur "copier syndrome". The main symptoms are dryness of the mouth and throat, chest tightness, cough, dizziness, headache, vision loss, etc., and in severe cases, toxic edema can occur, but also can cause symptoms of the nervous system. In addition, some of the copier operator's skin allergy symptoms may also be related to contact with the copy paper is contaminated, because the copy paper contains a number of special additive components, and in the copying process will produce confetti dust.
People engaged in long-term copying work should pay attention to strengthening labor protection, and those who are in a position to do so can install exhaust fans or exhaust ducts in the studio, so that the indoor ozone and nitrogen oxides are discharged outdoors in a timely manner. In the copier more, the workload of the room should be installed in the dust removal equipment to reduce dust. Alcohol should be used to clean the developing powder, do not use benzene solvents. The copier should be covered with something to block the glare ***. Copier operators should also increase their intake of vitamin E to protect cellular biofilms from NOx damage. In addition, there are respiratory diseases and insomnia, dizziness and pregnant women, it is best not to engage in the operation of the copier.
Copier radiation in the end how big
Very big, but the claim of carcinogenicity is more difficult to measure, can only say that there is a certain chance. However, if you are pregnant, you should try to avoid the copier.
What is the radiation from a copier? What are the effects on the human body?
The harm of the copier mainly comes from 2 aspects
1: high pressure release of ozone
2: toner leakage of pollution
Ozone has strong oxidizing properties, a small amount of ozone helps to kill bacteria in the air, which is to have a disinfecting effect, if the amount of ozone is too much will be harmful to the human body, which depends on the ventilation of the room to solve the problem! However, the ozone emissions from the copier itself is very small, as long as the ventilation is almost no harm!
The toner is mainly composed of organic matter wrapped in carbon black, which also contains trace amounts of some mercury, chromium and other metals. Copiers usually have toner leakage, which requires us to do a good job of protection, for example, when replacing the toner or cleaning the inside of the machine, try to put on a mask, pay attention to the ventilation of the room, the use of the original toner is also particularly important. The developed countries should have toner manufacturing standards much higher than those of China. Or in China, there is no standard for copier toner manufacturing, so don't be tempted to use domestic toner
The scanning lamps in copiers are usually fluorescent and halogen lamps, so they can't emit radiation that is harmful to the human body, which is nothing to worry about!
The most important thing to remember is to keep the room well ventilated. Remember!
Is there a lot of radiation from copiers?
Oh, my is my own answer, but not comprehensive, of course, can not be comprehensive! Answer the question of radiation is not pleasing to the eye, want to tell others some knowledge but no one applauded! 1, the definition of physics: the temperature is higher than -273 degrees Celsius (absolute zero) of the object have (infrared heat) radiation! Sunlight contains all the radiation, it is the protection of the atmosphere so that we are not exposed to harmful radiation and warped! Radiation according to the frequency of high and low can be simply divided into: 1, visible light (sunlight visible to the naked eye part) radiation. They are physical heat effects on the human body, that is to say, absorbing them is to produce heat on the human body! We have all been in the sun. 2, frequency lower than "visible light" invisible radiation. They and "visible light radiation" on the human body is the same physical heat effect. That is to say, the radiation of the computer and cell phone is weaker than the sunlight you are exposed to! And into the atmosphere of the sun there is a very strong ultraviolet light (frequency higher than visible light) exists, a lot of sunscreen is to prevent ultraviolet! 3, frequency higher than the "visible light" invisible radiation, they are the so-called nuclear radiation, the human body is a chemical effect, direct harm to the human body!
----- The above distinction is because "frequency x wavelength = speed of light", and the speed of light must be, so the high frequency is a short wavelength, short wavelength is strong penetration! The reason why we can go to the hospital for fluoroscopy! The x-rays emitted by medical x-ray instruments are nuclear radiation rays! And in excess, the human body will be damaged due to dna genetic information and can not correctly replicate genetic information and lead to mutation of the existence of cancer! 2, computers and other electrical appliances will not emit a frequency higher than the "visible light" radiation! But not that low frequency radiation is harmless to the human body, it is still a matter of quantity! For example, sleeping on an electric blanket, the temperature is too high, but will cause human burns! And low-frequency environments can interfere with the body's homeostasis and lead to the possibility of cancer. But a low-frequency environment, such as a high-voltage substation, cannot be caused by several computers or home appliances! The standard method of anti-radiation is only: 1, shielding radiation source, generally speaking, lead is the best shielding body, so the nuclear material is made of lead containers! 2, shielding the body to be irradiated, radiation-proof clothing (material is unknown, but estimated that there is a lead coating may be) is so! ----- shielding is wrapped tightly meaning, radiation is light waves, 300,000 kilometers per second, a little leakage, the radiation line a second can rely on the reflection filled with a certain intensity space! ----- So those who say that the use of plants, radiation maternity clothing (certainly not shielded), radiation elimination meter and so on to eliminate or prevent radiation methods are not scientific! 1, evolutionary decision of the earth's plants only suitable "visible light waves" involved in their own photosynthesis, on the useless light waves are not absorbed, reflected away. For example, green plants are green in our eyes because they do not absorb and reflect green light waves! Radiation from electrical appliances or nuclear radiation is undoubtedly invisible, and for these invisible light waves, plants that absorb them only produce physical heat! Can not be used for photosynthesis, we have never seen plants growing in the dark, right? Some materials absorb heat more strongly! But plants, especially desert plants, should be in the absorption of heat is relatively weak, because it is the desert sunlight make them become so strange shape, cactus leafless is actually afraid of the sun, afraid of water loss too fast and evolved! That is to say that the cactus is actually sunscreen anti-radiation absorption master rather than radiation absorption master, because the absorption of radiation will be converted into heat, either itself to the sun cooked, or is the loss of water! So cactus anti-radiation is really nonsense!
2, for anti-radiation maternity clothes, it is very simple, you do not tightly wrapped heh!
3, radiation eliminator! Unless it is a small black hole, how to make the elimination of radiation? Eliminate nuclear radiation, generally get up to give radiation to the soil layer shipped away to landfill it! ---------- allows copying and excerpting with credit to ----------
How big or small is the degree of radiation from a copier?
Some don't use it or don't use it,
But our family is to open a graphic store, there is no way, I have been in the whole pregnancy copying, using the computer, and even the radiation undershirt did not wear (at that time seems to have no), I'm fine, the child is very healthy.
Once came a little sister, (the stomach can not be seen,) she said to copy, escape to the outside to go, huh
The scope of the copier radiation in the 30 centimeters around the copier, as well as the computer behind the main engine is also the strongest radiation.
Relax, can not be used as little as possible, to treat the normal heart, the maternity check to be on time, take medication according to the doctor's program, can not be messed up eat, and drinking is also, of course, drive especially careful, my mother's home next to a pregnant woman, and then two months is due, and then go to Shanghai, see his husband tired, must drive, the night is really late, and the people are also very sleepy, his husband consumed him, drove an hour or so. More than an hour of car, may be too tired, not too nervous (high speed), back home, the child died, but she usually car is also driving ah. Not that the car is not good to drive, just do not be too tired. So drive also try to be careful.
It's okay, I'm also so over, because the child was born, I'm dying of pain, but I'm dizzy, I said to my mom, let my mom up and down to take a good look, is not more than a finger, less feet finger, oh, laugh people.
Pregnant moms, don't worry too much.
I hope you can help.
Computers and photocopiers are very harmful to the human body's radiation
In the photocopying of things, you'd better be far away, the working environment must be ventilated, and just off the bluff, there will be a moment of radiation, and you work with a little attention to be all right.
I wish you good health!
Copiers, printers radiation
In fact, printers, copiers are not radiation, I am doing printers, copiers maintenance, my wife was pregnant with me when I was also sitting on the printer side. They harm to the body mainly from the carbon powder because in the heating process, there will be the naked eye can not see the dust floating out of the dust is toxic inhalation of harmful to the baby, of course, that the printer is not every day work, the impact is not great, if every day to print a lot of things, then it is recommended that you do not sit next to a long time
Printer, copy machine, the printer is not radioactive.
