Different from common electronic products, photocopiers can also pollute the air, mainly eliminating ozone when working. One of the sources of ozone is the gas formed by heating polyester resin, the main component of carbon powder, which is similar to the gas emitted by automobile exhaust. Does that mean it's not safe for you to walk on the road? That was not the case. Automobile exhaust emission standards are strictly controlled, and the air pollution caused by exhaust emission can be reduced by upgrading the gasoline label.
Going back to the copier, it's also exhausting, isn't it harmful to the body? Yes, but very few. After all, all deadly gases are strictly tested to ensure the quality of toner and the emission of waste gas.
From 1996, the World Health Organization (WHO) organized more than 60 countries and international organizations to carry out the global "International Electromagnetic Field Plan", which lasted for 10 years, and conducted a comprehensive health risk assessment of electromagnetic radiation in life, including childhood cancer, adult cancer, depression, suicide, cardiovascular disease, infertility, developmental disorder, immune system variation, and so on. Finally, the WHO expert working group concluded that the electromagnetic radiation that the public usually encounters has no actual health problems.
"If the magnetic field intensity is controlled within the prescribed range, the effect of electromagnetic radiation on the human body is beneficial. For example, some physiotherapy machines sold in the market use the warm effect of electromagnetic radiation to achieve the purpose of eliminating inflammation and treatment. The key is to control radiation within the scope of national safety standards.
It is not ruled out that there may be some inferior mobile phones in the market whose radiation will exceed this standard, so the public should still have the awareness of radiation protection. A medical expert from the Third Military Medical University said, "The radiation of mobile phones mainly comes from antennas, including external antennas and built-in antennas. The intensity of radiation is inversely proportional to the distance between the mobile phone and the human body. Using headphones or hands-free functions can reduce the harm of radiation to the human body. "
It should be noted that you should not use the copier for a long time in a narrow and closed space. Closed use for a long time will lead to poor ozone discharge and cause dizziness, nausea and other symptoms. Therefore, it is very important to keep office ventilation and air circulation.
There is also a saying that you should not be too close to the copier, and some people even deliberately apply for a change of location. Actually, it's totally unnecessary. As long as your body keeps a certain distance from the exhaust port of the copier, it won't have much influence on all aspects of people, so you don't have to worry about sleep problems. Just as air conditioners can't be blown at the head for a long time, keeping a good mood and working hard are the things that should be considered.

Influence of electromagnetic radiation
With the rapid development of science and technology, various scientific and technological products and household appliances have entered people's lives, greatly improving people's work efficiency and improving people's lives. However, with the increasing number of high-voltage electricity and transmission towers around the city, there are more and more electrical equipment at home, which makes people feel convenient and harmful.
Electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. 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 ovens, televisions, computers and mobile phones.
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. 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.
Electromagnetic radiation is an important indicator of whether electronic products are qualified or not. For example, the labels on photocopiers show that these devices have been tested and certified by authoritative organizations, the most famous of which are "FCC" and "UL". Among them, FCC is an independent organization under the US Congress, which mainly judges the safety of products by analyzing the submitted data.
UL is the most authoritative safety laboratory in the United States and a large private institution engaged in safety testing and appraisal in the world, which has made great contributions to the protection of personal health and property safety.
Most of the imported photocopiers on the market have passed the market certification of "C" Canada and "US" America. We just need to use them with confidence and don't have to worry about any electromagnetic radiation to our bodies. No matter pregnant women or special people, only by knowing the necessary common sense can we calmly deal with all kinds of rumors.
