With the development of the communications industry and home appliance industry, the modern people in the enjoyment of the convenience of modern communication equipment and electrical appliances brought about by the comfortable at the same time, but also more and more from a variety of electrical appliances and communication equipment radiation, the more people are exposed to an increasing electromagnetic radiation in an environment where it is usually commonplace to see household appliances are also accused of being an invisible killer of indoor electromagnetic radiation, and how much should be adopted attitude to view and use of electrical appliances more and more attention by ordinary consumers. Electromagnetic radiation of the invisible killer, and household appliances of electromagnetic radiation harm in fact how much, exactly what attitude should be adopted to view and use of home appliances more and more by the ordinary consumers of home appliances attention.
What is electromagnetic radiation
We usually use electrical appliances and communications equipment, such as television, cell phones in the use of electric and magnetic fields in the interaction of changes in electromagnetic waves, electromagnetic propagation process at the same time there is electromagnetic energy to the outside world, this energy in the form of electromagnetic waves through the space propagation of the phenomenon becomes electromagnetic radiation. At present, electromagnetic radiation has become the fourth largest environmental pollution following water, air, noise, and has been included in the United Nations Conference on the Human Environment must control pollution.
Although the current home appliances are different degrees of electromagnetic radiation release, but on the human body exactly how much harm can be produced, there is a lack of real experimental basis, the general view that the electromagnetic field will interfere with the speed of cellular release and absorption of calcium, resulting in the production of cancer cells, and low-frequency radiation is an important cause of human cancers, reproductive disorders, genetic disorders, Alzheimer's disease, amnesia, while the Electromagnetic radiation is the most harmful to children, long-term exposure to electromagnetic radiation will increase the chance of children getting cancer.
Radiation intensity of general household appliances
At present, there are international and domestic institutions specializing in relevant research and testing, according to the International Health Organization's publicly available data we can understand the daily use of household appliances in the electric field and electromagnetic intensity.
From the above data, our daily use of home appliances mainly in the industrial frequency magnetic field radiation exceeds the standard, and is mainly manifested in the hair dryer, vacuum cleaner, electric shaver, fluorescent lamps and microwave ovens. And very often several kinds of electrical appliances may be used at the same time, and the strength of the magnetic field between them exists cumulatively in use. In some informal experiments, many people have found the existence of the phenomenon of group radiation, "'group radiation' will make the radiation frequency band is very wide, will increase the resonance between the equipment and the superposition of the radiated energy. When the energy reaches a certain level, the human body is simultaneously exposed to the thermogenic (higher frequency), non-thermogenic (full frequency band) and resonant effects of radiation (when the wavelength is proportional to the scale of the organism)." This also shows that the effects in radiation are far more widespread than is understood.
Scientific use of electrical appliances and electromagnetic radiation
Currently there is no specific standard for electromagnetic radiation of home appliances in China, generally using the international standards, there is no corresponding logo on the product and the indicators to illustrate the degree of radiation of the product, in the purchase of the product is unable to compare the degree of radiation of the product and judgement, the absence of such information so that consumers lack of sufficient understanding of the product, but also unable to make a comparison of the product. This lack of information makes consumers lack of sufficient understanding of the product, and can not make normal protection and avoid radiation in use.
For the radiation damage of home appliances, from the viewpoint of the current domestic academic session and the media's public opinion, the two attitudes are very different. At present, many media articles are also in the electromagnetic radiation as a general explanation of home appliances such as induction cookers, microwave ovens and other products such as the radiation produced by the radiation is considered to be relatively weak radiation, this radiation is much lower than the radiation of cell phones and other communications equipment, that can be used with confidence. And from the academic session of the general point of view, electromagnetic radiation long-term low-dose exposure is prone to health hazards, compared with foreign countries in Europe and the United States, China's population is larger, live more concentrated, the actual public received electromagnetic radiation exposure level than Europe and the United States. Although experts from an academic point of view that the objective existence of low-dose radiation hazards, but it is recommended to a relaxed mindset to deal with the radiation of electrical appliances, to the scientific point of view to use electrical appliances to avoid radiation.
Electromagnetic radiation is mainly produced by the coil and motor in the appliance, with the distance increases exponentially, so the best way to prevent radiation is to use away from the appliance, while avoiding the centralized placement of home appliances. Special populations in the use of household appliances to pay attention to the use of radiation protection facilities, and children as far away from the appliances.
Radiation from electrical appliances is a cool killer in the home
Home electricity bills have risen since the beginning of this month, with the rate of increase approaching 7.6 percent per kilowatt-hour. While calculating how to save electricity, do you have a basic understanding of the "side effects" of household appliances?
Household appliances are changing rapidly to improve the quality of life, in the market competition, "innovative" styles in the first rush to launch, many hastily rushed to the market, "new sales" products, from design, manufacturing to the shelves, they actually go through some of the What kind of quality control have they undergone? This, frankly speaking, the average consumer is not quite clear, and the key is, home is full of advanced electrical appliances, can anyone seriously think about the problem of electromagnetic radiation?
Hey, not everyone has a microwave oven at home, but certainly everyone has a TV at home. In addition to TVs and microwave ovens, there are also computers, refrigerators, air conditioners, cell phones, and so on.
Maybe you have heard that many household appliances produce electromagnetic waves of different strengths, wavelengths and frequencies when they are activated. If you use household appliances in an inappropriate way, you may expose yourself to electromagnetic radiation, which can pose a threat to human health.
Lack of awareness of electromagnetic radiation
While it is true that the radiation from electrical appliances is only trace, and will not cause significant harm to the body in the short term, manufacturers have not labeled their products in a certain period of time units of the radiation index at the same time that they guarantee the quality of their products?
Leigh Ming trading home appliances store manager Zhuang De'an said: "If the manufacturer labeled the electromagnetic radiation index, the knowledge of this area will be more careful to use, but the general do not know exactly what consumers, perhaps not dare to buy. Usually, the manual will have 'please pay attention to' or 'careful use' and other columns, although it is difficult to see manufacturers frankly admit that the goods have electromagnetic radiation, but in the use of the rules, often can be clever attention to a point."
In manuals, some instruct users to place appliances in appropriate places, while others are more direct in reminding of the need to turn off the power when not in operation. But in no case is there a note that this product has trace amounts of electromagnetic radiation, and it's better to stay away from it.
Electromagnetic radiation is a kind of cumulative damage, there is no way to find out which appliance the victim was exposed to or when, so it seems that no appliance manufacturer is responsible.
"Even if it is obvious that the radiation is emitted by which kind of electrical appliances, even if the complaint to the foreign manufacturers, that layer of formalities will take at least one or two years, and in the local consumer awareness of the electromagnetic radiation of electrical appliances is not enough, there is no such concept, almost never customers care, generally asked to understand is the price and power consumption. "
Thai authorities have banned children from using cell phones since it was confirmed not long ago that cell phones possess relatively serious electromagnetic radiation. The fact that cell phone radiation is quickly attracting attention may have something to do with the fact that it is the closest thing to the brain when it is used.
Electromagnetic radiation can penetrate the human body
Local Motorola public relations manager Chen Hui-ling said: "In fact, the company has long been aware of the problem of electromagnetic radiation generated by cell phones, and has therefore published a manual to guide the safer use of cell phones, including the fact that electromagnetic energy can have an impact on human health when wireless phones are in operation. The manual is written from the perspective of clearing up doubts. However, as far as I am aware, I have not come across any customer complaints, except for the media who have made inquiries to us about it."
It is evident that the nation is still not aware enough of electromagnetic radiation.
The frequency unit of electromagnetic wave is hertz (Hz).
You can never witness this "calm killer", which is colorless, tasteless and invisible.
When the magnetic field of electromagnetic waves oscillates at a frequency of more than 100,000 Hz, it poses a potential threat to the human body. However, according to international electrical industry standards, electrical appliances leave the factory, are subject to qualified electromagnetic radiation protection test, but, if we have many electrical appliances in the home are centrally placed, and often used together at the same time, then you will be exposed to the risk of overdose radiation.
