Hangzhou this year’s cold winter to be more than in previous years, away from home, down clothes, UGG and the Lei Feng cap is the best IN the “cold Sambo.” At home, inside, heating is indispensable, of course, there are blanket. What is the time to remember blanket has been into our lives. Was a kid, every winter, Dad would go to my “quilt hole” that copper plug the “hot stove” and then later on replaced by a hot-water bottle. And the “hot stove”, hot-water bottle than the blanket obviously a lot easier, like when the heat on when the heat, but also eliminate the need for boil water, washed the tedious steps in irrigation. However, first blanket is charged, will be electromagnetic radiation. Could it be every night of the blanket close contact with us, in bringing us warm, it is also malicious manner against our body? Pregnant women, in the end can not use electric blanket? This winter Days, Anne was pregnant. Her husband is very considerate, keep Anne in the household, but also early in the bed covered with a blanket every night before drove a while, and then let Anne into bed. Anne incredibly happy, could not help but boast in front of the small sisters from her husband. However, the mention of the blanket, small sister exclaimed: “Do you still use electric blanket, ah, electric blanket, but there is radiation,nike free 5.0, you are now Huaizhuo pregnancy, and that is very dangerous ah!” Although I do not know true or false, Anne was terrified, and hastened to give her husband the blanket replaced with hot-water bottle. This reporter did a little online survey and found that one third of the User will be in the winter with blanket Among them, mostly girls. On the blanket of radiation, half of the netizens said “do not know”, there are two sixths of the User, said “I know, but still in use,” and only one-sixth of the User that blanket of radiation may have the body We, therefore, to use “hot-water bottle” instead. There is current there will be electromagnetic waves Electric blanket, knowing how strong the electromagnetic radiation in the end, we may wish to ponder what high school physics knowledge. How the electromagnetic waves generated? Want to know current will produce magnetic field changes in the magnetic field will generate electricity. Changes in electric and magnetic field changes constitute an inseparable unity of the field, this is the electromagnetic field, while the changes in the spread of the electromagnetic field formed in the space of electromagnetic waves. Electromagnetic waves generated surface water waves as the breeze in general a steady flow of external radiation, in fact, home appliances around us, more or less will produce electromagnetic radiation, the blanket is no exception. Electromagnetic radiation heats the water makes the body Electromagnetic waves on the human body there is definitely a hazard, Zhejiang University, Institute of electromagnetic field and wave to thank the teacher, said senior engineer, as to the harm of electromagnetic waves on the human body, the international community is still under study, but can be sure that the person who receive long-term electromagnetic radiation, may be drop caused by the human immune system, metabolism disorders, memory loss, early aging, skin and produce patches pox, rough, male and female fertility decline, women easy to menstrual disorders, miscarriage, or even to cause various types of cancer. Why are electromagnetic waves would cause so much harm to the human body? Xie teacher said: “We are more than 70% of the human body is water, water molecules by the electromagnetic radiation, will be of mutual friction, it will become hot, the body heats up, organs, the nervous system to work will certainly be affected.” “For example, we use mobile phone, mobile phones produce electromagnetic radiation, our brain exposed to radiation on the water get hot, then we will certainly be the work of the brain affected.” Electromagnetic radiation hazards to humans, one through the “water get hot,” to achieve, there is a kind of disorder is the body’s own electromagnetic field. The body’s organs and tissues are present weak electromagnetic fields, which are stable and orderly, and in the event of external electromagnetic interference, the weak electromagnetic fields in a state of equilibrium that will be destroyed, the body will follow the normal cycle of functional damage. Xie says that electromagnetic radiation on the human body injury is cumulative, long-term by the electromagnetic radiation, it may lead to qualitative change in the human body elements, which should arouse our vigilance. Blanket of the electromagnetic radiation is strong or not? Whether at home or away from home, we are inevitably exposed to electromagnetic waves. Strong radiation of electromagnetic waves are weak, too strong or too sustained, would harm the human body. Blanket how strong the electromagnetic radiation? “The most intuitive way is to look at the frequency of electric blanket, the frequency of the four parties and the strength of radiation can be said that is proportionate to the blanket of the frequency is 50 Hz,ugg classic cardy boots, this frequency is very small, in general, frequency of 300 MHz or above it may harm the human body, and a megahertz is equivalent to 106 Hz, so you see, blanket of radiation is very weak. “Zhejiang University Business Information and Electronic Engineering, Physics Teaching and Research Office, said Ma Tao. In addition to frequency, there is a way to see “the magnetic field strength,” the stronger the magnetic field strength, radiation, the more powerful, but this should be something more professional, not read the frequency is more intuitive. Magnetic field strength we use the letter B, said the unit often has three, one is the Tesla (T), one gauss (Gs), there is a milli-Gauss (mGs), 1T = 104Gs = 107mGs. Yesterday, Professor Ma has specialized in their own home, a double electric blanket, according to the label above the power and the resistance of a wire construction of a rough calculation, probably about 400 milli-Gauss. 400 milli-Gauss is what the concept? “The Earth’s own magnetic field strength generated there were probably 600 milli-Gauss, and we are on earth for generations to survive and multiply, so blanket 400 milli-Gauss magnetic field strength not to mention what effect on the human body.” Capped with a layer of radiation in the blanket of this useless Burkina Faso It seems that blanket is basically safe. “If you really do not worry, you can first open the electric blanket heating, and then turn off the electric blanket and then into bed, so that better.” Horse, Zhejiang University, Business teacher said. Online there are some radiation protection blanket, claiming that the heat resistance of a layer of radiation on the pad cloth, this layer of radiation effects of cloth, Ma teacher is not so optimistic about it. “We often see some of the Maternity radiation will block some of the radiation, such as a mobile phone wrapped in a Maternity inside, there will not be the signal. That is because cell phone radiation is a high-frequency radiation, maternity is also high-frequency radiation shielding. In fact, many shielding materials, only within a certain range of frequencies is the wavelength of radiation, or work, once over this wavelength, it may be rendered useless, maternity materials used, high-frequency radiation on the cell phone works, but not necessarily The low-frequency radiation on the blanket useful. ” The electric radiation much stronger than the electric blanket In addition to blanket the house which so many electrical appliances, electrical appliances which the radiation of the most powerful? “Microwave ovens and cell phone radiation our attention.” Zhejiang University teacher said Xie. “Microwave oven itself is to give food by microwave heating, the frequency of very high,nike free 3.0, there are 2500 MHz. So, microwave at work, it should not stray too close,cheap mens timberland boots, choose the good quality is also very important microwave radiation is not easy to leak.” “There is also a cell phone, cell phone power 1,800 megahertz,coogi mens hoodies, and we call, cell phone close to the brain, right brain affected seriously. Even in standby mode, mobile phones and base stations, or be connected, Therefore, radiation does not stop. ” As for the fixed-line telephone, TV in particular, LCD TVs, computers and other electrical appliances, to thank the teacher that the radiation is relatively small. But thank the teachers especially to say that outside of those colorful neon radiation is a great one, we walked pass by, do not stay too long.
