8、rization of electronic products make electromagnetic interference a serve problem.Electromagnetic radiation is a universal physical phenomenon which is generated by the electric charge movement. Nearly all of the household appliances especially mobile phone, TV, computer and so on can radiate electr
9、omagnetic waves, so electromagnetic waves surrounded us all day long. Some people refer to them as “invisible pollution.”There are three main kinds of hazards that electromagnetic radiation can make as follows: it can influence the normal operation of various electronic devices; electromagnetic leak
10、age of information and hang over national security; it influences our body balance, even harmful to our health and metabolize. Therefore, the electromagnetic pollution is known as one kind of environmental pollution. We must take measures to protect ourselves and this attitude is becoming more and m
11、ore popular.There are many measures that we can take to raduce or avoid electromagnetic radiation.But wearing anti-radiation clothes seems to be the convenient way.With the development of the textile industry, functional fabrics and functional textiles were known by consumers, and electromagnetic sh
12、ielding fabric is a large kind of those products. These textiles have good electromagnetic shielding effect, it can protect us from lots of harmful electromagnetic radiation. The electromagnetic shielding 6fabric has a long history until now. Today, there were many kinds of electromagnetic shielding
13、 clothes, the main radiation protection products on the market include maternity clothes,some frocks,childrens wear,etc.While the public havent realized the injury that the electromagnetic radiation could cause and the measures we coule take.Data analysis On the question “Do you think induction cook
14、er can produce radiation?” we received 99 answers. 701118ABC系列1Among these answers,70 students chose A(yes), accounting 70% of all the questionnaires. 11 students chose B(No),accounting 11% of all the numbers and the rest of the students chose C(I dont know.) Of course,the induction cooker has radia
15、tion.That means that there are 30% people havent realized the induction cookers radiation.On the question “Do you think mobile phone can produce radiation?” we received 99 answers.79810ABC系列1Among these answers,98 students chose A(yes), accounting 98.5% of all the questionnaires. Only 1 student chos
16、e B(No),accounting 1% of all the numbers.Of course,the mobile phone has strong radiation.That means that nearly all of the people have realized the mobile phones radiation.On the question “Do you think computer can produce radiation?” we received 99 answers.9720ABC系列1Among these answers,97 students chose A(yes), accoun
