. Modern life is inseparable from electrical products. It not only brings convenience to us, but also releases terrible radiation. Recently, there is a saying spread on the Internet that taking off hair dryers, refrigerators, computers, mobile phones and other electrical appliances is a “hat” with high radiation, and desk lamps have become a new generation of “king of radiation”. The Post said: “the desk lamp is the king of radiation of household appliances, because it will release very high radiation in an instant.” So, is this statement true?
citizens: most people do not know that the desk lamp has radiation
. Among many citizens interviewed, only the mother of one child said that she knew that the desk lamp has radiation.
“does the desk lamp also have radiation? I haven’t heard of it before. ” The table lamp used by Ms. Qi, a citizen of Changchun, can be clamped anywhere. In order to take care of the children, she often clamps the table lamp at the head of the bed and uses this small table lamp to replace the room lamp at night. Mr. Shi, a citizen, has never heard that desk lamps produce radiation. Mr. Shi said: “among all household appliances, it’s too easy to find appliances with radiation, but I wouldn’t think of desk lamps.”
among many respondents, only one child’s mother said she knew that the desk lamp has radiation. “My daughter is only eight months old. I know that the desk lamp has radiation, so I put it away for a long time. If necessary at night, I will open the curtains and use the outside light.”
power staff: desk lamps also have radiation
according to relevant reports, the state stipulates that the radiation of household appliances shall not exceed 0.4w/m2. According to the test of professional instruments, among household appliances, the radiation value of refrigerator is about 0.02 w / m2, TV is 0.04 w / m2, notebook is 0.01 w / m2, microwave oven is 0.2 w / m2, hair dryer is 0.008 w / m2, and the radiation value of desk lamp is about 436 w / m2.
“the desk lamp must have radiation.”
staff of Yanbian power supply company of Jilin Electric Power Co., Ltd. told reporters that many people do not know that desk lamps and eye protection lamps have electromagnetic radiation. They simply believe that only household appliances such as computers, mobile phones and microwave ovens have electromagnetic radiation. The staff member said: “in fact, as long as there is current passing through, there will be electromagnetic radiation. Even when some household appliances are not turned on, as long as the power cord is plugged into the socket, there will be electromagnetic radiation around them. ”
how high is the radiation of desk lamp compared with TV, computer, microwave oven and other electrical appliances? A professional in Xi’an tested this. The results showed that the radiation of mobile phones, computers, electric fans, ordinary electric lamps, refrigerators, microwave ovens, wireless routers and other electrical equipment was lower than the national radiation safety standard, but the value of eye protection table lamps exceeded the standard by more than twice. According to statistics, the radiation of eye protection desk lamp is nearly 6 times that before the mobile phone is connected; Compared with mobile phone calls, it is as high as 50 times.
it is also reported that the state stipulates that the radiation of household appliances shall not exceed 0.4 w / m2. According to the test of professional instruments, among household appliances, the radiation value of refrigerator is about 0.02 w / m2, TV is 0.04 w / m2, notebook is 0.01 w / m2, microwave oven is 0.2 w / m2, hair dryer is 0.008 w / m2, and the radiation value of desk lamp is about 436 w / m2.
expert: the table lamp only has very high instantaneous radiation
according to experts, because there are ballasts in the mainstream table lamps on the market, its instantaneous radiation value is also very high! Although the radiation value of the desk lamp is high, its attenuation is also fast, that is, the farther away from the desk lamp, the lower the radiation value.
according to the staff of China Radiation Research Institute, “the eye guard table lamp is not only a luminous lamp, but also electromagnetic radiation near the lamp tube, lamp pole, circuit board and power connection line. Especially near the circuit board, electromagnetic radiation is the most serious. ”
according to experts, because there are ballasts in the mainstream table lamps on the market, its instantaneous radiation value is also very high! Although the radiation value of the desk lamp is high, its attenuation is also fast, that is, the farther away from the desk lamp, the lower the radiation value. When the distance from the table lamp is 10cm, the radiation value is 4.5w/m2, and when it is 15cm, it is sharply reduced to 0.3w/m2, which is completely within the safe range.
it can be seen that the online rumors are true. Experts remind that desk lamps are high radiation appliances hidden around us, but because their radiation attenuation is very fast, they should keep a safe distance when using them.
