Does the radiation from desk lamps really matter?

Lights have become an indispensable part of people's lives, and with the development of modern science and technology, more and more types of lights have gradually been invented. I believe everyone should have a desk lamp at home. Especially when children are doing homework, parents like to light a desk lamp for them because it helps them concentrate on their studies. But most people don’t know that desk lamps actually have a certain amount of radiation. So is the radiation from desk lamps really that great?

Citizens: Most people don’t know that desk lamps have radiation

Among the many citizens interviewed, only one mother said she knew that desk lamps have radiation.

"Does a desk lamp also emit radiation? I've never heard of that before." The desk lamp used by Ms. Qi, a Changchun citizen, at home can be clamped anywhere. In order to make it easier to take care of her children, she often clamps the desk lamp on the bedside and uses this small desk lamp instead of the room light at night. Mr. Shi, a citizen, had never heard that table lamps could generate radiation. He said: "It is easy to find electrical appliances that emit radiation among all the home appliances, but I would never think of table lamps."

Among the many citizens interviewed, only one mother said she knew that table lamps have radiation. "My daughter is only eight months old. I know that table lamps have radiation, so I put them away a long time ago and stopped using them. When necessary at night, I will open the curtains a little to use the light from outside."

Electricity worker: Desk lamps also emit radiation

According to relevant reports, the state stipulates that the radiation from household appliances cannot exceed 0.4 watts per square meter. According to tests with professional instruments, among household appliances, the radiation value of refrigerators is about 0.02 watts/square meter, televisions are 0.04 watts/square meter, laptops are 0.01 watts/square meter, microwave ovens are 0.2 watts/square meter, hair dryers are 0.008 watts/square meter, and desk lamps are about 436 watts/square meter.

"Desk lamps definitely emit radiation." A staff member of the 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 emit electromagnetic radiation. They simply think that only household appliances such as computers, mobile phones and microwave ovens emit electromagnetic radiation. The staff member said: "In fact, wherever there is electric current, there will be electromagnetic radiation. Even if some home appliances are not turned on, as long as the power cord is plugged into the socket, there will be electromagnetic radiation around them."

Compared with other electrical appliances such as televisions, computers, and microwave ovens, how high is the radiation from desk lamps? A professional in Xi'an conducted a test on this, and the results showed that the radiation from electrical appliances such as mobile phones, computers, electric fans, ordinary electric lights, refrigerators, microwave ovens, and wireless routers were all lower than the national radiation safety standard values. Only the eye-protection desk lamp exceeded the standard by more than two times. According to statistics, the radiation from eye-protection desk lamps is nearly 6 times that before the mobile phone is connected; compared with when the mobile phone is on the phone, it is as high as 50 times.

According to other reports, the state stipulates that the radiation from household appliances cannot exceed 0.4 watts per square meter. According to tests with professional instruments, among household appliances, the radiation value of refrigerators is about 0.02 watts/square meter, televisions are 0.04 watts/square meter, laptops are 0.01 watts/square meter, microwave ovens are 0.2 watts/square meter, hair dryers are 0.008 watts/square meter, and desk lamps are about 436 watts/square meter.

Expert: Desk lamps only emit very high radiation for a moment

According to experts, since the mainstream desk lamps on the market now have ballasts, their instantaneous radiation values ​​are also very high! Although the radiation value of the desk lamp is high, its attenuation is also very fast. In other words, the farther away from the desk lamp, the lower the radiation value.

A staff member of the China Institute of Radiation Research said: "Eye-protection desk lamps not only emit electromagnetic radiation near the light tube, but also emit electromagnetic radiation in the lamp pole, circuit board, and power connection line. Especially near the circuit board, the electromagnetic radiation is the most serious."

According to experts, since the mainstream desk lamps on the market now have ballasts, their instantaneous radiation values ​​are also very high! Although the radiation value of the desk lamp is high, its attenuation is also very fast. In other words, the farther away from the desk lamp, the lower the radiation value. When the distance from the desk lamp is 10 cm, the radiation value is 4.5 W/m2, and at 15 cm it drops sharply to 0.3 W/m2, which is completely within the safe range.

This shows that the online rumors are true. Experts remind that desk lamps are high-radiation electrical appliances hidden around us, but because their radiation decays quickly, a certain safe distance should be maintained when using them.
