You must know some of the knowledge of everyday use of electrical appliances

Fluorescent bulbs, cordless phones, Bluetooth headsets, plasma TVs...

Modern technology products, such as mobile phones, also generate electromagnetic fields while providing convenience to people. Scientists call this kind of invisible, intangible, inaudible, and incomprehensible health killer "dirty electricity" (professionalally called "transient electromagnetic field"). The US "Prevention" magazine published a review article on December 8th to teach you how to minimize the "dirty electricity" hazard.

1. Avoid wireless as much as possible. Electromagnetic radiation generated by wireless electronic devices is cumulative. Try to choose wired Internet access, wired security devices and entertainment electronics; when you sleep, be sure to unplug the plug; keep the router away from your body and your child's bedroom.

2. Choose a safer bulb. Avoid using fluorescent bulbs that produce "dirty electricity", try to use LED or incandescent lamps; do not use a varistor (dimming) switch.

3. Stay away from the junction box. The electromagnetic radiation is the largest within the range of 0.9-1.2 meters from the main power line box. Therefore, places such as beds and sofas that are used for a long time should be kept at a safe distance from the wall, underground or the next-side junction box.

4. Use a wired telephone. Cordless phones generate as much radiation as they do during use. Avoid using digital enhanced cordless phones (DECT) supported by base and satellite systems. In particular, pay less attention to your child's use of a cordless phone or cell phone.

5. No Bluetooth wireless headphones. When you answer the phone, try to use a wired headset.

6. Change the left and right ears to the phone. Using a mobile phone in a weak signal area will produce more radiation. In addition, when using the mobile phone, try to change the ears around the ear.

7. Install the phone in your pocket with the battery facing out. The phone is best placed in the bag, because the phone radiation is generally in the range of 0.9 meters. When you put your phone close to your phone, it's best to choose "flying" or "offline" mode. And the battery side of the phone is facing out, and the keyboard is close to the side.

8. Don't use a notebook while charging. Many laptops generate strong electromagnetic fields during battery charging. Therefore, try to charge the battery and use it. When the laptop is recharged, keep away from the computer.

9. Remove the plug when the appliance is not in use. These include electronic alarm clocks, electric lights, and more. These appliances generate radiation when energized.

10. When changing the TV, it is best to choose the LCD monitor, plasma and old-fashioned CRT TV radiation are relatively large. Not only that, but plasma TVs also generate transient electromagnetic fields in home wires.
