Why is the radiation of mouse and keyboard bigger than that of monitor?

At a distance of two feet, the radiation generated by 802. 1 1b wireless mouse, keyboard and other devices is only 2 microwatts per square centimeter (1 microwatt is one millionth of a watt). The 802. 1 1g product with higher performance releases less radiation. The FCC of the Federal Communications Commission stipulates that as long as the radiation of wireless network equipment is limited to 0/000 microwatts per square centimeter/kloc, it is safe. Therefore, even if dozens of wireless devices are used in a room at the same time, it will not cause harm to the human body. In fact, due to the popularity of electronic equipment, we are constantly exposed to the radiation generated by electronic equipment, such as TV, radio and microwave ovens. Network products such as mobile phones and wireless mouse and keyboard are only concerned by everyone because of their working principles.

Experts said: "The place that produces the most electromagnetic waves is the plug-in, and the wiring of the keyboard conforms to the problem of leaking electromagnetic radiation to the surrounding area." Cui Yi of North China Institute of Computing Technology thinks: "Because of the leaked electromagnetic radiation, the keyboard is the most easily intercepted and copied device besides the monitor."

Do you know the amount of radiation from computers?

1, keyboard 1000 V/m

2. Mouse 450V/m

3. Screen 2 18V/m

4. Host 170V/m [/color].

The keyboard and mouse are the most harmful to human body from computer radiation? 2007-02-27 2 1:03 Why does the keyboard and mouse of the computer have electromagnetic radiation? Because they realize all functions by generating alternating signals through the alternating electric energy of the host computer, they can generate low-frequency radiation.

Simply put: because the keyboard and mouse are connected to the host. If it is a wireless keyboard or mouse. Then there is almost no electromagnetic radiation, very small.
