Question

Why doesn't my laptop emit radiation?​

Answer 1

Your laptop computer does emit radiation. In fact, your laptop emits several different kinds of radiation:

• 400 to 800 THz electromagnetic radiation. This is the visible light given off by the laptop's screen that makes it possible for you to see what the computer is displaying. Yes, ordinary visible light is a form of radiation.
• 10 to 100 THz electromagnetic radiation. This is the infrared radiation given off by all parts of the laptop due to their temperature, through the everyday process of thermal emission.
• 5 GHz or 2.4 GHz electromagnetic radiation. These are the radio waves given off by the WIFI antenna in the laptop, which are used to connect to a wireless network.
• 2.4 GHz electromagnetic radiation. These are the radio waves given off by the Bluetooth antenna in the laptop, which are used to connect wirelessly to peripheral devices such as a cordless mouse.
• Low frequency electromagnetic radiation. These are the radio waves that leak from the electronic circuitry inside the laptop.
• Nuclear radiation including gamma rays. This is the nuclear radiation emitted through the natural radioactive decay of atomic isotopes in the computer's materials.

Answer 2

These are the radio waves given off by the Bluetooth antenna in the laptop, which are used to connect wirelessly to peripheral devices such as a cordless mouse. Low frequency electromagnetic radiation. These are the radio waves that leak from the electronic circuitry inside the laptop.
