radioaaltosäteilyn

Radioaaltosäteily, often referred to as radio waves, is a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared radiation and shorter than microwaves. These waves occupy the frequency range from about 30 hertz (Hz) to 300 gigahertz (GHz). Radio waves are generated by accelerating electric charges, such as in an electrical circuit or by natural phenomena like lightning.

The behavior of radio waves allows them to travel long distances and diffract around obstacles. They are used extensively in modern technology for communication purposes. This includes broadcasting radio and television signals, mobile phone communication, Wi-Fi networks, and radar systems. Different frequencies within the radio wave spectrum are allocated for specific applications by regulatory bodies to prevent interference.

While generally considered non-ionizing, meaning they do not have enough energy to remove electrons from atoms or molecules, concerns have been raised regarding potential health effects of prolonged exposure to high-intensity radiofrequency radiation, particularly from devices like mobile phones. However, extensive research by scientific organizations worldwide has generally concluded that current exposure limits are safe, and no definitive adverse health effects have been established from typical usage.
