radiostrålning

Radiostrålning, also known as radio waves, is a type of electromagnetic radiation with wavelengths longer than those of infrared radiation. It falls within the electromagnetic spectrum and is broadly defined as electromagnetic waves with frequencies of about 300 gigahertz (GHz) or less, corresponding to wavelengths greater than about one millimeter. Radio waves are produced by accelerated electric charges, typically in an antenna.

These waves are used extensively for communication, including broadcasting radio and television signals, as well as for mobile phone networks, Wi-Fi, radar, and satellite transmissions. The specific frequency or wavelength of a radio wave determines its properties and applications. For instance, lower frequencies can travel longer distances and penetrate obstacles more effectively, while higher frequencies can carry more information.

Radio waves have been crucial in the development of modern technology and continue to be a fundamental part of global communication infrastructure. They are a non-ionizing form of radiation, meaning they do not have enough energy to remove electrons from atoms or molecules, and are generally considered safe at typical exposure levels. Research into the potential biological effects of radio wave exposure continues, but established scientific consensus does not indicate significant health risks from everyday use of radio wave-emitting devices within regulatory limits.
