Mobile phones emit electromagnetic radiation, which is a form of energy that travels through space at the speed of light. This type of radiation encompasses a broad spectrum that includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Specifically, mobile phones primarily use radiofrequency (RF) waves to transmit information to and from cell towers.

Understanding that mobile phones are part of the electromagnetic spectrum helps to clarify the nature of the radiation they emit. The emissions from mobile phones are generally at low frequencies, which means they carry less energy compared to high-frequency electromagnetic waves like X-rays or gamma rays. This is crucial for understanding the discussions around potential health implications, as the energy levels associated with radio waves are significantly different from those of ionizing radiation, such as gamma rays.

The other types of radiation mentioned—beta particles, gamma radiation, and infrared radiation—have different properties and are generated from different sources. Beta radiation consists of high-energy, high-speed electrons or positrons emitted by certain types of radioactive decay, while gamma radiation is high-energy electromagnetic radiation emitted during nuclear reactions. Infrared radiation is primarily associated with heat and is used in various technologies like remote controls and thermal imaging, but is not the type of
