Non-ionizing radiation refers to a type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules. This means it cannot remove tightly bound electrons from their orbits, which is a key characteristic of ionizing radiation. Examples of non-ionizing radiation include visible light, radio waves, and microwaves, all of which are commonly encountered in everyday life. Non-ionizing radiation is generally considered less harmful than ionizing radiation, such as X-rays or gamma rays, which can cause cellular damage and increase cancer risk. While non-ionizing radiation can still produce effects like heating tissues, it is typically used in various applications, including communication technologies and medical imaging.
