, more commonly referred to as electromagnetic radiation , consists of energy waves rather than physical particles. Unlike particulate radiation (such as alpha or beta particles, which have mass), nonparticulate radiation is composed of oscillating electric and magnetic fields that travel at the speed of light. Key Characteristics

High-energy waves that can strip electrons from atoms, potentially causing DNA damage.

Used for communication (cell phones, Wi-Fi) and heating food. What is Radiation? - International Atomic Energy Agency

Frequently used in medical imaging to view internal structures.

Highly penetrating radiation often used in cancer treatment or emitted during radioactive decay.

It travels in a wave-like pattern and can move through a vacuum, such as outer space.
