, 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
Frequently used in medical imaging to view internal structures. nonparticulate radiation
It travels in a wave-like pattern and can move through a vacuum, such as outer space. , more commonly referred to as electromagnetic radiation
Lower-energy waves that lack the power to ionize atoms but can cause thermal effects. which have mass)
Used for communication (cell phones, Wi-Fi) and heating food. What is Radiation? - International Atomic Energy Agency
Nonparticulate radiation spans a wide range of energies, categorized by their wavelength and frequency:
