Radiation
Radiation refers to the energy that travels through space in the form of waves or particles. It includes a range of phenomena, from visible light and radio waves to more energetic forms like X-rays and gamma rays. There are two main types: ionizing radiation, which can remove electrons from atoms and potentially harm living tissues (like X-rays), and non-ionizing radiation, which typically has lower energy and includes radio waves and visible light. Radiation occurs naturally in the environment and can also be produced by human activities, such as medical imaging and nuclear power generation.

Radiation refers to the emission and propagation of energy in the form of particles or waves. This can include visible light, radio waves, ultraviolet light, X-rays, and gamma rays. It occurs naturally, such as sunlight warming the Earth, or can be produced by man-made sources like X-ray machines. Radiation can be harmless, like sunlight, but some forms, particularly high-energy radiation, can be harmful to living organisms by damaging cells and DNA. Understanding radiation is important for medical imaging, safe use of technology, and protecting health from excessive exposure.
