X-rays are a form of electromagnetic radiation, a type of energy that travels in waves. They have a shorter wavelength and higher frequency than visible light. X-rays are commonly used in medical imaging to create images of the inside of the body. They pass through soft tissues but are absorbed by denser materials, such as bones, creating a contrast that forms an image.
X-ray imaging helps in diagnosing fractures, infections, tumors, and other conditions. Additionally, X-rays have applications in various fields beyond medicine, including airport security, industrial inspection, and scientific research. Despite their usefulness, exposure to high doses of X-rays can be harmful, so their usage is carefully controlled and limited in medical and other settings to minimize potential health risks.« Back to Glossary Index
