Ionizing radiation is a type of radiation that contains enough energy to ionize atoms and molecules by removing electrons from their outer shells, creating charged particles known as ions. This radiation can take the form of gamma rays, X-rays, and certain types of particles like alpha and beta particles. Ionizing radiation is commonly used in medical imaging, cancer therapy, and industrial applications, but it can also pose a health risk if exposure levels are too high. Research in this area focuses on understanding the biological effects of ionizing radiation, developing protective measures and technologies to minimize exposure, and exploring new applications for this powerful form of energy.
