Did you know?
WebIonizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation. Is alpha the most ionising? Web6 jul. 2024 · Alpha particles, beta particles, and gamma rays are all forms of ionizing radiation, but they have properties that differ from each other. For example, alpha particles are positively charged, beta particles are negatively charged, and gamma rays have no electrical charge. Of the three types of radiation, alpha particles are the easiest to stop.
