What Is Radioactivity? Definition and Types - Nuclear energy
WebRadioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.A material containing unstable nuclei is considered radioactive.Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma … WebNov 15, 2024 · The Science of Nuclear Power. Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. The nuclear energy harnessed around the world ... small town wrenches
