Radioactive decay - Wikipedia
Radioactive 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, beta, and gamma decay.
Radioactive Decay - Science Facts
2024年8月12日 · Radioactive decay, also known as nuclear decay, radioactivity, or radioactive disintegration, is a fundamental process in nuclear physics. It is a process in which an unstable atomic nucleus loses energy to become stable.
10.4: Radioactive Decay - Physics LibreTexts
When an individual nucleus transforms into another with the emission of radiation, the nucleus is said to decay. Radioactive decay occurs for all nuclei with \(Z > 82\), and also for some unstable isotopes with \(Z < 83\).

2024年4月22日 · Radioactive decay is the emission of energy in the form of ionizing radiation. Example decay chains illustrate how radioactive atoms can go through many transformations as they become stable and no longer radioactive.
Radioactive decay: what it is, types, formula and examples
2023年9月25日 · Radioactive decay is a physical phenomenon that involves the spontaneous transformation of unstable atomic nuclei into more stable ones. This nuclear process plays a crucial role in nuclear physics and has significant implications in fields such as medicine and geological dating.
Radioactivity and the Types of Radioactive Decay - Science …
2021年5月30日 · Radioactivity is the spontaneous emission of ionizing radiation from nuclear decay and reactions. The three main types of radioactive decay are alpha, beta, and gamma decay, but there are other nuclear reactions responsible for radioactivity.
Radioactive Decay | Definition, Types & Laws | nuclear-power.com
Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.
Radioactive decay is the process in which an unstable nucleus spontaneously loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom of …

2023年1月10日 · That morphing process is called radioactive decay. In radioactive decay, there are lots of ways an unstable atom’s nucleus can transform to make it more stable — and smaller. Subatomic particles can transform. And decay reactions almost always involve giving off energy, radiation and more tiny particles. ttsz/iStock/Getty Images Plus.
