- Radioactive decay - WikipediaRadioactive 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.
- Radioactivity Definition in Science - ThoughtCoRadioactivity is the process by which an unstable atomic nucleus loses energy by emitting radiation. While radioactivity results in the release of radiation, not all radiation is produced by radioactive material. The SI unit of radioactivity is the becquerel (Bq). Other units include the curie, gray, and sievert.
- 31: Radioactivity and Nuclear Physics - Physics LibreTexts1472. OpenStax. The exploration of radioactivity and the nucleus revealed fundamental and previously unknown particles, forces, and conservation laws. That exploration has evolved into a search for further underlying structures, such as quarks. In this chapter, the fundamentals of nuclear radioactivity and the nucleus are explored.
- DOE Explains...Radioactivity | Department of EnergyRadioactivity is the release of energy from the decay of the nuclei of certain kinds of atoms and isotopes. Atomic nuclei consist of protons and neutrons bound together in tiny bundles at the center of atoms.
