Radioactivity | Definition, Types, Applications, & Facts
WEBMar 29, 2024 · Radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously. It is, in essence, an attribute of individual atomic nuclei. Radioactive decay is a property of several naturally occurring elements as well as of artificially produced isotopes of the elements.
Radioactive decay - Wikipedia
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, beta, and gamma decay.

Radioactive isotope | Description, Uses, & Examples | Britannica
WEBradioactive isotope, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. A brief treatment of radioactive isotopes follows. For full treatment, see isotope: Radioactive isotopes.
Radiation - Wikipedia
WEBThe international symbol for types and levels of ionizing radiation (radioactivity) that are unsafe for unshielded humans. Radiation, in general, exists throughout nature, such as in light and sound. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium.
Science Made Simple: What Is Radioactivity? - SciTechDaily
WEBJan 17, 2021 · What Is Radioactivity? Radioactivity 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.
Radioactivity Definition in Science - ThoughtCo
WEBSep 6, 2019 · Radioactivity 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.
DOE Explains...Radioactivity | Department of Energy
WEBRadioactive nuclei are nuclei that are unstable and that decay by emitting energetic particles such as photons, electrons, neutrinos, protons, neutrons, or alphas (two protons and two neutrons bound together). Some of these particles are known as ionizing particles. These are particles with enough energy to knock electrons off atoms or molecules.
