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.
Describe the decay of a radioactive substance in terms of its decay constant and half-life; Use the radioactive decay law to estimate the age of a substance; Explain the natural processes that allow the dating of living tissue using 14 C
9 de may. de 2024 · Radioactivity is the property of some nuclei to emit energy and particles spontaneously. Learn about the types of radioactivity (alpha, beta, gamma, etc.), their applications, and their rates of decay.
Nuclei that have unstable n:p ratios undergo spontaneous radioactive decay. The most common types of radioactivity are α decay, β decay, γ emission, positron emission, and electron capture. Nuclear reactions also often involve γ rays, and some nuclei decay by electron capture.
Learn what radioactive decay is, how it occurs, and what types of radiation and decay modes exist. Explore the natural and artificial sources of radioactivity, the decay law, and the radioactive decay chain.
22 de abr. de 2024 · Learn what radioactive decay is, how it occurs in unstable atoms called radionuclides, and how it produces ionizing radiation. See examples of decay chains for uranium and thorium.
26 de jul. de 2022 · Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements...
