A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting gamma rays. Every chemical element has one or more radioactive isotopes.
30 Ιουλ 2020 · Radioisotopes are unstable forms of elements that emit radiation and transform into more stable ones. Learn how they are produced, used and regulated by the IAEA in medicine, industry and other fields.
Learn what radioisotopes are, how they are produced, and how they are used in medicine, industry and science. Find out about the common radioisotopes used in each field and their applications.
A radionuclide is a nuclide that has excess nuclear energy and undergoes radioactive decay. Learn about the natural, nuclear fission and synthetic sources of radionuclides, and their applications in nuclear medicine, industry and research.
26 Ιουν 2023 · For example, uranium -238 decays in a series of stages to form a number of radioactive isotopes, including radium-226 and lead-206. These isotopes are found in minerals and rocks, and their decay over time is used in radiometric dating to determine the age of geological and archaeological objects.
Learn what radioisotopes are, how they differ from stable isotopes, and how they are made by natural or artificial processes. Find out how radioisotopes are used in medicine, science and industry.
22 Φεβ 2024 · Key points. Radioactive decay occurs when a radioactive atom gives off radiation in the form of energy or particles. Radioactive atoms give off radiation to become more stable. There are four types of radiation given off by radioactive atoms.
