radioisotopi

Radioisotopi, also known as radioactive isotopes, are atoms of a chemical element that have an unstable atomic nucleus. This instability means that the nucleus will spontaneously undergo radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays. This decay process transforms the parent radioisotope into a different nuclide, which may be a stable isotope or another radioisotope. The rate at which a radioisotope decays is characterized by its half-life, the time it takes for half of the radioactive atoms in a sample to decay. Half-lives can range from fractions of a second to billions of years, depending on the specific radioisotope.

Radioisotopi are produced through various methods, including natural radioactive decay found in some elements, neutron activation in nuclear reactors, and particle accelerators. Their unique properties, particularly their radioactivity and predictable decay rates, make them valuable in a wide array of applications. In medicine, radioisotopi are used in diagnostic imaging techniques like PET scans and SPECT scans, as well as in radiotherapy for cancer treatment. In industry, they are employed for gauging thickness, sterilizing equipment, and in non-destructive testing. Scientific research heavily relies on radioisotopi for dating ancient artifacts and geological formations (radiometric dating), tracing chemical pathways in biological and environmental systems, and studying nuclear processes. The safe handling and disposal of radioisotopi are paramount due to the potential hazards associated with radiation exposure.
