Witryna23 wrz 2024 · Radioisotopes (radioactive isotopes or radionuclides or radioactive nulcides) are used in two major ways: either for their radiation alone (irradiation, nuclear batteries) or for the combination of chemical properties and their radiation (tracers, biopharmaceuticals). Tracer Applications Witryna10 kwi 2024 · Isotopes are created through natural processes such as radioactive decay, cosmic ray interactions, and nuclear fusion reactions in stars. For example, carbon-14 is created in the Earth’s upper atmosphere when cosmic rays interact with nitrogen atoms. Isotopes can also be created artificially through nuclear reactions.
