ionium230

Ionium230, also known as I230, is a synthetic isotope of thorium with the atomic number 90 and mass number 230. It is a member of the actinide series and is produced through nuclear reactions, typically by bombarding thorium-232 with neutrons. Ionium230 has a half-life of approximately 75,400 years, making it one of the longest-lived isotopes in the actinide series. Its primary decay mode is alpha decay, resulting in the formation of uranium-226. Ionium230 is of interest in nuclear chemistry and geochemistry due to its long half-life and its role in the thorium decay series. It is not found naturally on Earth but can be synthesized in nuclear reactors or particle accelerators. The isotope has potential applications in nuclear medicine and as a tracer in geochemical studies. However, its use is limited by its long half-life and the challenges associated with handling and detecting such a long-lived isotope.
