WebSep 7, 2024 · The alpha particle removes two protons (green) and two neutrons (gray) from the uranium-238 nucleus. Although the radioactive decay of a nucleus is too small to see with the naked eye, we can indirectly view radioactive decay in an environment called a cloud chamber. What daughter nuclide is produced from the decay of a thorium-232 atom? Th is an isotope of thorium with 138 neutrons. It was once named Radiothorium, due to its occurrence in the disintegration chain of thorium-232. It has a half-life of 1.9116 years. It undergoes alpha decay to Ra. Occasionally it decays by the unusual route of cluster decay, emitting a nucleus of O and producing stable Pb. It is a daughter isotope of U in the thorium decay series. Th has an atomic weight of 228.0287411 grams/mole. Th is an isotope of thorium with 138 neutrons. It was once named Radiothorium, due to its occurrence in the disintegration chain of thorium-232.

WebThe nuclides generated during the decay of the very long-lived natural radionuclides U-238 ( half-life 4.5 bn years), U-235 ( half-life 0.7 bn years) and Th-232 ( half-life 14 bn years) are in turn radioactive, and therefore decay again. Thus, the so-called decay chains are created which end only when a non-radioactive nuclide is formed. WebDec 13, 2024 · The radioactive isotopes in our bodies. The elements carbon, hydrogen, oxygen, or nitrogen make up about 96% of our body. The radioactive isotopes of these elements are very rare in nature. But on the other hand, we have a lot of these elements in our bodies. So overall there are a few thousand radioactive decays per second from …
