Web6 apr. 2024 · We discuss 99m Tc imaging and the supply chain of 99 Mo in chapter 2. The new production scheme of medical radioisotopes, such as 99 Mo, 64 Cu and 67 Cu, using accelerator neutrons is introduced in chapter 3. The development of separation methods of 99m Tc from 99 Mo, and 64 Cu and 67 Cu from Zn samples are given in chapter 4. WebIn the nucleus of each atom of uranium-235 (U-235) are 92 protons and 143 neutrons, for a total of 235. The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts.
