Which of the following statements concerning nuclear fission is correct?

Question

Quizplus · Accepted Answer

Neutrons play a crucial role in the nuclear fission process, acting as both reactants that initiate the fission of heavy nuclei (like Uranium-235) and products that are released during the fission process. These released neutrons can then initiate further fission reactions, leading to a chain reaction. Uranium-238 is not the most important fissionable isotope; rather, Uranium-235 is more commonly used for fission in nuclear reactors due to its ability to easily undergo fission when struck by a neutron. Nuclear fission is not typically used in diagnostic procedures in nuclear medicine; instead, nuclear medicine primarily utilizes radioactive decay processes, such as positron emission or gamma emission, from isotopes like Technetium-99m or Fluorine-18.
