Which of the following isotopes is normally fissionable?
Correct answer: C. U-233
- A. U-238
- B. Np-239
- C. U-233
- D. He-4
Explanation
Uranium-233 (U-233) is indeed fissionable and can undergo nuclear fission reactions. U-233 is a fissile isotope, meaning it can sustain a nuclear fission chain reaction. When bombarded with neutrons, U-233 nuclei can split into two or more smaller nuclei, releasing a significant amount of energy along with additional neutrons. This process is known as nuclear fission.U-233 can be produced artificially by irradiating thorium-232 (Th-232) with neutrons. Th-232, which is naturally abundant, absorbs a neutron and undergoes a series of nuclear reactions, eventually transforming into U-233.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
