What is nuclear physics and why is it important?

Nuclear physics is the field of physics that studies atomic nuclei, their interactions, and the forces that hold them together. It's crucial for understanding energy production, medical applications, and fundamental forces in nature.

Can you explain how nuclear fission works?

Nuclear fission is the process where a heavy nucleus splits into two lighter nuclei, releasing a significant amount of energy. This process is used in nuclear reactors and atomic bombs.

What are some applications of nuclear physics in medicine?

Nuclear physics has several medical applications, including radiation therapy for cancer treatment, diagnostic imaging techniques like PET scans, and the use of radioactive tracers.

What are the risks associated with nuclear energy?

The risks of nuclear energy include potential accidents, radioactive waste management, and the proliferation of nuclear weapons. Safety measures and regulations are crucial to mitigate these risks.

How does nuclear fusion differ from fission?

Nuclear fusion is the process where two light nuclei combine to form a heavier nucleus, releasing energy, while fission involves splitting a heavy nucleus. Fusion powers the sun, while fission is used in nuclear reactors.
