Nuclear physics encompasses various fields, including theoretical and experimental branches, with distinctions between low-energy and high-energy physics. Many professionals in nuclear physics work in academia, industry, or government, often focusing on areas like nuclear structure and gamma-ray spectroscopy. Demand for nuclear physicists in industry is primarily linked to nuclear power and military applications, with roles often overlapping with nuclear engineering. A PhD in nuclear physics can lead to positions in health and environmental sectors, such as waste analysis. Opportunities also exist in medical physics and imaging for those with relevant educational backgrounds.
