What are nuclear proliferation concerns?

Nuclear proliferation concerns specifically refer to issues surrounding the unauthorized spread of nuclear weapons or technologies. This encompasses the fear that countries or non-state actors may acquire nuclear capabilities without proper regulation or oversight, potentially leading to increased risks of conflict, terrorism, and global instability. The emphasis on unauthorized spread highlights the significance of non-proliferation treaties and global efforts to control and monitor nuclear materials. Such concerns are pivotal in international relations and global security, as the presence of nuclear weapons in unstable regions or in the hands of rogue entities can escalate tensions and pose severe threats to world peace.

In contrast, the other options focus on different aspects of the nuclear field. The safety of nuclear plants, management of nuclear waste, and public health impacts, while critical issues, do not directly relate to proliferation. They are more aligned with nuclear energy operation, safety management, and environmental health than with the concerns over the spread of weapons and technology.
