Global Nuclear Security refers to the measures and policies implemented to prevent the proliferation of nuclear weapons and ensure the safe handling of nuclear materials. This involves international cooperation among countries, organizations like the International Atomic Energy Agency (IAEA), and treaties such as the Nuclear Non-Proliferation Treaty (NPT). The goal is to reduce the risk of nuclear terrorism and ensure that nuclear technology is used for peaceful purposes. Efforts in global nuclear security include securing nuclear facilities, enhancing border controls, and promoting transparency among nations. Countries work together to share information and best practices, aiming to create a safer world. Initiatives also focus on the responsible disposal of nuclear waste and the protection of sensitive materials from falling into the wrong hands.
