Involving a nuclear power plant at Chernobyl, now in Ukraine, a combination of nuclear volatility and the disregard of several safety procedures caused an explosion of its fourth reactor, ending in the worldwide environmental and human catastrophe. Following the Chernobyl accident, the IAEA was forced to create a new branch of their organisation to
High-altitude nuclear explosion The Outer Space Treaty of 1967 banned the stationing and use of nuclear weapons in space. The Comprehensive Nuclear-Test-Ban Treaty of 1996 prohibits all kinds of nuclear explosions; whether over- or underground, underwater or in the atmosphere. US Government Films: High-altitude nuclear explosion High-altitude nuclear explosions are the result of nuclear weapons testing. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962. The strong electromagnetic pulse (EMP) that results has several components. In the first few tens of nanoseconds, about a tenth of a percent of the weapon yield
