kärnvapenstridsmedel
Kärnvapenstridsmedel refers to the explosive material used in nuclear weapons. These are typically fissile materials like enriched uranium or plutonium, which can sustain a nuclear chain reaction. When a critical mass of these materials is rapidly assembled, a nuclear explosion occurs. The process involves the splitting of atomic nuclei (fission) or the merging of atomic nuclei (fusion), releasing immense amounts of energy. Fission weapons, like those used in Hiroshima and Nagasaki, rely on fissionable isotopes of uranium or plutonium. Thermonuclear weapons, or hydrogen bombs, use a fission explosion to initiate a fusion reaction involving isotopes of hydrogen, such as deuterium and tritium, leading to an even more powerful explosion. The design of the weapon determines the yield, or explosive power, of the kärnvapenstridsmedel. The development and possession of these materials are subject to international treaties and agreements aimed at nuclear non-proliferation and disarmament. The effects of nuclear explosions include blast, heat, and radiation, with long-term consequences such as radioactive fallout.
