Atomic bomb dropped on Hiroshima, Japan
- For example, the atomic bomb dropped on Hiroshima, Japan, in 1945, containing only about 64 kg (140 pounds) of highly enriched uranium, released energy equaling about 15 kilotons of chemical explosive. That blast immediately produced a strong shock wave, enormous amounts of heat, and lethal ionizing radiation.

Oct 12, 2024 · A nuclear weapon is a device designed to release energy in an explosive manner as a result of nuclear fission, nuclear fusion, or a combination of the two. Fission weapons are commonly referred to as atomic bombs, and fusion weapons are referred to as thermonuclear bombs or, more commonly, hydrogen bombs.

Mar 1, 2022 · Nuclear bombs involve the forces — strong and weak — that hold the nucleus of an atom together, especially atoms with unstable nuclei. There are two basic ways that nuclear energy can be released from an atom. In nuclear fission, scientists split the nucleus of an atom into two smaller fragments with a neutron.
Nuclear warfare, also known as atomic warfare, is a military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result.
Jul 21, 2012 · A nuclear weapon is a device which rapidly releases nuclear energy, either through fission (as in the bombs dropped on Hiroshima and Nagasaki) or a combination fission and fusion (as in a thermonuclear or hydrogen bomb).
