The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
This effect is most important for altitudes above 30 km, corresponding to less than 1 percent of sea-level air density. The effects of a moderate rain storm during an Operation Castle nuclear explosion were found to dampen, or reduce, peak pressure levels by approximately 15% at all ranges.
150,000–246,000. On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively. The bombings killed between 150,000 and 246,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 ...
WWII. Human Shadow Etched in Stone (人影の石, hitokage no ishi)[2] is an exhibition at the Hiroshima Peace Memorial Museum. It is thought to be the shadow of a person who was sitting at the entrance of Hiroshima Branch of Sumitomo Bank when the atomic bomb was dropped over Hiroshima. It is also known as Human Shadow of Death[1] or simply ...
Hibakusha (pronounced [çibaꜜkɯ̥ɕa] or [çibakɯ̥ꜜɕa]; Japanese: 被爆者 or 被曝者; lit. 'survivor of the bomb' or 'person affected by exposure [to radioactivity]') is a word of Japanese origin generally designating the people affected by the atomic bombings of Hiroshima and Nagasaki by the United States at the end of World War II.
e. 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.
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. [6]
