The predictions were made under simulated tactical nuclear war conditions aboard ship by Edward A. Schuert Following the detonation of the first atomic bomb, pre-war steel and post-war steel which is manufactured without atmospheric air, became a valuable commodity for scientists wishing to make extremely precise instruments that detect ...
The Tsar Bomba (Russian: Царь-бомба, romanized: Tsar'-bomba, IPA: [t͡sarʲ ˈbombə], lit. ' Tsar bomb '; code name: Ivan [5] or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs , a more compact size, a lower mass, or a combination of these benefits.
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
Calculations demonstrate that one megaton of fission, typical of a two-megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 miles) across for five minutes. Careful selection of the burst altitudes and locations can produce an extremely effective radar-blanking effect. [20]
The fallout gradually dispersed around the globe, depositing traces of radioactive material in Australia, India, Japan, and parts of the United States of America and Europe. It had been organized as a secret test, but Castle Bravo quickly became an international incident prompting calls for a ban on atmospheric testing of thermonuclear weapons.
The first target of nuclear weapons, the Mark I atomic bomb. The target was the Aioi Bridge across the Ōta River; it exploded several hundred yards off. Hiroshima was a city of 250,000, suffering 70,000 or so deaths immediately and up to 126,000 by the end of the year. Nagasaki, Japan
The fallout from the March 1954 Bravo test in the Pacific Ocean had "scientific, political and social implications that have continued for more than 40 years". [3] The multi-megaton test caused fallout to occur on the islands of the Rongerik and Rongelap atolls, and a Japanese fishing boat known as the Daigo Fukuryū Maru (Lucky Dragon). [3]
