The piezoelectric blast gauges were thrown off scale and no records were obtained. The excess-velocity blast-yield measurement (precise measurement of the velocity of sound at the site of the explosion and then comparing it with the velocity of the blast wave) [126] provided among the most accurate measurements of the blast pressure. Another ...
In the initial microseconds after the explosion, a fireball is formed around the bomb by the massive numbers of thermal x-rays released by the explosion process. These x-rays cannot travel very far in standard atmosphere before reacting with molecules in the air , so the result is a fireball that rapidly forms within about 10 metres (33 ft) in ...
For the first time in nearly 60 years, Russian energy corporation Rosatom has released video of the most powerful nuclear bomb ever to be detonated on Earth, reported IFL Science. The enthralling ...
The atomic bomb explosion generated a windstorm several kilometers wide that carried ash, dust, and debris over the mountain ranges surrounding Nagasaki. Approximately 20 minutes after the bombing, a black rain with the consistency of mud or oil came down carrying radioactive material for one to two hours before turning clear. [227]
Despite the lethal radiation and blast zone extending well past her position at Hiroshima, [55] Takakura survived the effects of a 16 kt atomic bomb at a distance of 300 metres (980 ft) from the hypocenter, with only minor injuries, due mainly to her position in the lobby of the Bank of Japan, a reinforced concrete building, at the time.
A watch melted during the Aug. 6, 1945, bombing of Hiroshima, Japan, has sold for more than $31,000 at auction. The watch is frozen in time at the moment of the detonation of an atomic bomb over ...
The Washington Post wrote, “Stone's film is an eloquent, if harrowing, examination of the psychic and physical fallout of the testing, both on Bikinians and on unprotected American servicemen who were drenched in radioactive mists while monitoring the blasts. The most surreal footage comes from government archives -- never-before- seen film ...
Target Nevada Special Film Project (S.F.P.) 281 (1951) is an instructional documentary short film produced by United States Air Force (USAF). The film documents the story of the USAF support to the United States Atomic Energy Commission for 1949–1951 continental atom bomb tests.
