Cosa ce dentro la bomba atomica?
Caratteristiche costruttive. Una bomba atomica è formata da un nocciolo metallico di alcune decine di chilogrammi di uranio arricchito oltre il 93% (uranio "weapon-grade"), oppure di qualche chilogrammo di plutonio contenente almeno il 93% dell'isotopo 239 (plutonio "weapon-grade").
Why is the Little Boy bomb called Little Boy?
- Little Boy was named by others as an allusion to Thin Man since it was based on its design. Because uranium-235 was known to be fissionable, it was the first material pursued in the approach to bomb development. As the first design developed (as well as the first deployed for combat), it is sometimes known as the Mark I.
How much did the Little Boy atomic bomb weigh?
- ■ This gun-type uranium bomb, nicknamed Little Boy, weighed 9,700 pounds. ■ The bomb was dropped on Hiroshima, Japan, Aug, at 8:15 AM. ■ A B-29 dropped the bomb from 31,000 feet.
Where were the Little Boy and Fat Man bombs?
- These bombs would be Little Boy and “Fat Man,” which were later dropped over Hiroshima and Nagasaki, respectively. While most of the work on this project was done in a secret lab in Los Alamos, New Mexico, additional facilities were established in Oak Ridge, Tennessee; Chicago; Washington state; and British Columbia.
How did they make the Little Boy fission bomb?
- Little Boy. Fission was accomplished by shooting a hollow cylinder of enriched uranium (the "bullet") onto a solid cylinder of the same material (the "target") by means of a charge of nitrocellulose propellant powder. It contained 64 kg (141 lb) of enriched uranium, although less than a kilogram underwent nuclear fission.
