So, did "Little Boy" malfunction, or was it just an extremely inefficient design?[edit]

From this book that was recently released, it concurs with the statement of the article that just 7/10 of a gram of material underwent fission in the bomb, essentially "the bomb just blew apart in the air." Nodekeeper (talk) 12:29, 12 August 2014 (UTC)

1 "Approximately 600 to 860 milligrams (9.3 to 13.3 grains) of matter in the bomb were converted into the energy of heat and radiation."

2 "It contained 64 kg (141 lb) of enriched uranium, of which less than a kilogram underwent nuclear fission."

I assume that nuclear fission is the same than 'matter converting into the energy of heat and radiation'. Why does sentence 2 use a limit of a kilogram, istead of gram? — Preceding unsigned comment added by 130.60.69.144 (talk) 16:08, 25 March 2015 (UTC)

When a nucleus fissions, only a small proportion of its matter is converted into energy. Most of the matter in the fissioned nucleus ends up in the nuclei of the nuclear fission products and as neutron radiation. In Little Boy, a bit less than a kilogram of uranium fissioned. Of that kilogram, 600-860 mg of matter were converted into energy. The rest of the kilogram stayed as matter and became fission products and radiated neutrons.

Photos[edit]

Would a photo of the Little Boy replica at the Air Force Museum be helpful to the article? 21:02, 18 May 2015 (UTC)
