How much energy was in the atom bomb?

Answer 1

Rough estimates are about 12-14 kilotons of TNT, which is 50,208,000,000 to 58,576,000,000 kilojoule. A joule is the energy exerted by the force of one newton acting to move an object through a distance of one meter. A newton is the unit of force derived in the SI system, which is the International System of Units(abbreviated SI from the French le Système international d'unités.

And if you want a different conversion the energy given of had about 37,031,521,711,000 to 43,203,441,996 000 foot pounds of force

Answer 2

Chaotic conditions made accurate accounts most difficult. Some victims were vaporized instantly, many survivors were horribly disfigured, and death from radiation was uncertain-it might not claim its victims for days, weeks, months, or even years.

The initial death count in Hiroshima, set at 42,000-93,000, was based solely on the disposal of bodies, and was thus much too low. Later surveys covered body counts, missing persons, and neighborhood surveys during the first months after the bombing, yielding a more reliable estimate of 130,000 dead as of November 1945. A similar survey by officials in Nagasaki set its death toll at 60,000-70,000. (Its plutonium bomb was more powerful, but its destructive range was limited by surrounding hills and mountains).

Additional counts indicated high levels of short-term mortality in both cities:

-Over 90% of persons within 500 meters (1,600 ft.) of ground zero in both cities died.

-At 1.5 km (almost one mile), over 2/3 were casualties, and 1/3 died.

-Of those at a distance of 2 km (1.2 mi.), half were casualties, 10% of whom died.

-Casualties dropped to 10% at distances over 4 km (2.4 mi.)
