Hiroshima and Nagasaki By Jenny, Jessica and Susannah

3 Big Ideas 1.Manhattan Project 2.Significance of Bombing 3.Why?

Code Name: Manhattan Project

Einstein: Dear President Roosevelt Scientists: o Oppenheimer o Bohm o Fermi o Szilard Research: Oak Ridge 1st test: July 6, 1945

Test Weapons "Little boy": Uranium- 235 "Fat man": Plutonium- 239

The atomic bombing August 6, 1945: Hiroshima August 9, 1945: Nagasaki

In response to Pearl Harbor preemptive attacks

Surrendered After radioactive fallout Hirohito, Emperor

Little Boy 9,700 pounds directly killed 194,566,000 people destructive force 63 Tera-Joules

Nuclear Fission The atom splits critical mass- fissionable materials needed

Fissionable Materials start with U-235, U-233, Pu-239 formed isotopes U-235= U-236= Kr-92+ Ba-142 U neutron= 2 neutrons + Sr-92 + Xe-140+ Energy

Nuclear Chain Reaction Atom bombarded with nucleus process continues and triples sustained by neutron

Nuclear Weapon Primarily use Plutonium, Uranium USA, United Kingdom, France, China, Russia N.P.T
