  1. The aftermath

  2. The atomic bomb • The atomic bomb changed the modern world. • The Americans dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki. • The two bombs both atomic, however they did use different materials. • Little boy used uranium. • Fat man uses plutonium.

  3. Little boy • Little boy was named after president Roosevelt. • At the moment of impact a super critical mass was formed triggering a nuclear chain reaction. • It weighed in at 3.9 tonnes

  4. Fat Man • Fat man was a little bigger than little boy. • It weighed in at 4.5 tonnes. • 64 explosive charges went off around the plutonium inner shell which lead to the nuclear reaction.

  5. Major energy forms • There were three major energy forms involved in the explosion. • There were three • Fireball • Shockwave • Radioactive • There is one vastly different element in these three parts to the explosion. • This is the radioactive element. As it is the most deadly over a prolonged period of time.

  6. Radioactivity • Hiroshima and Nagasaki had 200 different types of radioactive isotopes. • Black rain was produced 30 to 40 mins after the bombs were dropped. • This rain was sticky, dark and dangerously radioactive. • Living cells were attacked immediately after the explosion by induced radiation.

  7. Social damage • Many of the citizens who actually lived in both cities, particularly woman and children. • The initial death count that was done of bodies was between 42,000-93,000 in Hiroshima. • In Nagasaki a similar count of about 60,000-70,000 • Many people who were close to ground zero died within the first day due to the high radiation levels.

  8. The Facts • There was high counts of mortality immediately after the bomb. • 90 percent of people within 500m of ground zero died. • 1.5km from ground zero 1/3 of people died and 2/3 of people were causalities. • 2km away from ground zero 10 percent of people died and 90 perent were casualties. • 4km away from ground zero 10 percentof people were casualties.

  9. Stages • Acute stage- primary and secondary • Flash burns, scorch, contact and flame burns • Atomic bomb trauma • Blast injury, debris, bury under rubble, blast compression. • Radiation poising. • Radiation blood injury • Secondary radiation illness • Unhealed scars • Atomic bomb cataracts • Leukaemia • Cancers • Chromosomes changes • Genetic surveys

  10. After the bomb • The population was decimated after the atomic bomb. • For several years there was a steady growth due to the evacuated families returning home. • When people returned there was social chaos. • Shortage of food • Not adequate shelter • In 1946 there was extreme shortages of food. • This lead to the government evacuating 50,000 people to surrounding villages. • Villages had access to crops and more shelter.
