Jounal 7 Science Behind the Atomic Bomb of the Time Period

 Part One
 
Dr. Sasaki has been the most interesting to me for the amount of lives he is working to save.  He has been taking people in and caring for them quick, only to get someone else in right after.  This shows his sympathy and his ability to care for others in the time of great need.  “At least ten thousand of the wounded made their way to the best hospital in town…”  We can learn that providing a service out of the goodness of your heart can be life saving.

Part Two
On August 6th, a B-29 titled the Enola Gay dropped a 5 ton atomic bomb over the city of Hiroshima.  The blast was equivalent to 15,000 tons of TNT, and it immediately killed 80,000 people.  In this time period, two types of nuclear weapons were designed.  The bomb, named Little Boy, was a gun type bomb, and the bomb dropped on Nagasaki named Fat Man, was an implosion type bomb.  The gun type used a very difficult to find, uranium 235 to function, while the implosion type was primarily plutonium and uranium 238.

The little boy was planned to explode at 580 meters above ground.  Because of this, there is no crater at ground zero.  When the bomb blew, the immediate repercussion was an intense fireball 370 meters in diameter with a 6,000 degree Celsius surface temperature.  Everything flammable in that area was instantly inflamed.  The radiation caused by the explosion had a lethal radius of 1.3 kilometers.  Over 6,000 people died from radiation related injures after having survived the initial blast.  The bomb was a truly unique and first of its kind experience for all the countries of this world.  It destroyed so many lives and it still has effects today.

  1. Dr. Sasaki was an incredible man and really worth appreciating. Could you imagine working in a hospital of such conditions and not going mad? I sure couldn't... the man had to be numb. I really love science and your research topic was very informative! You're pictures and statistics on the each eruption was very fascinating as well. To think that there were even survivors who were close to ground zero is remarkable. Wonder what ground zero would look like if we dropped one of the new humungous atomic bombs... I hope we never see that day.
