C
Terms in this set (364)
gadget - implosion type plutonium bomb
- project produced three bombs and the first of the three was the gadget used as
a test model
- had many wires attached to it
uranium bomb - uranium 235 - naturally occurring but requires enrichment
- "gun type" design that is less efficient and simpler
- requires large critical mass (lots of uranium)
little boy - hiroshima japan
- used 2 subcritical types of TNT
- 15 kilotons of TNT needed
plutonium bomb - plutonium 239
- more efficient but complex "implosion" mechanism
- smaller critical mass can be compact bomb design
plutonium 239 - not naturally occurring
- produced in reactors from uranium 238
fat man - nagasaki
- august 19th 1945
- 21 kilotons of TNT
- plutonium/implosion
t/f: the uranium bomb was never tested until it was used true
the first time
trinity bomb - was estimated to be 10 kilotons but revised up to 20 kilotons
- largest bomb to ever be detonated and more twice what was predicted
- left crated 5ft deep and 30 feet wide and mushroom cloud reached 7.5 miles in
height
trinity fall out - several ranches that had not been evacuated down wind were affected
- every year after 1945 the infant mortality rate increased to the East and
Northeast of the test site to the atlantic coast amounting to as much as 30-40
percent
decision to drop potsdam - determined to drop by Truman
- navy proposed that an ongoing blockade of Japan to eventually force surrender
and the army wanted to continue fire bomb raids bt the B-29 bombers
- broke Japanese code and saw that their defense plan included killing 200,000 to
1 million americans
, hiroshima - little boy = code name
- closest to the bomb immediately died and materials 6400 feet away ignited
- 9/10 people half a mile or less from the ground zero were dead
- people farther away experienced a heat flash and blast wave
- everything one mile away was destroyed and firestorm engulfed 4.4 square
miles of the city
death of hiroshima - 70,000 died as a result of the initial blast
- by the end of 1945, 100,000 people died over radioactive fallout
nagasaki - trumans order
- yield was 21 kilotons and 40% greater than little boy
- detonated above ground so spread further than before
breast cancer treatment - radiation - prone position has you laying down with only breast tissue sticking out helping
minimize the exposure of the healthy tissue
- there is also angled radiation with minimizes the amount of healthy tissue
exposure
- 25-28 treatments with 2 grays per treatment
operation crossroads - background - the US wanted to have military power, reliability, safety and prevent exposure
- cold war occurred and there was the arms race and they wanted to have the
biggest and best capabilites
operation crossroads - able-baker - first of many tests held at the marshall island
- headed by army instead of Manhattan project (disbanded)
- with heavy infighting in the armed forced, truman instituted a civilian review
able-baker opposition - pressure to cancel tests by Manhattan project because they said it was
unnecessary and environmentally dangerous
- tests would only prove shop survivability and not human exposure --> combat
this they brought animals on the tests
- secretary of state byrnes favored the test to make the soviets more pliable but
later argued for a delay and truman postponed he test for 6 weeks
marshall islands - 29 atolls and 5 islands
- 750,00 square miles of ocean with 70 square miles of land
marshall islands history - KEY: after WWII they deemed it a UN strategic trust territory, state-administered
by the US
late marshal islands history - 67 nucleus detonations in the marshall islands
- there was mutually assured destruction (MAD) in cold war
- US, Great Britain and USSR agreed to suspend nuclear weapon testing in 1958
main atoll tested in marshall islands - bikini and enewtok
