Half life

  1. 1. 7.2 – half life daughter isotope | decay curve | half life | parent isotope | radiocarbon dating
  2. 2. half life and radiocarbon dating • half life - amount of time it takes for an isotope to become half of its value • radiocarbon dating - measuring the age of an object by the amount of carbon 14 remaining • A machine called accelerator mass spectrometer is used for radiocarbon dating
  3. 3. decay curves • decay curve - curved line on a graph that shows the rate the radioisotope decays at • every decay curve looks the same, only the half life would differ depending on the isotope Decay curve for mercury-209
  4. 4. parent and daughter isotopes • Daughter isotope - stable product of radioactive decay • Parent isotope - the isotope going through radioactive decay Common isotope pairs
  5. 5. arc reactor making: • http://www.youtube.com/watch?v=4OUKPuR X9Ek Suit first flight : • http://www.youtube.com/watch?v=ZwOxM0- byvc
  6. 6. 7.3 – nuclear reactions chain reaction | fission | fusion | nuclear equation | nuclear reaction
  7. 7. fission • Fission - split of bigger nucleus into smaller nuclei | energy | subatomic particles [ protons | electrons | neutrons ] • The power released from fission is used to power our current lifestyles
  8. 8. nuclear reactions + equations • Nuclear equation - equation demonstrating radioactive decay [ temperature | density | pressure ] • Nuclear reaction - a process a nucleus goes through when loosing or gaining particles energy Quick guide to writing nuclear equations writing nuclear equations: -sum of mass stays the same on both sides -sum of charges stays the same
  9. 9. chain reactions • Chain reaction - an event in which one reaction initiates another Uranium- 235 chain reaction
  10. 10. CANDU reactor • “ canadian deuterium uranium ” reactor • one of most safe in the world • produces heat using : diagram of CANDU reactor
  11. 11. fusion • Fusion - 2 low mass nuclei coming together to form a bigger nucleus - the arc reactor uses fusion to power itself - arc reactor supposedly relies on a Pd-103/Pd-107 radio- isotopic decay cell to produce electrical current the sun’s fusion process
