  1. ICP Half-Life Centsium Lab 10/1/12

  2. Warmup • Which is more stable? A sample with a half-life of one day, or a sample with a half-life of one week? • Write an equation for the beta decay of thorium-234. • How many half-lives must a radioactive sample go through before it is at 25% of its original amount?

  3. Agenda • CentsiumLab • Time to work on half-life problems worksheet • Homework: “Half-Life Problems” Worksheet from Friday

  4. Centsium Lab Pointers • Keep adding your decayed to the number of decayed before. • Do not lose pennies. A missing penny is one point off your group’s lab grade. • Lay out your pennies in two 5x5 squares before putting them up at the end, so that I can check that you have them all.
