  1. Aim: How is radiation used in the real world everyday?HAPPY NEW YEAR!! Do Now: Nuclear chemistry powerpointCopy notes (On my web page…go to www.johnbowne.org, click on Teachers and locate Osorio) Agenda: Housekeeping Review books have arrived! Work is returned…place in folders. Lab count as of Jan 1 is on Pupilpath…should have 15 labs. Ask me for makeup labs…should have 18 by end of Cycle 2 (Jan 20.) Makeup labs: “Band of Stability” and “Half life.” Makeup hw and missing work Get ahead! Read “Uses of radiation.” Test Friday?!?

  2. Aim: How is radiation used in the real world everyday? Half-life- time it takes for half a sample of a particular radioactive isotope to decay; the rate of nuclear decay. • Half-life is a constant value and is not affected by temperature or pressure. • The use of radioactive isotopes to determine the age of an object is called radioactive dating.

  3. Aim: How is radiation used in the real world everyday? Essential Questions: • Why do certain elements undergo radioactive decay and others don’t? • How do the nuclei of atoms stay intact if protons are positive, and like charges repel? • Describe the various types of radioactive decay in terms of charge, mass and “penetrating power.”
