  • Alpha Decay
  • Half Life
  • Radiasi

Description

Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.

Contoh Tujuan Pengajaran

  • Explain alpha radiation in terms of alpha particles tunneling out of the nucleus.
  • Explain the concept of half life, including the random nature of it.
  • Begin to gain an understanding of the forces that work to hold an atomic nucleus together (strong nuclear force) and the forces that work to break it apart (Coulomb, i.e. electric charge, force).
