Alpha Decay analyze Polonium nucleus. Watch alpha particles escape from a Polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life. (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)

Sample Learning Goals
1. Explain alpha radiation in terms of alpha particles tunneling out of the nucleus.
2. Explain the concept of half life, including the random nature of it.
3. 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).
