Radioactive Decay & Half-life

Sort by:
Gives a detailed description on radioactive decay and it's equation. It also provides a simulation for students to work with to better visualize the concept.

This website explains alpha and beta decay. It also goes a little into how far each can penetrate, along with nuclear binding energies. Website is definitely for high school or higher.

This website introduces the object that contains almost all of the mass in the universe, the atomic nucleus. Antimatter, beta rays, fission and fusion, the structure of the atomic nucleus, how elements on the earth were produced, how we use the nucleus in every day life, and the effects of radiation in the environment are among the topics.
