Video Clip: Radiation and Radioactive Decay

Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.

Take notes in your Science Notebook.

Video Clip: Alpha Decay

Tyler Dewitt explains what alpha decay is, how atoms go from stable to unstable, and practice problems with examples of alpha decay.

Be sure to write down steps to help you balance alpha decay equations.

Video Clip: Beta Decay

Sometimes known as Beta minus decay or Beta emission, this process is related to Positron decay. An unstable atom takes a neutron and turns it into a proton, creating a high-energy electron known as a Beta particle. This makes the atom more stable. In this video, Tyler Dewitt demonstrates the basics of Beta decay, and nuclear equations with Beta Decay.

Be sure to take notes for balancing these types of nuclear equations in your Science Notebook.
