Nuclear Decay and Half Life
You learned about ionizing and non-ionizing radiation while doing research for your foldable. Ionizing radiation is dangerous because it has the ability to knock electrons off of other atoms. There are 3 types of ionizing radiation listed in your book on page 66: alpha, beta, and gamma. We added one more type to the table, Positron Emission. Positron Emission is a type of Beta radiation. We added some other notes to the table as well. See Mrs. Stant to get these notes.
Half Life
The Half-Life of a radioactive element is the time it takes for half of a sample of that element to decay. We did an activity to discover the half-life of a sample of Candium. If you were not here for this activity, get the worksheet from Mrs. Stant or download it below and get the data for the table from another student in class.
