To increase understanding of the concept of radioactive nuclei and their decay products


This lesson plan is part of the Anti-Matter Teaching Module (see related documents).  
Duration of lesson:  approximately 30 minutes.  ( duration may vary depending on how it is used)
Care has been taken to ensure that the mathematical knowledge required for students to successfully complete these lesson plans harmonizes with that which is expected of students in the 9th and 10th forms, according to a representative sample of national curricula. For some of the more calculation-intensive lesson plans, teachers may find the Background Materials helpful. Teachers may also discover that the required calculations can provide an opportunity for training in the use of calculators and/or computer graphing programs.
This lesson uses a medical application of antimatter, the PET scan, as a way of introducing the concept of radioactive nuclei (in this case, positron-emitters) and their decay products.
Upon the completion of this lesson, the student shall:
-Be aware that certain nuclei are unstable, and that they become stable through radioactive decay
-Understand how antimatter (in the form of positrons) can be produced by the decay of certain radioactive nuclei
-Understand how positrons are used in a PET scan
