1. Identify three radioactive elements or reactions of different types and write the nuclear reaction for each element.
2. Provide a short description (4-6 sentences) of the role of the radioactive element or reaction in the area of interest that you selected. Include information about the type of radiation emitted and the half-life that makes the element appropriate for the use (or a problem if you are looking at something that is detrimental).
