Objectives
To become familiar with the uses of Radioisotopes through use of the Internet.
To be able to use your knowledge and understanding of radioisotopes to contribute to the discussion board.
Background
According to our textbook, “radioisotopes are powerful tools for studying processes in biochemistry, medicine, material science, environmental studies and many other scientific and industrial fields.”
Below is a list of radioisotopes and their half-lives. You will be choosing one of these radioisotopes to explore in more detail.
Assignment
Choose one of the radioisotopes from the list or find a radioisotope that is not on the list but interests you.
Using your book and Internet resources, find five interesting pieces of information on the radioisotope you selected. Suggested pieces of information may include:
How is the radioisotope formed in nature (type of decay)?
Risks associated with the radioisotope
Number of subatomic nucleons present
Stability of the radioisotope
How this radioisotope is used.
Is the radioisotope used as a medical tracer? If yes, for what body part or process? Briefly explain.
(These are just a few suggestions. See if you can find other interesting facts.)
Remember to site your sources in APA style.
Respond to at least two other students.
Contribute to an ongoing discussion by responding to comments made to your posting or to comments made by other students to other postings.
