What is a “half-life” and why is it important to know the half-life of a radioisotope? List a few applications of how scientists make use of having this knowledge. Why would it be so important to know the half-lives of radioisotopes when it comes to medical applications?

Chemistry and measurement

Assignment:

Address the questions listed below fully with complete sentences. Make sure to put it in your own words, paraphrasing and summarizing. Only use quotes when necessary, citing all sources used. Do make sure to apply the appropriate in-text citations when necessary. Make sure to review the Instructions page for this assignment as well.

⦁ Create an “Introduction” section. In the first paragraph of this introduction, briefly describe the purpose of this assignment.

Also conduct some research and write a brief paragraph(s) that addresses each of the following questions:

⦁ What is natural radioactivity? Speak to the different types of radiation that an unstable nucleus may emit, and the different types of radiation involved.

⦁ Why is it important to be able to write a balanced nuclear equation for radioactive decay? Go into some of the specifics of what is involved in writing an equation.

⦁ What is a “half-life” and why is it important to know the half-life of a radioisotope? List a few applications of how scientists make use of having this knowledge. Why would it be so important to know the half-lives of radioisotopes when it comes to medical applications?

⦁ Briefly describe how we can make use our knowledge of radioactivity in medicine. Speak about the characteristics of the radioisotopes used in these types of applications.

What might they have in common? What process(es) do we use to detect these radioisotopes?
