Question
What are the consequences of using a medical tracer with a very long half-life?
Answer
Using a medical tracer with a very long half-life can increase the long-term hazard to the patient due to prolonged exposure to radiation. This can lead to potential health risks, including an increased chance of cancer.
Explanation
This question assesses the ability to analyze the implications of half-life in medical applications. It requires an understanding of the risks associated with prolonged radiation exposure.
Common mistake
Misunderstanding Half-Lives
Students often confuse the concept of half-life with the total time a radioactive isotope is active, thinking it refers to the entire duration of radioactivity rather than the time taken for half of the radioactive atoms to decay.
To fix this, students should focus on understanding that half-life is a specific time period during which half of the radioactive material decays, and that isotopes can remain active for multiple half-lives.
