Question
What are the implications of using a radioactive isotope with a very long half-life in medical applications?
Answer
Using a radioactive isotope with a very long half-life in medical applications can lead to prolonged radiation exposure for patients, which may increase the risk of radiation-related health issues. Therefore, such isotopes are typically avoided in favor of those with shorter half-lives that limit patient exposure.
Explanation
This question assesses the ability to apply knowledge of half-lives to real-world scenarios in medicine. A strong answer reflects an understanding of the balance between the usefulness of the isotope and the associated risks.
Common mistake
Long Half-Life Misunderstanding
Students often confuse a long half-life with a low hazard, thinking it means less risk over time.
Emphasize that a long half-life means the radioactive material remains active and potentially hazardous for a longer duration, increasing long-term risk.
