- C. The color of the isotope
- D. The availability of the isotope
Answer
The type of radiation and half-life
Explanation
When choosing a radioactive isotope for medical applications, it is crucial to consider both the type of radiation it emits and its half-life to ensure safety and effectiveness.
Common mistake
Misunderstanding Half-Life Suitability
Students often confuse the concept of half-life with the total duration a radioactive isotope remains active, failing to recognize that a suitable half-life must balance effectiveness and safety in medical or industrial applications.
To fix this, students should focus on understanding that a suitable half-life allows for effective use of the isotope while minimizing exposure risk, ensuring they can explain the importance of both short and long half-lives in different contexts.
