Hazards and uses of radioactive emissions and of background radiation
Question
- A. Higher radiation levels are always better for treatment
- B. Isotope choice should balance usefulness and exposure risk
- C. All isotopes are equally safe for medical use
- D. Only isotopes with short half-lives are useful
Answer
The correct answer is B: Isotope choice should balance usefulness and exposure risk.
Explanation
The correct answer is B: Isotope choice should balance usefulness and exposure risk. This supports the learning objective "Explain why isotope choice depends on balancing usefulness and exposure risk." in Different half-lives of radioactive isotopes because it uses the correct atomic and nuclear radiation relationship for Hazards and uses of radioactive emissions and of background radiation. The other options are less suitable because they do not match the required Different half-lives of radioactive isotopes idea: Higher radiation levels are always better for treatment; All isotopes are equally safe for medical use; Only isotopes with short half-lives are useful.
Common mistake
Isotope Selection Confusion
Students often confuse the importance of half-life with the type of radiation emitted when choosing isotopes for medical or industrial use.
Emphasize that both the half-life and the radiation type must be considered to ensure the isotope is useful while minimizing exposure risk.
