Hazards and uses of radioactive emissions and of background radiation
Question
- A. To ensure isotopes are colorful.
- B. To maximize the effectiveness while minimizing health risks.
- C. To reduce the cost of isotopes.
- D. To increase the shelf life of isotopes.
Answer
The correct answer is B: To maximize the effectiveness while minimizing health risks..
Explanation
The correct answer is B: To maximize the effectiveness while minimizing health risks.. This supports the learning objective "Evaluate risks and benefits of using radioactive isotopes." 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: To ensure isotopes are colorful.; To reduce the cost of isotopes.; To increase the shelf life of isotopes..
Common mistake
Misunderstanding Risk Evaluation
Students often confuse the risks associated with radioactive isotopes with their benefits, failing to evaluate both aspects together.
To fix this, students should create a table listing the risks and benefits of each radioactive isotope, ensuring they consider both sides before making a conclusion.
