Question
- A. They enhance the radiation emitted
- B. They absorb radiation effectively
- C. They are lightweight and easy to carry
- D. They allow radiation to pass through
Answer
The correct answer is B: They absorb radiation effectively.
Explanation
The correct answer is B: They absorb radiation effectively. This supports the learning objective "Explain why tongs, lead-lined containers and protective screens reduce radiation exposure." in Radioactive contamination because it uses the correct atomic and nuclear radiation relationship for Atoms and nuclear radiation. The other options are less suitable because they do not match the required Radioactive contamination idea: They enhance the radiation emitted; They are lightweight and easy to carry; They allow radiation to pass through.
Common mistake
Misunderstanding Radiation Shielding
Students often think that using tongs or lead-lined containers completely eliminates radiation exposure.
Emphasize that while these tools reduce exposure, they do not eliminate it entirely; proper distance and time management are also crucial.
