Hazards and uses of radioactive emissions and of background radiation
Question
- A. The color of the isotope.
- B. The type of radiation it emits and its half-life.
- C. The cost of the isotope.
- D. The location of the isotope's discovery.
Answer
The correct answer is B: The type of radiation it emits and its half-life..
Explanation
The correct answer is B: The type of radiation it emits and its half-life.. This supports the learning objective "Explain why a very long half-life can increase long-term hazard." 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: The color of the isotope.; The cost of the isotope.; The location of the isotope's discovery..
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.
