Question
- A. Different types of radiation emitted
- B. Varying geological materials
- C. Altitude differences
- D. Proximity to nuclear facilities
Answer
The correct answer is B: Varying geological materials.
Explanation
The correct answer is B: Varying geological materials. This supports the learning objective "Compare natural and artificial sources of background radiation using data." in Background radiation 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 Background radiation idea: Different types of radiation emitted; Altitude differences; Proximity to nuclear facilities.
Common mistake
Confusing Sources of Background Radiation
Students often confuse natural sources of background radiation, such as cosmic rays and radon gas, with artificial sources like medical uses and nuclear power.
To fix this, students should create a clear list categorizing sources of background radiation into natural and artificial, ensuring they understand examples of each.
