Exam-style question
Try this first
Explain how the intensity of gamma radiation changes as the distance from the source increases, using the inverse-square law.
Model answer
What a good answer should say
- As the distance from the gamma radiation source increases, the intensity decreases according to the inverse-square law, which states that intensity is inversely proportional to the square of the distance from the source.
Explanation
Why this works
This question assesses understanding of the inverse-square law in relation to gamma radiation intensity. A strong answer demonstrates knowledge of how distance affects intensity and the mathematical relationship involved.
