How does background radiation affect measurements of radioactive decay?.
- A.It has no effect on measurements.
- B.It can lead to an underestimation of decay rates.
- C.It can lead to an overestimation of decay rates.
- D.It only affects measurements in laboratory settings.
Model answer
What a good answer should say
- It can lead to an overestimation of decay rates.
Explanation
Why this works
The evidence indicates that background radiation contributes to the total count of detected radiation events. This implies that without proper correction for background radiation, measurements of decay rates may be inaccurately high.
Thus, the correct answer is that it can lead to an overestimation of decay rates.
