What is the unit of activity in nuclear physics?.
- A.Becquerel
- B.Gray
- C.Sievert
- D.Coulomb
Model answer
What a good answer should say
- Becquerel
Explanation
Why this works
The evidence shows that activity is measured in becquerels (Bq), which indicates the number of decay events per second. This implies that activity quantifies the rate of radioactive decay, making it a crucial parameter in nuclear contexts.
Therefore, the correct answer is becquerel.
