One Becquerel is equal to:
Correct answer: A. One decay per second
- A. One decay per second
- B. Two decay per second
- C. Three decay per second
- D. Four decay per second
Explanation
One Becquerel (Bq) is defined as one decay per second. It's the SI unit of radioactivity, and it measures the rate of radioactive decay.If a radioactive sample has an activity of 1 Bq, it means that one nucleus in that sample decays (emits radiation) every second, on average.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
