Consider a radioactive material of half-life 1 minute. If one of the nuclei decays now, the next one will decay:
Correct answer: B. After any time
- A. After one-minute
- B. After any time
- C. After two minutes
- D. After 1/2 minute
Explanation
Radioactive decay is a spontaneous phenomenon. It can decay anytime.

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.
