The decay constant λ of a radioactive sample:
Correct answer: C. Is independent of the age
- A. Decrease as the age of atoms increase
- B. Increase as the age of atoms increase
- C. Is independent of the age
- D. Depends on the nature of activity
Explanation
The decay constant is a property of the radioactive material itself, and it does not change over time. This means that the rate of decay of a radioactive sample will be the same regardless of how old the sample is.

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.
