Radioactive activity is affected by:
Correct answer: D. None of the above
- A. Temperature
- B. Pressure
- C. Humidity level
- D. None of the above
Explanation
Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This process is governed by nuclear forces and is not influenced by external environmental factors such as temperature, pressure, or humidity. Therefore, the correct answer is None of the above. The other options are incorrect because they suggest that external conditions, which affect chemical reactions, also affect nuclear reactions, which they do not.

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.
