The radiations from a naturally occurring radioactive substance, as seen after deflection by a magnetic field in one direction, are:
Correct answer: D. Either Alpha or Beta rays
- A. Definitely Alpha-rays
- B. Definitely Beta-rays
- C. Both Alpha and Beta rays
- D. Either Alpha or Beta rays
Explanation
Both alpha and beta particles are affected due to the magnetic field and so both rays may be produced, but not simultaneously.

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.
