alleryArtificial (induced) radioactivity was first discovered by
AHenri Becquerel alone
BIrene Curie and F. Joliot
CErnest Rutherford alone
DOtto Hahn and Strasman
Answer & Solution
Correct answer: B. Irene Curie and F. Joliot
1. Inducing radioactivity in light elements by bombardment is artificial radioactivity.
2. It was discovered by Irene Curie and F. Joliot in 1934.
3. Becquerel discovered natural radioactivity, not the artificial kind.
4. Hahn and Strasman discovered nuclear fission, a different finding.
