Question

Which of the following is/are example(s) of induced radioactivity reaction?

Consider the following nuclear reactions:

1. ${}_7^{14}N+{}_4^{4}He⟶{}_8^{17}O+{}_1^{1}H$

2. ${}_4^{9}Be+{}_1^{1}H⟶{}_3^{6}Li+{}_2^{4}He$

3. ${}_{12}^{24}Mg+{}_2^{4}He⟶{}_{14}^{27}Si+{}_0^{1}n$

4. ${}_5^{10}B+{}_2^{4}He⟶{}_7^{13}N+{}_0^{1}n$

• A. 3 and 4
• B. 1 and 2
• C. 1, 3 and 4
• D. 1, 2, 3 and 4

Answer 1

The correct option is D 1, 2, 3 and 4

Induced Radioactivity:
Radioactivity that is created when stable substances are bombarded by ionizing radiation. For example, the stable isotope cobalt-59 becomes the radioactive isotope cobalt-60 under neutron bombardment.

Here, in all four reactions, we are using some particles for bombardment and to make radioactive element so they all are induced radioactive reactions.
