A material that does NOT become radioactive after absorbing neutrons is called.
Correct answer: C. Control material
- A. Shielding
- B. Reactor fuel
- C. Control material
- D. Both A and C
Explanation
Those materials that do not become radioactive after absorbing neutrons are called control materials. In order to control the nuclear fission in a reactor suitable neutron absorbing materials are required to be placed in the core region. The control material should be such that it does not become radioactive by the neutron capture. Cadmium has been found to be a good control material Sindh Textbook for Class XII P324

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
