Which term describes materials that become radioactive after exposure to neutron radiation in a reactor?

• A. Fission products
• B. Decay products
• C. Contaminants
• D. Activated Corrosion Products

Answer: (D)

In a reactor, materials can become radioactive when stable nuclei capture neutrons and turn into radioactive isotopes. The term that best fits this situation is activated corrosion products, which are the corrosion-derived materials in the reactor environment that have been neutron-activated and thus become radioactive. This distinguishes them from fission products (radionuclides produced by fuel fission), decay products (radionuclides formed by decay of other radionuclides), and contaminants (general impurities without specifying activation). Activated corrosion products are a common source of radiation in the reactor cooling system and influence shielding, filtration, and cleanup considerations.
