Nuclear power reactors incorporate biological shielding to protect ______________ from radiation hazards?
Show answer Hide answer
Answer: B. Operating personnels
Explanation
Biological shielding in nuclear power plants is installed around the reactor core to protect operating personnel from harmful neutron and gamma radiation. Intense radiation emitted during nuclear fission poses severe health hazards to any human working near the reactor core. Thick concrete and lead shielding barriers absorb penetrating radiation, ensuring safe working environments for plant staff. Nuclear reactors produce high-energy gamma rays and fast neutrons that can damage human biological tissue and DNA. Radiation protection engineering establishes strict dosage limits and safety barriers to safeguard nuclear industry workers. Biological shielding structures are engineered using dense materials capable of attenuating intense fluxes of ionizing radiation.
Fuel elements require physical containment cladding rather than biological shielding, which is specifically designed for human protection. Walls of the reactor provide structural support and pressure containment, whereas biological shielding specifically protects human workers. Option B accurately identifies human operating personnel as the primary biological entities requiring radiation protection shielding.
