What are the differences in neutron absorption between metals for nuclear facility outdoor sculptures?

Neutron absorption is a critical factor when selecting metals for outdoor sculptures in nuclear facilities, as these structures must balance artistic design with functional radiation shielding. Different metals exhibit varying neutron absorption capabilities due to their atomic structures and nuclear properties. For instance, boron-doped stainless steel is highly effective due to boron's high neutron capture cross-section, while aluminum and copper offer moderate absorption. In contrast, lead, though excellent for gamma radiation shielding, has relatively low neutron absorption efficiency. Understanding these differences ensures sculptures meet safety standards without compromising aesthetic value. Factors like material durability, corrosion resistance, and environmental conditions also influence metal selection for such specialized artworks.
