Used as a neutron absorber in nuclear reactors due to its high neutron capture cross-section, particularly effective in controlling neutron flux. Employed in radiation shielding and neutron detection systems where isotopic enrichment enhances performance. Also applied in specialized research involving neutron capture therapy for cancer treatment, where precise targeting benefits from the enriched 11B isotope. Additionally serves as a tracer in geochemical and environmental studies to monitor boron behavior with high isotopic specificity.
