Boron-10 B-10 Stable Isotope Materials Nuclear Safety Materials Product introduction Natural boron has two kinds of stable isotopes, 10B and 11B, with relative abundance of 19.78% and 80.22%, respectively. 10B has five protons and five neutrons.10B has the characteristics of high absorption for neutron, the absorption cross section for thermal neutron is 3837b, it is highly effective absorber for thermal neutron, it is indispensable in safety and control system of nuclear power station. Due to the characteristics of 10B isotopes, the related products of 10B isotopes are widely used in the protective equipment, nuclear industry and other fields. Application 10B isotopes are widely used in the nuclear industry, medicine and science and technology. In protective equipment, 10B isotopes are mainly used for neutron bomb protection, such as nuclear protective clothing, neutron gun protective clothing, etc. In the nuclea…
