硼-10

B-10


產品介紹 Product introduction

天然硼元素有兩種穩定同位素,即10B和11B,相對豐度分別為19.78%和80.22%。10B質子數為5,中子數為5。10B具有對中子高吸收的獨特特性,對熱中子的吸收截面為3837靶,是高效的熱中子吸收劑,在核電站中它是安全和控制系統中所不可缺少的,正是由于10B同位素的這種特性,使得10B同位素的相關產品廣泛應用到了防護用品、核工業等領域。

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.

產品用途 Application

10B在核工業、醫學及科學技術領域具有廣泛的用途。在防護用品中,富集10B的同位素主要用于防護中子彈,比如核防護服、中子槍防護服等;在核工業中,10B是核反應中屏蔽輻射和核反應強度控制的理想材料;在現代醫療領域中,硼中子俘獲治療癌癥(NCT)是一種新的放療方法,中子主要與NCT藥物中的靶核素(10B同位素)發生核反應,產生對癌細胞起殺傷作用的次級輻射及反沖粒子。

 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 nuclear industry, 10B is an ideal material for shielding radiation and controlling the intensity of nuclear reactions. In the field of modern medicine, boron neutron capture therapy method is a new radiotherapy method for cancer treatment based on the ability of 10for capturing thermal neutrons, the neutron mainly reacts with the target nuclide (10B isotope) in NCT drugs to produce secondary radiation and recoil particles that can kill cancer cells.
