Frontier Technology Corporation has extensive experience in neutron radiation shielding, offering custom-built neutron shielding walls that provide reliable, much-needed protection from harmful radiation.
The Dangers of Neutron Radiation
Because neutron radiation presents so many inherent dangers, top-of-the-line neutron shielding protection is critical. Neutrons have neither a positive nor a negative charge, resulting in a wide range of energy and mass levels that must be blocked. 中子辐射危险, 因此, must be handled with the utmost care and attention to detail, whether dealing with nuclear power facilities, 医用x射线系统, 放射性同位素的项目, or particle accelerator work. Hazardous rays can cause serious and long-lasting physical harm to the people exposed to them, and structural material and environments can also be damaged beyond repair by radioactive waves. Electronic devices and photographic film, 特别是, are a couple of the more sensitive mediums that can be easily damaged.

为了hg0086体育的防护墙, we make use of materials composed of low-atomic-number elements, as they have a high probability of forming cross-sections that will interact with the neutrons. 密集的材料, 比如铅, are less effective in blocking radiation because the neutrons are uncharged and can easily pass through the dense material. Hydrogen and hydrogen-based materials are preferable for neutron shielding because compounds with a high concentration of hydrogen atoms — such as water — act as reliable barriers and provide inexpensive shielding. 然而, neutron radiation shielding is most reliable when it incorporates both high- and low-atomic-number elements, as low-density materials alone can emit gamma rays when blocking neutrons.
Water-extended polyester (WEP) 树脂容易制备, 含水量高吗, 耐火, and has a mechanical strength between those of wood and concrete. Unsaturated polyester resins readily emulsify with water; WEP’s hydrogen content compares to that of water.
Frontier’s WEP material is highly effective for all custom shielding wall needs, and can be used across a range of industries. Our shielding helps protect personnel in harsh environments, such as those within the nuclear, 健康物理学, 国防, 实验室, 以及包装行业. Along with the WEP inner material, our custom shielding walls include 不锈钢 outer materials and can be constructed to have up to 12 inches in neutron shielding thickness, 高达8英尺, 宽度可达6英尺. They also include isotope pass-through ports. We can also fill customer-designed and supplied neutron shielding walls with WEP inner material.
Our production volumes range from prototypes through production quantities with lead times typically around eight to fourteen weeks. Void volume and meter testing services are included. National Institute of Standards and Technology traceability, as well as our own quality assurance manual, help to guarantee wall quality. Additional services include documentation, 集成, 项目管理, 逆向工程, 技术支持.
Our shielding walls meet a range of industry standards, including 10CFR50附录B, IAEA Special Form Certification, U.S. Department of 运输 (USDOT) and U.S. 核 Regulatory Commission (USNRC) regulations, NIST-traceable requirements, and ISO 2919.
