前沿科技公司(FTC)是世界上主要的hg0086体育-252 (Cf-252)中子源供应商之一, 一种放射性元素，用于从核电站启动到材料识别的各种应用中. We offer customized neutron sources for oil and gas, nuclear power, and military and defense, among other industries. Our specialties and services span the full lifecycle of californium-252, including its supply, shipping containers, transportation, handling, and fee-free depleted source disposal.
To help you better understand our sources and what we do, hg0086体育编制了以下术语表，以澄清与hg0086体育-252有关的术语, neutron sources, and neutron radiation, including resources for further exploration into each term.
Californium; Californium-252 (Cf-252)
Californium (Cf) 是1950年在伯克利的加州大学辐射实验室发现的一种合成元素吗. 它最初是由氦粒子轰击元素curium而产生的. 由此产生的元素是一种柔软的银白色金属，在高达900°C的温度下保持固体状态. As a solely synthetic element that does not occur in nature, californium has undergone numerous experiments since the 1950s, resulting in 20 characterized isotopes. Located on the bottom row and grouped with other actinide elements, californium has the second-highest mass of all elements on the periodic table.
Californium-252 是一个每分钟释放1.7亿个中子的极高中子发射器吗, making it the most-used californium isotope. Cf-252提供的自发中子辐射使其成为许多应用中有用的中子源, including nuclear reactor startup, oil well logging, and material scanning and identification. Intense radioactivity makes Cf-252 very dangerous to the human body, and handling requires extreme caution.
Neutron Source
A neutron source 是否有任何材料或装置发射的中子足以被中子探测设备探测到. Common neutron sources include radioisotopes such as californium-252, particle accelerators, and nuclear reactors, among others. Neutron sources see broad usage in numerous industries, including medicine, nuclear power, weapons manufacturing, material detection, and petroleum exploration.
Neutron Shielding
(Click to Expand)
Neutron shielding 指为防止中子辐射从放射源向人体传播而专门设计和安装的设备或材料. 由于中子辐射非常危险，使用者必须采取适当的防护措施. 高浓度的氢原子已被证明对中子辐射很有用, 但理想的中子屏蔽包括高原子序数和低原子序数元素的组合，以获得最佳保护. 水延伸聚酯(WEP)为防护设备提供了有效的解决方案, protective wall designs, and more because of its high water content.
Nuclear Start-Up Rods (Nuclear Reactor Rod Assemblies)
Nuclear startup rods initiate the fission process in a fully-fueled nuclear assembly. Beyond standard reactor startup and shutdown, startup rods also help initiate emergency shutdowns, establish reactor and power control, and maintain axial offset control in nuclear power plants. Although the isotopes americium-241, plutonium-238, polonium-210, 镭-226通常与铍结合使用来启动核反应, hg0086体育-252已成为首选的同位素，因为它能够自发发射中子来引发裂变.
Portable Isotopic Neutron Spectroscopy (PINS)
Portable Isotopic Neutron Spectroscopy (PINS) 1992年开发的一项技术是否用于无损检测和识别诸如简易爆炸装置之类的容器中的有害物质, bombs, and missiles. pin技术有助于探测各种爆炸物和危险化学剂. pin系统已经成功地检测到数以万计的有害化学剂, preventing harm to military and law enforcement personnel worldwide.
Prompt Gamma Neutron Activation Analysis (PGNAA)
Prompt Gamma Neutron Activation Analysis (PGNAA) 利用中子来确定给定样品的元素组成和数量. Neutrons are fired at the sample, which can range in size from small to very large, 样品中的元素通过反应产生不同程度的伽马射线. PGNAA技术提供实时测量伽马射线，以确定样品成分. Oil, gas, 混凝土生产经常使用这种技术来检测提取作业所需的材料沉积物.
Radioactivity (AKA Radioactive Decay)
Radioactivity, also known as radioactive decay, is the active disintegration of an unstable atomic nucleus. 可以测量衰变核释放(辐射)的能量，以确定样品中给定元素或元素的放射性. 放射性衰变释放的能量以α、β或γ射线的形式释放出来.
Radiation Dose (AKA Radioactive Dose)
A radiation dose, or radioactive dose, 暴露于辐射源的物质所吸收的电离辐射量是多少. 这个量取决于受影响的物质和辐射源的放射性强度. 重要的是要注意放射性和辐射剂量是不同的东西. Whereas radioactivity refers to the source’s strength, 辐射剂量特指暴露于该辐射的物质(或身体)所吸收的辐射量.
Type-A Radioactive Shipping Containers
Type-A radioactive shipping containers 是否用于向核制造设施和最终用户运送所有放射性物质. 它们可以定制，以满足尺寸需求和必要的屏蔽能力，以安全和充分地保护中子源. 请注意，前沿科技公司的a型放射性容器不能与伽玛源一起使用, 因为它们不含安全运输所需的铅.
