Industrial Application of Nuclear Technology

Nuclear science and technology improve our lives in many ways and in many different areas.  It makes our food safer; it improves the quality of tools, gauges, and machines; it diagnoses abnormalities of the metabolism and treats cancers; it powers space travel; and it offers one of the cleanest and most environmentally-friendly ways of generating electricity.

核科学和技术在许多方面和不同领域改善了我们的生活。它使我们的食物更安全;它提高了工具、仪表和机器的质量;它不仅能诊断新陈代谢的异常,还能治疗癌症;它为太空旅行提供动力;它也可以提供一种最清洁和最环保的发电方式。

Non Destructive Testing

It is essential to test materials, products, structures or buildings without altering their properties or affecting their usefulness. X-rays and gamma rays are used in industrial radiography to make images of the inside of solid products, as a means of nondestructive testing (NDT) and inspection. NDT radiography is used in the petroleum, chemical and nuclear industries, as well as on assembly lines to test consumer goods.

Car wheels, receive a quality check of this type before leaving the factory.Pipelines are inspected both during installation and maintenance to ensure that welds remain intact.Adding a gamma tracer to a gas or liquid in a closed system makes it possible to find a hole in a tube.Adding a tracer to the surface of the component of a motor makes it possible to measure wear by measuring the activity of the lubricating oil.

在不改变材料、产品、结构或建筑物的特性,不影响其用途的情况下对其进行测试是非常重要的。X射线和伽玛射线常用于工业射线照相技术,作为无损检测(NDT)和检验的手段,其对固体产品的内部进行成像。无损检测射线照相技术常见于石油、化工和核工业的应用,也常用于测试消费品的装配线。
•车轮在出厂前都会接受此类质量检查。
•管道在安装和维护期间进行检查,以确保焊完好无损。
•在封闭系统中的气体或液体中添加伽马示踪剂,使其可以在管道中找到可能的泄漏点。 •在电机部件表面添加示踪剂,可以通过测量润滑油的活性来测量磨损。

Ensuring Product Quality

Nucleonic gauges – instruments that use a radioisotope source to measure materials and products – are used to ensure optimum coating thicknesses, such as metal-coating.Moisture gauges are used in construction materials (asphalt and concrete), glass, mineral processing, chemicals and food.
Radioisotope gauges are used to measure mass per unit of area n manufacturing aluminum foil, paper and steel plate.

•核测厚仪—使用放射性同位素源测量材料和产品的仪器—用于确保最佳涂层厚度,如金属涂层。             
•利用核技术原理制造的湿度计可用于监测建筑材料(沥青和混凝土)、玻璃、矿物加工、化学品和食品。
•在制造铝箔、纸张和钢板时,放射性同位素测量仪可用来测量单位面积的质量。

Enhancing Material Quality

Radiation is is used to create high-performance polymeric materials.Radiation can cause cross-linking of some molecules to form giant molecules which have higher heat, chemical and mechanical resistance. This helps harden plastics.The wire and cable industry also uses cross-linking to strengthen the insulation of wires and cables and make them more heat resistant.Radiation vulcanisation of natural rubber latex (RVNRL) imparts strength and elasticity, making it ideal for the production of surgical gloves (standard and allergy-free), catheters, balloons used in cardiac procedures and even automobile tires.

•射线可用于制造高性能聚合物材料
•射线可导致一些分子交联,形成具有更高热阻、化学阻力和机械阻力的大分子。这有助于硬化塑料
•电线电缆行业还使用交联技术加强电线电缆的绝缘,使其更耐热
•天然橡胶乳胶(RVNRL)的辐射硫化可以实现更好的强度和弹性,使其成为生产外科手套(标准和无过敏)、导管、心脏手术用气球甚至汽车轮胎的理想材料.

Electrostatic control – To avoid the build-up of static electricity in production of paper, plastics, synthetic textiles, etc., a ribbon-shaped source of the alpha emitter 241Am can be placed close to the material at the end of the production line. The source ionizes the air to remove electric charges on the material.Radioactive tracers – Since radioactive isotopes behave, chemically, mostly like the inactive element, the behavior of a certain chemical substance can be followed by tracing the radioactivity.Oil and Gas Exploration- Nuclear well logging is used to help predict the commercial viability of new or existing wells. The technology involves the use of a neutron or gamma-ray source and a radiation detector which are lowered into boreholes to determine the properties of the surrounding rock such as porosity and lithography.

静电控制—为了避免在纸张、塑料、合成纺织品等生产过程中产生静电,可以在生产线末端靠近材料的地方放置一个带状的α衰变源241Am电源。放射源使空气电离以除去物质上的电荷。 放射性示踪剂—由于放射性同位素在化学上的行为与非活性元素基本相同,因此可以通过追踪放射性来跟踪某一化学物质的行为
油气勘探—核测井用于帮助预测新井或现有井的商业可行性。这项技术包括使用中子或伽马射线源和辐射探测器,这些探测器被放进钻孔中,以确定围岩的特性,如孔隙率和光刻。
