同位素与辐射技术是核科学技术向非核科学领域扩展和渗透而形成的一门交叉技术．它分为七项应用技术．同位素仪表、核医学、同位素示踪、辐射加工、固体材料辐射改性、核分析技术和核农业．同位素仪表是不接触被测物的控制手段，它是核技术应用中经济效益最大的一个方面．同位素示踪，其示踪剂不改变所加体系的原有状态和特性，探测灵敏度极高甚至可做到对原子数目一个个地进行计量．利用辐射可对物质或材料进行改性和对医疗用品进行消毒．核分折技术灵敏度高，准确性好，又不损坏样品，可作痕量或超痕量元素分析．总之，同位素与辐射技术具有其他技术不可替代的优点，已经而且将为人类带来越来越显著的经济效益和社会效益，是一门应用广泛的新技术．
Isotopes and radiation technology is a cross-cutting technology formed by the expansion and infiltration of nuclear science and technology into non-nuclear science. It is divided into seven application techniques. Isotopic Instrumentation, Nuclear Medicine, Isotope Tracing, Radiation Processing, Radiation Modification of Solid Materials, Nuclear Techniques and Nuclear Agriculture. Isotope instrument is not in contact with the measured object control means, it is the economic benefits of nuclear technology applications one aspect. Isotopic tracer, the tracer does not change the original state and characteristics of the added system, high detection sensitivity can even be done to measure the number of atoms one by one. Radiation can be used to modify substances and materials and sterilize medical supplies. Nuclear analysis of high sensitivity, accuracy, without damage to the sample can be used for trace or ultra-trace elements analysis. In short, the isotope and radiation technology has the irreplaceable advantages of other technologies, has been and will bring more significant economic and social benefits to human beings, is a widely used new technology.
