The application of nuclear technology in the industrial field is extensive and profound, covering multiple aspects, including irradiation processing, material modification, industrial non-destructive testing, etc. The following will provide a detailed explanation of the applications and related standards of nuclear technology in these fields.

1、 The application of nuclear technology in the industrial field

1. Radiation processing
Radiation processing is one of the important applications of nuclear technology in the industrial field, mainly using ionizing radiation such as gamma rays, electron beams, and X-rays to irradiate objects, in order to achieve disinfection, sterilization, insecticidal, and preservation purposes. This processing method has the characteristics of strong penetration, no pollution residue, high efficiency and energy conservation, and is known as a "green" processing technology.
Disinfection and sterilization: Radiation processing is widely used in the disinfection and sterilization of medical and health products, drugs, food, biological products, etc. Radiation treatment can effectively kill microorganisms in the product and extend its shelf life.
Food preservation: The use of irradiation technology can delay the physiological processes of food (such as germination and ripening), inhibit the growth of microorganisms, and thus achieve the purpose of preservation. This method is of great significance for extending the shelf life of food and improving food quality.



2. Material modification
Nuclear technology also has important applications in material modification, mainly by changing the physical and chemical properties of polymer materials through radiation crosslinking, radiation cracking, and other methods to enhance their application value.
Radiation crosslinking: Under the action of ionizing radiation, polymer chains form a three-dimensional network structure by generating bridge bonds between them through free radicals or ions. This polymer with a network structure has properties such as being insoluble in solvents and not easily melted, making it suitable for fields such as wires and cables, heat shrink materials, etc.
Radiation cracking: Radiation cracking is the process of breaking the main chain of a polymer under the action of ionizing radiation. By irradiation cracking, the molecular weight of polymers can be reduced, their solubility and other properties can be altered, giving them new uses.
3. Industrial non-destructive testing
X-ray and gamma rays in nuclear technology are also widely used in the field of industrial non-destructive testing, such as industrial CT testing. These technologies can penetrate the surface of objects, detect the internal structure and defects of objects, and provide important means for product quality control.
Quality inspection: can be used for defect detection in casting and welding processes to ensure product quality meets standards.
Measuring thickness: can be used for online, real-time, non-contact thickness measurement to improve production efficiency.
Item inspection: used at airports, stations, customs and other places to conduct safety checks on luggage, goods, etc., to ensure public safety.

2、 The standards of nuclear technology in the industrial field

The application of nuclear technology in the industrial field needs to follow a series of standards and regulations to ensure the safety and effectiveness of the technology. These standards are usually formulated and published by national or international standardization organizations, covering multiple aspects such as equipment standards, operating procedures, radiation protection standards, etc.
Equipment standard: specifies the performance and safety requirements of irradiation processing equipment, non-destructive testing equipment, etc., to ensure that the equipment can meet technical requirements during use.
Operating standards: Standardize the operating steps, parameter settings, etc. of irradiation processing, material modification, non-destructive testing, etc. to ensure the safety and effectiveness of the operating process.
Radiation protection standards: To protect and control the radiation that may be generated during irradiation processing, non-destructive testing, and other processes, ensuring the safety of workers and the public.
It should be noted that with the continuous development of nuclear technology and the expansion of application fields, relevant standards and specifications are also constantly being improved and updated. Therefore, in practical application, it is necessary to pay close attention to the latest developments of relevant standards to ensure the compliance and progressiveness of technology.

Nuclear technology has been widely and deeply applied in the industrial field, covering multiple aspects such as irradiation processing, material modification, and industrial non-destructive testing. These applications need to follow a series of standards and specifications to ensure the security and effectiveness of the technology.
