Radiation safety technical specifications for industrial CT of electronic linear accelerators

1、 Introduction

With the rapid development of modern industrial technology, Computed Tomography (CT), as an advanced non-destructive testing technology, has been widely used in fields such as aerospace, mechanical manufacturing, and materials science. However, the X-rays generated by electron linear accelerators have potential radiation hazards to human health and the environment. Therefore, developing and implementing strict radiation safety technical specifications for industrial CT of electronic linear accelerators is of great significance for ensuring personnel safety and preventing environmental pollution.



This article aims to explore the content and requirements of the radiation safety technical specifications for industrial CT of electronic linear accelerators, including equipment design, radiation protection, safety management, personnel training, etc., in order to provide reference and guidance for relevant enterprises and units.

2、 Equipment design requirements

Equipment structure: Industrial CT equipment for electronic linear accelerators should have good structural design and stability to ensure that structural deformation or damage will not occur under normal working conditions. At the same time, the equipment should be equipped with comprehensive safety interlocking devices to prevent radiation leakage caused by misoperation or unexpected situations.

Ray source: Ray source is the core component of industrial CT equipment for electron linear accelerators, and its performance directly affects the radiation safety of the equipment. The radiation source should meet the requirements of relevant national standards, have stable and reliable output performance, and be equipped with automatic detection and adjustment devices to ensure the accuracy and safety of the radiation output.

Detection system: The detection system is responsible for receiving signals from rays passing through objects and converting them into image data. The detection system should have the characteristics of high sensitivity, high resolution, and fast response to ensure imaging quality and detection efficiency. At the same time, the detection system should have the ability to resist radiation interference and prevent the impact of external radiation on image quality.


3、 Radiation protection requirements

Radiation shielding: Industrial CT equipment for electronic linear accelerators should be equipped with effective radiation shielding devices to limit the X-rays generated by the equipment within a safe range. Radiation shielding devices should use appropriate materials and structures to ensure effective absorption and shielding of radiation.

Protective facilities: Obvious radiation warning signs and protective facilities, such as protective doors and windows, should be installed around the equipment. Protective facilities should have good sealing and durability to prevent radiation leakage and personnel from entering the radiation area.

Radiation monitoring: A radiation monitoring system should be established to monitor and record the radiation levels around the equipment in real-time. Monitoring data should be regularly analyzed and evaluated in order to promptly detect and handle abnormal situations.

4、 Security management requirements

Safety system: Enterprises should establish and improve the safety management system for industrial CT equipment of electronic linear accelerators, clarify the management requirements and responsibilities for the use, maintenance, repair, and scrapping of equipment in various aspects.

Operating procedures: Equipment operators should strictly follow the operating procedures to ensure that the equipment operates in the correct operating state. At the same time, operators should receive regular training and assessments to improve their operational skills and safety awareness.

Emergency plan: Enterprises should develop an emergency plan for radiation accidents of industrial CT equipment for electronic linear accelerators, clarifying emergency organization, rescue measures, and disposal procedures. Emergency plans should be regularly rehearsed and evaluated to ensure their effectiveness and feasibility.

5、 Personnel training requirements

Training content: Equipment operators should receive training on radiation safety knowledge, equipment operation skills, emergency plans, and other aspects. The training content should be targeted and practical to enhance the safety awareness and operational skills of operators.

Training methods: Training methods can take various forms such as classroom lectures, practical operations, and case analysis. At the same time, professional personnel can be invited to provide on-site guidance and demonstrations to improve training effectiveness.

Training effectiveness evaluation: After the training is completed, operators should be assessed and evaluated to ensure that they have the ability to independently operate equipment and safety awareness. For unqualified operators, training and assessment should be conducted again.

6、 Summary and Outlook

The radiation safety technical specifications for industrial CT of electronic linear accelerators are important measures to ensure personnel safety and prevent environmental pollution. By establishing and implementing strict regulations, the radiation risk generated during equipment use can be effectively reduced, and the application level and safety of industrial CT technology can be improved. In the future, with the continuous progress of technology and the continuous development of industrial CT technology, we should further improve and standardize the radiation safety technical specifications for electronic linear accelerators in industrial CT, providing more solid safety guarantees for the widespread application of industrial CT technology.
