Electron linear accelerator industrial CT radiation safety technical specification

 

I. Introduction

 

With the rapid development of modern science and technology and industry, the industrial CT (Computed Tomography) technology of electron linear accelerator, as an efficient and non-destructive testing means, plays an increasingly important role in the fields of material testing, product quality control, safety assessment and so on. However, while producing high-energy X-rays, electron linAC also brings the problem of radiation safety. In order to protect the health and safety of the staff and the public, and ensure the normal operation of electron linear accelerator industrial CT, this paper will comprehensively discuss the radiation safety technical specifications of electron linear accelerator industrial CT.

Second, the importance of electron linear accelerator industrial CT radiation safety

 

Electron linear accelerator Industrial CT scans the object by emitting high-energy X-rays, and then uses the computer to process the image to obtain the internal structure information of the object. However, X-ray has strong penetrating power and ionization ability, which has certain harm to human body. Therefore, in the use of electronic linear accelerator industrial CT, it is necessary to strictly follow the radiation safety technical specifications to ensure that the radiation dose is controlled within the safe range to avoid unnecessary injury to the staff and the public.

 

Third, electronic linear accelerator industrial CT radiation safety technical specifications

 

Equipment requirements
 

(1) Electronic linear accelerator industrial CT equipment should meet the relevant national standards and regulations, with complete radiation protection and safety facilities.

 

(2) The equipment should be equipped with a high-precision radiation dose monitoring device to monitor the dose and distribution of X-rays in real time.

 

(3) The equipment should have an automatic control system, which can automatically adjust the X-ray dose and scanning parameters according to the actual situation to ensure that the radiation dose is within the safe range.

 

Operator requirement

(1) The operator should have the corresponding professional knowledge and operational skills, familiar with the working principle and operating process of electronic linear accelerator industrial CT.

 

(2) Operators should receive regular radiation safety training, understand the hazards of radiation and protective measures, and master emergency treatment methods.

 

(3) The operator shall strictly abide by the operating procedures to ensure that protective equipment is correctly worn during the operation to avoid unnecessary radiation exposure.

 

Radiation protection requirements

(1) Reasonable radiation protection barriers should be set up in the workplace to reduce the leakage and scattering of X-rays.

 

(2) Workers should wear protective equipment that meets the requirements, such as protective clothing, protective glasses, protective gloves, etc., to reduce radiation damage to the body.

 

(3) During the operation of the equipment, non-staff should be restricted from entering the work area to ensure their safety.

 

Radiation monitoring and recording requirements
 

(1) The radiation dose of electronic linear accelerator industrial CT equipment should be regularly monitored to ensure that the equipment meets radiation safety standards under normal operation.

 

(2) A complete radiation dose monitoring record should be established to record the radiation dose, operator, scan object and other information of each scan for traceability and query.

 

(3) For the equipment whose radiation dose exceeds the safe range, it should be stopped immediately and repaired and maintained to ensure that the equipment is restored to normal operation before being put into use.

 

Emergency handling requirement
 

(1) A detailed emergency response plan should be formulated to clarify the response measures and disposal procedures in the event of a radiation accident.

 

(2) In the event of a radiation accident, emergency procedures should be immediately initiated, effective measures should be taken to reduce radiation damage, and timely report to relevant departments and personnel.

 

(3) Persons exposed to radiation injuries shall be provided with timely medical treatment and rehabilitation measures to ensure their health and safety.

 

Fourth, electronic linear accelerator industrial CT radiation safety management suggestions

 

Strengthen radiation safety publicity and education, and raise the awareness and prevention awareness of radiation hazards among workers and the public.

 

Establish a sound radiation safety management system and operating procedures to ensure the safe operation of electronic linear accelerator industrial CT.

 

Regular inspection and maintenance of electronic linear accelerator industrial CT equipment to ensure the normal operation and radiation safety performance of the equipment.

 

Strengthen communication and collaboration with relevant departments and institutions to jointly promote the development and application of electronic linear accelerator industrial CT radiation safety technology.

 

V. Conclusion

 

As an efficient non-destructive detection method, industrial CT of electron linear accelerator has a wide application prospect in modern industry. However, the radiation safety problem brought by it can not be ignored. Through the formulation and implementation of strict CT radiation safety technical specifications for electron linear accelerator industry, strengthening radiation safety management and emergency treatment measures, can effectively protect the health and safety of staff and the public, and promote the healthy development of CT technology for electron linear accelerator industry.
