Radiographic inspection room radiation protection design method

Abstract

The invention relates to a radiographic inspection room radiation protection design method. Monte-Carlo software is employed to carry out modeling and protection effect simulation, the protection effect of a main structure can be evaluated, the protection effect of detailed structures can also be evaluated, and the evaluation accuracy of the whole radiation protection effect of the radiographic inspection room is improved; in dependence on the simulation analysis result, parameters of the main structure and the detailed structures are corrected repeatedly, and the corrected parameters are simulated again. The structure of the radiographic inspection room is optimized, ray leakage problems are avoided, and therefore the risk that the radiographic inspection room needs to be modified after being built is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a design method of a radiation detection room, in particular to a radiation protection design method of a radiation detection room. Background technique [0002] Radiographic inspection technology is a non-destructive inspection technology that uses X-rays to detect internal information of objects. This technology is widely used in industry and medical industry. The X-rays in the radiation detection room are harmful to the surrounding environment and the human body, and special protective structures need to be set up for radiation protection during use. [0003] The design of the existing radiographic inspection room includes the following steps: [0004] 1) Determine the type and intensity of the radiation source; [0005] 2) According to the parameters of the radiation source, use empirical formulas or search the technical manual to determine the main protection parameters of the detection room; [0006] 3) Design the stru...

AI Technical Summary

Problems solved by technology

[0009] 1) The radiation protection structure calculated by the formula or searched in the technical manual is not accurate enough, and there is a certain difference with the actual situation

[0010] 2) Theoretical calculation or look-up table can only get the main structure of the protection, such as the thickness of the main protection wall, the thickness of the side wall, and other parameters

For the details of the protective structure, such as trenches, gaps, etc., precise design cannot be made, and there is a risk of radiation leakage

[0011] 3) The theoretical evaluation of the protective effect of the testing room is only based on theoretical formulas, and the details cannot be evaluated, and the evaluation is not accurate enough. There is a greater risk of rectification after the testing room is completed
