钢结构X射线检测工作的辐射防护分析

Analysis on Radiation Protection for X-ray Testing of Steel Structures

钢结构因具有施工便利、质量轻、坚固耐用等特点而被广泛应用于建筑市场。钢结构检测工作是确保建筑结构稳定性和安全性的重要环节,应用X射线检测技术可确定钢结构内部的缺陷和各种不良状况,但也由此带来了辐射防护问题。文章阐述了X射线检测技术的原理及产生的放射性污染对人体的危害,以福建省福州市某桥梁改造工程为例,分析了试曝光阶段和曝光探伤阶段的辐射防护,旨在为相关从业人员提供借鉴。

Steel structure is widely used in the construction market because of its convenient construction,light weight,robustness and durability.Steel structure testing is an important link to ensure the stability and safety of building structure.The application of X-ray testing technology can identify internal defects and various adverse conditions of steel structure,but it also brings the problem of radiation protection.This paper expounds the principle of X-ray testing technology and the harm of radioactive pollution to human body.Taking a bridge reconstruction engineering in Fuzhou City,Fujian Province as an example,it analyzes the radiation protection in the trial exposure stage and the exposure crack detection stage,aiming to provide reference for relevant practitioners.
