【摘要】：眼晶体剂量限值的降低,引起了人们对眼晶体剂量监测、评价和防护的关注。通过近期国内外的研究工作,本文从蒙卡计算、基于人体模型或临床实践的实验测量深入调查了铅眼镜的防护效果,强调了铅眼镜对介入手术中职业人员眼晶体防护的重要性。基于铅眼镜防护效果的研究现状,分析了防护效果的影响因素:通过铅眼镜和眼睛间隙的射线,是眼晶体剂量的主要来源;决定铅眼镜防护效果的并不是射线能量、铅当量厚度、镜片面积等因素,而是眼镜结构、佩戴间隙、投照角度、位置布局、人员姿态等几何条件。调研分析铅眼镜防护效果旨在为眼晶体防护研究和临床实践提供参考。
[Abstract]:The decrease of the dose limit of eye lens has attracted the attention of eye lens dose monitoring, evaluation and protection. Through recent research work at home and abroad, this paper investigates the protective effect of lead glasses on the basis of experimental measurements based on human model or clinical practice, and emphasizes the importance of lead glasses in eye lens protection of professional personnel during interventional surgery. Based on the present situation of the research on the protective effect of lead glasses, this paper analyzes the influencing factors of the protective effect: through the lead glasses and the ray of the eye space, it is the main source of the dose of the eye lens, and it is not the ray energy that determines the protective effect of the lead glasses. Lead equivalent thickness, lens area and other factors, but glasses structure, wear gap, projection angle, position layout, personnel posture and other geometric conditions. The purpose of investigation and analysis of the protective effect of lead glasses is to provide reference for the research and clinical practice of ocular lens protection.
