职业卫生预评价中X射线机的电离辐射剂量估算和评价方法

Dosage estimation and evaluation method of ionizing radiation of X-ray machine in the pre-assessment of occupational health

X射线成像是先进检测技术,在职业卫生评价和环境影响评价中经常有包含X射线成像技术的新建和改扩建项目,涉及到X射线机作业场所的电离辐射防护措施分析与评价。以450kV X射线机为例进行职业卫生预评价,总结了评价中关键的问题,归纳了X射线电离辐射剂量评估公式和参数转换方法,为X射线机相关的职业卫生评价和环境影响评价提供参考。

[Objective]X-ray imaging is an advanced testing technology. There are many construction projects which includes X-ray imaging technique in the occupational health assessment and environmental impact assessment. Their assessment involves protection measurement analysis and evaluation against ionizing radiation in X-ray workplace. The pre-assessment of occupational health has been done based on a 450 kV X-ray machine in this paper. The X-ray ionizing radiation dose assessment formula and parameters conversion methods are summarized,and the pivotal problems in the pre-assessment of occupational health are summed up,wishing to provide references for the occupational health assessment and environmental impact assessment related to a X-ray machine.
