摘要
目的了解典型稀土矿职业人员辐射认知程度。方法通过现场了解及文献调研,咨询专业人士,设计辐射认知调查表,采用随机整群抽样方法,对职业人员进行问卷调查,录入数据并分析结果。结果稀土矿职业人员辐射认知总体水平较低,对辐射危害知晓率、内外照射知晓率及其主要包括射线种类得分,粉尘较低组均优于粉尘较高组(P<0.05),对辐射危害认知得分,粉尘较低组略优于粉尘较高组(0.05<P<0.1);年龄、学历、获取辐射相关知识途径、内外照射对应防护措施得分,均尚不能认为两组中有差别。结论典型伴生稀土矿职业人群辐射认知整体水平较低,尤其是接尘浓度较高组,应加强培训与管理。
Objective To investigate the radiation awareness of occupational staff in a typical rare earth ore.Method A questionnaire for the radiation awareness was designed through field observation,literature query and consulting professionals.And the survey was conducted among the occupational staff via the random cluster sampling method.Results The overall level of radiation awareness among occupational staff was generally poor.The cognitive scores of ionizing radiation,internal and external exposure and their main types were higher in the lower dust group than those in the higher dust group(P<0.05),and the cognitive scores on radiation hazard in the lower dust group were also slightly higher than those of the higher dust group(0.05<P<0.1).However,there were no statistically significant of age,education level,the pathways of obtaining the radiation-related knowledge,and the knowledge of preventive measures for internal and external radiation between the two groups.Conclusion The overall radiation awareness of occupational staff in the typical rare earth ores should be enhanced,especially for the staff working in the high dust and aerosol concentration environment.The protection awareness was insufficient and radiation training should be strengthened.
