【摘要】：目的：通过对苏州市2006年至2011年部分放射工作人员的职业健康体检资料、放射防护培训资料以及部分放射工作人员2011年和2012年个人剂量监测结果的分析，观察职业照射对放射人员的身体健康状况的影响，并对该地区放射工作人员的个人防护水平影响因素进行分析，发现可能存在的不利因素和问题，为放射工作人员的个人的身体健康提供科学依据，为制定相应的防护措施提供有针对性的建议。方法：收集苏州市放射工作人员2006~2012年的职业健康体检、放射防护培训及个人剂量监测数据，，导入Excel表格中，采用完全随机设计行×列表的卡方检验和CMH方法，分析职业健康体检指标的差异及其原因，放射防护培训的影响因素以及个人剂量结果。结果： 1.参加放射防护培训的人数呈逐年上升趋势，男性明显多于女性，工业领域男女职员的性别差异更大；非医用领域人数上升比医用领域人数上升快。每年参加放射防护培训的人员多于参加体检的人员；参加放射卫生培训的工作人员中，女性和医学领域的工作人员更多地参加职业健康体检。硕士以上文化水平的工作人员逐年增多，大学和高专文化程度人员最多的年份占总人数的86.11%。在参加培训的放射工作人员中，较高文化水平的从业人员更多地参加职业健康体检。 2.每年参加职业健康体检的人数逐年增多，且呈现年轻化的态势；B超和胸透检查结果的异常率逐年下降；血红蛋白年异常检出率高于红细胞、白细胞、血小板的年异常检出率；B超异常结果随工龄增加有增高的趋势；白细胞各放射工龄组间差异有统计学意义，20~30年工龄组的异常率较高。结论： 1.苏州市放射工作人员良好地参加了放射防护培训和职业健康体检。 2.医用电离辐射对放射工作人员健康状况产生一定的影响，但职业健康检查结果未见明显异常。 3.放射工作人员的年有效剂量符合国家标准。
[Abstract]:Objective: to analyze the data of occupational health examination, radiation protection training and personal dose monitoring of some radiation workers in Suzhou from 2006 to 2011. To observe the effects of occupational exposure on the physical health of radiation workers, and to analyse the factors affecting the level of personal protection of radiation workers in the region, and to identify possible adverse factors and problems, To provide scientific basis for the personal health of radiation workers, and provide targeted advice for the formulation of corresponding protective measures. Methods: the occupational health examination, radiation protection training and personal dose monitoring data of radiation workers in Suzhou from 2006 to 2012 were collected and imported into Excel form. The difference of occupational health examination index and its causes, the influencing factors of radiation protection training and the results of personal dose were analyzed. Results: 1. The number of participants in radiation protection training is increasing year by year, the number of men is obviously more than that of women, the gender difference of male and female workers in industrial field is even greater, and the number of non-medical field is rising faster than that of medical field. Each year more people attend radiation protection training than medical examinations; women and medical staff are more likely to take part in occupational health examinations. The number of staff with master's or higher education level increased year by year, and 86.11% of the total was in the year of university and college education. In the training of radiation workers, more highly educated practitioners participate in occupational health checkups. 2. The number of people attending occupational health examination increased year by year, and showed the trend of rejuvenation; the abnormal rate of B-ultrasound and chest radiography decreased year by year; the annual abnormal detection rate of hemoglobin was higher than that of red blood cells, white blood cells and platelets. The abnormal results of B-ultrasound showed a tendency to increase with the length of service, and the abnormal rate of white blood cell was higher in 20 ~ 30 years working age group than in the other two groups. Conclusion: 1. Suzhou radiation workers participated in radiation protection training and occupational health examination. 2. Medical ionizing radiation had a certain effect on the health status of radiation workers, but the results of occupational health examination were not obviously abnormal. The annual effective dose of radiation workers conforms to the national standard.
