【摘要】：目的：通过对常熟市2004-2012年度医学放射工作人员职业健康体检资料的回顾性调查和分析,了解常熟市医学放射工作人员的职业健康情况,为今后管理机构制订和实施放射防护方案提供依据。方法：收集、汇总常熟市2004-2012连续9年1563人次医学放射工作人员的职业健康体检的眼晶体、心电图、血常规、肝功能、染色体畸变及微核细胞等指标,数据录入Excel表格中,建立数据库,对资料进行统计学分析。结果： 1.眼晶体和心电图检查随着放射工龄的增加,眼晶体的异常率呈上升趋势,放射工龄≥15年者眼晶体异常率明显高于正常对照组(P0.05)。医学放射工作人员心电图的异常率与正常人群相比无明显差异。 2.血液学指标2004-2006年白细胞计数均值明显低于正常对照组(P0.05)；血红蛋白异常检出率高于白细胞及血小板；血小板的异常检出率自2006年后明显降低,后呈波浪状改变。丙氨酸氨基转移酶、门冬氨酸氨基转移酶：不同放射工龄组与对照组相比,均无明显统计学差异(P0.05)。 3.染色体检查染色体畸变异常人数2004年明显高于正常对照组(P0.05)；2004、2005及2009年度微核细胞异常人数明显高于正常对照组。结论： 1.近10年常熟市医学放射工作人员职业健康状况总体良好。 2.医用电离辐射对放射工作人员健康产生一定的影响。 3.放射工龄超过15年者眼晶体、染色体损伤指标随工龄的增加而显著增高,呈累积性效应。
[Abstract]:Objective: Based on the retrospective investigation and analysis of medical radiation workers' occupational health examination data in Changshu City from 2004 to 2012, the occupational health status of medical radiation workers in Changshu City was studied. To provide the basis for the future management organization to formulate and implement the radiation protection program. Methods: To collect and summarize the indexes of eye lens, electrocardiogram, blood routine, liver function, chromosome aberration and micronucleus of 1563 medical radiation workers in Changshu City for 9 consecutive years from 2004 to 2012. The data were recorded in the Excel form and the database was established. The data were analyzed statistically. Results: 1. The abnormal rate of eye lens and electrocardiogram (ECG) showed an increasing trend with the increase of radiation duration. The abnormal rate of ocular lens in patients with 15 years of radiation service was significantly higher than that in the normal control group (P 0.05). There was no significant difference in the abnormal rate of electrocardiogram between the medical radiation workers and the normal population. 2. The mean value of leukocyte count from 2004 to 2006 was significantly lower than that of normal control group (P 0.05), the abnormal detection rate of hemoglobin was higher than that of white blood cell and platelets, and the abnormal detection rate of platelet decreased significantly after 2006, and then showed wave change. Alanine aminotransferase and aspartate aminotransferase: there was no significant difference between the different radiation age groups and the control group (P 0.05). 3. The number of chromosomal aberrations in 2004 was significantly higher than that in the normal control group (P0.05 / 2004,2004,2005,2009), and the number of abnormal micronucleus cells in 2004 was significantly higher than that in the normal control group. Conclusion: 1. The occupational health status of medical radiation workers in Changshu City was good in recent 10 years. 2. Medical ionizing radiation has a certain effect on the health of radiation workers. 3. The chromosome damage index of the eyes with more than 15 years of radiation service increased significantly with the increase of the length of service, and showed a cumulative effect.
