目的了解我市放射工作人员健康状况,以便改进防护措施,减少电离辐射损伤,进一步提高我市放射工作人员健康水平。方法依据卫生部第23号令《职业健康监护管理办法》对我市669名放射工作人员进行临床检查和实验室检查,并对其体检资料进行统计学处理。结果随着工龄的增加,手指纵嵴色条甲人数比率及眼晶状体混浊率有增高的趋势,不同工龄组差异有统计学意义(P<0.005);同时各工龄组中外周血象和肾功检查各项指标均值都在正常范围以内,各工龄组各项指标无统计学意义(P>0.05);随着工龄的增加,微核细胞率和微核率呈增高的趋势,且有统计学意义(P<0.05);随着工龄的增加,B超检查的异常率呈增高的趋势,但无统计学意义(P>0.05),影像学检查中其他两项指标增高或降低呈波动性改变,未见规律性变化。结论长期小剂量接触电离辐射仍可使机体产生一定的辐射损伤,应该进一步加强辐射防护工作。
Objective To understand the health of radiation workers in our city in order to improve protective measures to reduce ionizing radiation damage and further improve the health of radiation workers in our city. Methods Based on the Order No.23 of the Ministry of Health, “Occupational Health Monitoring and Management Measures”, we conducted clinical and laboratory examinations on 669 radiological workers in our city and conducted statistical tests on their physical examination data. Results With the increase of seniority, the ratio of the number of color bars in the longitudinal crest of fingers and the opacification rate of ocular lens tended to increase. There were significant differences in different age groups (P <0.005). At the same time, the peripheral blood and renal function tests The mean value of each index was within the normal range, and there was no significant difference in each age group (P> 0.05). With the increase of working age, the rate of micronuclei and micronucleus rate showed a trend of increase with a statistically significant (P <0.05). With the increase of seniority, the abnormal rate of B-ultrasound showed an increasing trend, but there was no statistical significance (P> 0.05). The other two indexes in the imaging examination increased or decreased in a fluctuating manner, No regular changes. Conclusion Long-term low-dose exposure to ionizing radiation can still cause certain radiation damage to the body, and radiation protection should be further strengthened.
