Personal Dose Testing and Occupational Health Data Analysis of Radiation Workers in a Hospital for Three Years
Objective To analyze the three-year personal dose testing and occupational health data of radiation workers in a certain hospital,and to explore the differences in radiation doses received by different occupational categories and the protective effects of radiation workers.Methods This study analyzed the personal dose levels and occupational health data of 7 440 radiation workers in a first class hospital over a period of three years.Results The study found that the personal effective dose distribution range of personnel engaged in interventional medicine was significantly higher than that of other practitioners,especially in the>3.0 mSv range of interventional medicine for 3 people,while in nuclear medicine and diagnostic radiology for 1 person each.But overall analysis showed that radiation workers engaged in nuclear medicine had significantly higher personal doses than other occupational categories,the differences were statistically significant(P<0.05).At the same time,this study also found that the abnormal rate of abdominal ultrasound in radiation workers engaged in interventional medicine was 42.31%,far higher than the average level of 31.13%.The abnormal detection rate of blood pressure and abdominal ultrasound in nuclear medicine majors was significantly higher than that in other occupational categories(P<0.05).Conclusion In the past three years,interventional medicine received the highest radiation dose among radiation workers,with a relatively high distribution range of effective doses,while nuclear medicine had the highest per capita annual effective dose.At the same time,the abnormal rate of abdominal ultrasound in interventional medicine is much higher than the average level,while in nuclear medicine,the abnormal detection rate of items such as blood pressure and abdominal ultrasound is significantly higher than other occupational categories.
