| Abstract:: |
| Objective To analyze and learn about the dose to the lens of the eye of interventional radiology workers in some hospitals in shaanxi province from 2018 to 2020.Methods From 2018 to 2020, three tertiary hospitals in shaanxi province were selected to monitor the dose to the lens of the eye of interventional radiology workers for three consecutive years. Monitoring was made for 152 person times, lasting for a monitoring period of 3 months. Analysis and comparison were carried out of dose equivalents to the interventional radiology workers in terms of different sexes, positions and departments, together with associated influencing factors during the three years.Results The difference in equivalent dose between the three years is statistically significant (χ2=29.15, P < 0.05), and a downward trend in the average annual equivalent dose was found from 2018 to 2020. The number of interventional radiology workers who received doses to the lens of the eye mainly between MDL and 5.0 mSv accounted for 69.08%. The difference in the average annual equivalent dose in different positions and departments was statistically significant (H=18.44, 22.55, P < 0.05). The average annual equivalent dose to doctor was higher than for nurses and technicians (Z=-3.36, -3.02, P < 0.05). The average annual equivalent dose in cardiovascular medicine department was higher than in other departments, with statistically significant difference (Z=-2.58, -3.76, -3.40, P < 0.05). Logistics regression analysis showed that radiation working hours, positions, routine personal doses, workload and exposure time are the factors that affect the average annual equivalent dose.Conclusions The annual equivalent dose to the lens of the eye of interventional radiology workers in shaanxi province meets the relevant national standards. However, the annual dose to some radiological workers has a normal high value. Therefore, it is necessary to strengthen the continued monitoring of the dose to the lens of the eye of the interventional radiology workers, and adjust the types of work for the workers based on radiation work hours, position, routine personal dose, workload and exposure time, so as to effectively reduce the dose level of the eye lens. |
