Abstract:
Objective To investigate the levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent Hp(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q1, Q3) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ2 = 9.149, P = 0.002, OR = 8.343), eye protection (χ2 = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ2 = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.
