| Abstract:: |
| Objective To study and analyze radiation doses to the eye of the lens dose in interventional radiology staff of Guandong medical institutions from 2019 to 2023. Methods Employing a convenience sampling method, the lens dose and chest dose was monitored with TLD dosimeters in 34 level A tertiary medical institutions. The monitoring data were analyzed on the basis of a summary, and the relationship between the two was explored. Results A total of 1 033 interventional radiology staff were monitored. The ocular lens doses were in the range of (< MDL-26.12 mSv), M (P25, P75) was 0.03 (< MDL, 0.20) mSv. The doses < MDL, MDL-, 1.25 mSv-, 5 mSv-, 10 mSv-, 20 mSv- were monitored for 428, 543, 48, 5, 6, and 3 times, respectively, accounting for 41.43%, 52.57%, 4.65%, 0.48%, 0.58% and 0.29% of total monitoring times, respectively. The ocular lens doses each year was, seperately, in the range of (< MDL- 0.42) mSv, (< MDL- 4.95) mSv, (< MDL- 26.12) mSv, (< MDL- 10.66) mSv, (< MDL-5.41) mSv. M (P25, P75) were < MDL (< MDL, < MDL) mSv, < MDL (< MDL, 0.04) mSv, 0.06 (< MDL, 0.16) mSv, 0.04 (< MDL, 0.24) mSv, 0.08 (< MDL, 0.27) mSv, respectively. The eye lens doses to the staff involved in neural intervention, cardiovascular intervention, digestive intervention, tumor intervention, peripheral vascular intervention and comprehensive intervention was (< MDL-3.85) mSv, (< MDL-13.77) mSv, (< MDL-1.38) mSv, (< MDL-1.24) mSv, (< MDL-4.54) mSv, (< MDL-26.12) mSv. Dose M (P25, P75) were 0.05 (< MDL, 0.16) mSv, 0.07 (< MDL, 0.28) mSv, 0.04 (< MDL, 0.09) mSv, 0.03 (< MDL, 0.03) mSv, < MDL (< MDL, 0.07) mSv, and 0.05 (< MDL, 0.32) mSv. The difference of ocular lens dose in staff among different interventional procedures was statistically significant (H = 49.85, P < 0.01). The higher doses were observed in staff in cardiovascular interventional radiology and comprehensive intervention. The lower doses were received by staff involved in tumor interventional procedures. The correlation between eye lens and chest dose were significant, as showm by spearman correlation test (R = 0.37, P < 0.001). The corelation fitted by linear regression function follows the formula: eye lens dose = 1.044×chest dose. Conclusions The monitoring results of lens dose in interventional radiology staff are generally good. The doses received by staff vary work type and interventional procedure. The priority in improvement of radiological protection should be given to staff involved in cardiovascular intervention and comprehensive intervention. |
