Correlations between occupational radiation exposure to the lens of the eyes (mSv) and radiation exposure to patients (air kerma at the patient entrance reference point (K_a,r: mGy), air kerma-area product (P_KA; Gycm²), fluoroscopy time (FT; min)). r: correlation coefficient, p: probability value of the correlation coefficient, R²: coefficient of determination. a–c Radiation exposure to the lens of the eyes of operators and radiation exposure to patients (a K_a,r, b P_KA, c FT). 2d-f: Radiation exposure to the lens of the eyes of assistants and radiation exposure to patients (d K_a,r, e P_KA, f FT). g–i Radiation exposure to the lens of the eyes of nurses and radiation exposure to patients (g K_a,r, h P_KA, i FT).
