- W4386079551 abstract "OBJECTIVE Protection from radiation-induced cataracts for radiation workers is an important issue, as indicated by the ICRP. In this study, we developed the software ``X-scatter-STK-2'' which can evaluate lens dose in publicly available software that enables dose evaluation for workers under various conditions. MATERIALS & METHODS We developed a software program that can calculate conversion coefficients of lens dose and 3 mm dose equivalent from air kerma of scattering angle corresponding to changes in irradiation conditions. From these conversion coefficients, we examined whether the protective effect of protective eyewear and the energy spectrum could also be verified. Furthermore, we used a phantom to examine the difference in the evaluation. RESULTS The larger the scattering angle, the different the conversion coefficients were, and the smaller the transmittance. The transmission was about 35% at 80 kV, 0.07 mm Pb thickness, and 90° scattering angle, and about 30% at 135° scattering angle. The transmittance increased with increasing tube voltage, and the same trend was observed at 0.85 mmPb. In the phantom measurements, the differences were smaller than in the simulation results, although the differences were caused by the scattering angle, tube voltage, and other factors. CONCLUSION The lens doses measured with protective eyewear were slightly different due to the scattering angle and other factors, but there was no difference in the trend. Valuable data on lens protection measures in clinical practice can be easily obtained. This software is available free of charge and can be used for educational purposes.
