This study aimed at minimizing secondary radiation exposure of the crystalline lens during the computed tomography to medical staff who help unconscious emergency patients. In particular, the radiation high-sensitivity crystalline lens should maintain a effectiveness dose limit of 150 mSv/y. Therefore, adequate shielding is required for the protection of the crystalline lens by secondary radiation. In this study, acrylic plates were used to shield secondary radiation. The focus was on the secondary radiation from the gantry region of the computed tomography. because the position of the assistants matches the gantry portion. The radiation dose rate was measured by increasing the thickness on the acrylic plate. As a result, the secondary radiation dose could not be rapidly shielded as the thickness of the acrylic plate increased. However, the secondary radiation dose of 5-20% decreased with increasing acrylic plate thickness.
