説明
<jats:title>Abstract</jats:title> <jats:p>To determine the eye lens dose (3 mm dose equivalent [Hp(3)]) received by spine surgeons during myelography and evaluate the effectiveness of radiation-protective glasses and x-ray tube system positioning in reducing radiation exposure. This study included spine surgeons who performed myelography using over- or under-table x-ray tube systems. Hp(3) was measured for each examination using a radio-photoluminescence glass dosimeter (GD-352M) mounted on radiation-protective glass. This study identified significantly high Hp(3) levels, especially in the right eye lens in spinal surgeons. The median Hp(3) values in the right eye were 524 (391–719) and 58 (42–83) <jats:italic>μ</jats:italic>Sv/examination for over- and under-table x-ray tube systems, respectively. Further, Hp(3)<jats:sub>AK</jats:sub>, which was obtained by dividing the cumulative air kerma from Hp(3), was 8.09 (6.69–10.21) and 5.11 (4.06–6.31) <jats:italic>μ</jats:italic>Sv mGy<jats:sup>−1</jats:sup> for the over- and under-table x-ray tube systems, respectively. Implementing radiation-protective glasses resulted in dose reduction rates of 54% (50%–57%) and 54% (51%–60%) for the over- and under-table x-ray tube systems, respectively. The use of radiation protection glasses significantly reduced the radiation dose in the eye lens during myelography, with the most effective measures being the combination of using radiation protection glasses and an under-table x-ray tube system.</jats:p>
