As chest x rays involve risks of patients falling, radiologic technologists (technologists) commonly assist patients, and as the assistance takes place near the patients, the eye lenses of the technologists are exposed to radiation. The recommendations of the International Commission on Radiological Protection suggest that the risk of developing cataracts due to lens exposure is high, and this makes it necessary to reduce and minimize the exposure. The present study investigated the positions of technologists assisting patients that will minimize exposure of the eye lens to radiation. The results showed that it is possible to reduce the exposure by assisting from the following positions: 50% at the sides rather than diagonally behind, 10% at the right side of the patient rather than the left and 40% at 250 mm away from the patient. The maximum reduction with radiation protection glasses was 54% with 0.07 mmPb and 72% with 0.88 mmPb.

尽量减少放射技术人员在胸部 X 光检查期间协助患者的眼睛接触：一项体模研究

由于胸部 X 射线涉及患者跌倒的风险，放射技师（技师）通常会协助患者，并且由于在患者附近进行援助，技师的眼部晶状体会受到辐射。国际放射防护委员会的建议表明，由于晶状体暴露导致白内障的风险很高，因此有必要减少和尽量减少暴露。本研究调查了协助患者的技术人员的职位，这些职位将最大限度地减少眼睛晶状体暴露于辐射。结果表明，可以通过以下位置的协助来减少暴露：50% 在侧面而不是斜后方，10% 在患者右侧而不是左侧，40% 在距离患者 250 毫米处病人。
