This paper summarizes the dose to the eye lens of workers of Memorial Sloan Kettering Cancer Center, a high-volume US oncologic and associated diseases facility. The doses presented in this report were collected from personal dosemeter readings using optically stimulated luminescence badges to estimate Hp(3). Doses were collected for 5950 clinical and research workers between January 2012 and December 2017. The median eye lens dose for all monitored workers was 0.23 mSv y-1. Workers performing, or supporting, fluoroscopy procedures received the highest unprotected eye lens dose of all workers with a median eye dose of 10 mSv. The use of leaded glasses by this group reduced the actual doses to the lens. Nurses and technicians involved in positron emission tomography injections received median eye lens dose of 1.2 mSv.
本文总结了美国一家大型肿瘤及相关疾病治疗机构——纪念斯隆凯特琳癌症中心工作人员的晶状体受照剂量。本报告中的剂量数据是通过使用光激发发光徽章进行个人剂量计读数收集的，以估算Hp(3)。在2012年1月至2017年12月期间，收集了5950名临床和研究人员的剂量数据。所有受监测工作人员的晶状体剂量中位数为0.23 mSv·y-1。在所有工作人员中，进行或辅助荧光透视程序的人员未受保护的晶状体剂量最高，晶状体剂量中位数为10 mSv。该组人员使用铅玻璃降低了晶状体的实际受照剂量。参与正电子发射断层扫描注射的护士和技术人员的晶状体剂量中位数为1.2 mSv。
