| 摘 要： | 目的 分析和评价125I粒子植入治疗术中不同操作者辐射剂量水平。 方法 用热释光(TLD)元件作为测量工具, 检测参与粒子操作手术的不同操作者(CT引导者、超声引导者、粒子植入者)眼晶状体、操作的手部位和甲状腺部位的辐射剂量水平, 估算眼晶状体、操作的手部位和甲状腺当量剂量。 结果 不同操作者间眼晶状体、操作的手部位和甲状腺当量剂量之间差异无显著统计学意义, 且未超出《电离辐射防护与辐射源安全基本标准》(GB-18871-2002)规定放射工作人员的剂量限值。 结论 参与粒子植入术的不同操作者在本研究的工作强度下, 眼晶状体当量剂量未超过ICRP最新推荐的眼晶状体剂量限值(20mSv), 操作的手部位当量剂量也未超过手部剂量限值(500 mSv)。

| Abstract: | Objective This study aims to assess the level of radiation exposure of 125I seed implantation operators. Methods Using thermoluminescent dosimeters for dose measurement, the radiation exposures of eye lens, operating hands, and thyroid of CT guider, ultrasound guider, and125I implanting operator were measured when 125I seeds were implanted.The equivalent dose to the eye lens, operating hands, and thyroid was estimated. Results No significant differences in the annual equivalent dose of the eye lens, operating hands, and thyroid were found among the three operators.It did not exceed the limit of the Protection against Ionizing Radiation and the Safety of Radiation Sources basic standard(GB-18871-2002). Conclusion The eye lens of operators involved in 125I seed implantation will receive an equivalent dose of less than 20 mSv, as recommended by the ICRP under the condition provided by our study.The operating hands of the operators involved in 125I seed implantation will receive the recommended equivalent dose of less than 500 mSv. |
