摘　　要：为弥补目前国内外精密异形放射源制备工艺的不足,将3D打印技术引入放射源制备领域。本研究采用相转移方法制备^(133)Cs3D打印用光敏树脂,使用高分辨电感耦合等离子体质谱(ICP-MS)进行检测,探索制备条件。并通过溴化镧探测器对制备的^(137)Cs3D打印用光敏树脂材料进行检测。结果表明,通过相转移方法制备的三种^(133)Cs3D打印用光敏树脂和^(137)Cs3D打印用光敏树脂中铯元素分布不均匀度<5%。相转移法作为一种操作简便、反应条件温和的方法可用于制备含有铯元素的3D打印用光敏树脂,且具有一定普适性。To introduce 3D printing technology into the field of radiation source preparation and make up for the lack of precision special-shaped radiation source preparation technology at home and abroad.The photosensitive resin for^(133)Cs3D printing was prepared by studying the phase transfer method and detected by ICP-MS to explore the preparation conditions.Then,the photosensitive resin material for^(137)Cs3D printing was prepared and detected by lanthanum bromide detector.The results show that the uneven distribution of cesium in three photosensitive resins for^(133)Cs3D printing and^(137)Cs3D printing prepared by phase transfer method was less than 5%.As a simple and mild method,phase transfer method can be used to prepare photosensitive resin for 3D printing containing cesium,and has certain universality.
