Abstract The Institute for Advanced Medical Isotopes (IAMI) is TRIUMF's new facility dedicated to the research and production of medical isotopes. This work details the shielding requirements and radiological studies performed during the facility design. The initial design was based on the existing TR30-2 machine at TRIUMF, and then refined using Monte Carlo (MC) simulations. These calculations were performed with the MC particle transport and interaction code FLUKA, in several iterations, until occupancy and dosimetry requirements were met. The simulation results here documented, besides validating the shielding design, were also used to reduce materials' cost, optimize services' location as well as in the decommission study.

IAMI 设施的屏蔽评估

摘要 高级医用同位素研究所 (IAMI) 是 TRUMF 致力于研究和生产医用同位素的新设施。这项工作详细说明了设施设计期间进行的屏蔽要求和放射学研究。最初的设计基于 TRUMF 现有的 TR30-2 机器，然后使用蒙特卡罗 (MC) 模拟进行改进。这些计算是使用 MC 粒子传输和相互作用代码 FLUKA 进行的，经过多次迭代，直到满足占用率和剂量学要求。此处记录的模拟结果除了验证屏蔽设计外，还用于降低材料成本、优化服务位置以及退役研究。
