This study used thermoluminescent dosimeters (TLDs) to measure cumulative radiation doses in a PET/CT center. It covered 18 areas and four personnel groups. Because the isolated lead shielding separated the patients from the nurses, wearing protective clothing when injecting radiopharmaceuticals was unnecessary. Fingertip doses of the dispensing and nurse groups were below the occupational limit. Current radiopharmaceutical transportation and injection operations in this PET/CT center provide considerable radiation protection to medical personnel.

医院 PET/CT 中心的环境和人员职业剂量评估

本研究使用热释光剂量计 (TLD) 来测量 PET/CT 中心的累积辐射剂量。它涵盖了18个领域和4个人员组。由于隔离铅屏蔽将患者与护士隔开，因此注射放射性药物时无需穿防护服。配药组和护士组的指尖剂量低于职业限制。该 PET/CT 中心目前的放射性药物运输和注射操作为医务人员提供了相当大的辐射防护。
