Abstract

The iodine-131 (I-131) content in the thyroid of staff members working with this radionuclides has been measured with about 500 employees in about 25 hospital's departments of nuclear medicine performing therapy and diagnosis of thyroid disease in Poland. The measurements were performed with portable detection unit for in situ measurements of radioiodine. This is consist with scintillation detector sodium iodine activated by thallium (NaI(Tl)) - battery-powered and portable tube base Multichannel Analyzer Canberra UniSPEC. Based on direct measurements of the iodine content, the effective dose equivalent for workers due to inhalation of I-131 was estimated. All individuals actively working with iodine show measurable amounts of this isotopes in their thyroids. The average measured activity in the thyroid of the nuclear medicine staff was found to be equal at average 550 Bq within the range 70 Bq-2.5 kBq. There is no apparent correlation between the measured I-131 levels and risk categories. Nevertheless the technical and nuclear medicine staff show higher I-131 thyroid level comparing to hospital services staff. Calculated maximum committed effective dose for particular exposed person is <10% of 20 mSv/year. Int J Occup Med Environ Health. 2023;36(5):587-95.

波兰从事放射性碘工作的核医学工作人员的内部暴露评估。

波兰约25家医院核医学部门的约500名员工对使用这种放射性核素的工作人员甲状腺中的碘-131（I-131）含量进行了测量，这些员工正在进行甲状腺疾病的治疗和诊断。测量是用便携式检测装置进行的，用于放射性碘的原位测量。这是由铊激活的闪烁探测器碘化钠（NaI（Tl））电池供电和便携式管基多通道分析仪Canberra UniSPEC组成。根据碘含量的直接测量，估计了工人因吸入I-131而产生的有效剂量当量。所有积极从事碘工作的人在甲状腺中都显示出可测量的碘同位素量。核医学工作人员甲状腺的平均测量活动被发现在70Bq-2.5kBq的范围内平均550Bq相等。测量的I-131水平与风险类别之间没有明显的相关性。然而，与医院服务人员相比，技术和核医学人员的I-131甲状腺水平更高。特定接触者的计算最大承诺有效剂量为
