Nuclear medicine technicians work daily with radioactive isotopes, and therefore receive a certain amount of radiation dose. The aim of this study was to assess the radiation dose, during various tasks, to the technicians at four nuclear medicine departments and to investigate to what extent there are differences between the departments and possible reasons for such. Measurements were made at nuclear medicine departments at four Norwegian hospitals. Doses to the technicians were measured with an educational direct dosimeter-instrument worn outside the lead apron during work at hot-lab, administrating the injection and image acquisition. Calculated annual collective and individual doses were compared with data from personal dosimetry. A value of ∼1 nSv MBq(-1) seems to be representative for modern Norwegian nuclear medicine departments. In departments with upgraded hot-labs, the largest dose contribution is received during image acquisition.
核医学技术人员每天都要接触放射性同位素，因此会接受一定剂量的辐射。本研究的目的是评估四个核医学科室的技术人员在各种任务期间所接受的辐射剂量，并调查各科室之间的差异程度以及造成这种差异的可能原因。测量工作在挪威四家医院的核医学科室进行。在热室工作、进行注射和图像采集时，通过佩戴在铅围裙外的教育用直接剂量计仪器来测量技术人员所接受的剂量。将计算得出的年度集体剂量和个人剂量与个人剂量测定数据进行比较。约1 nSv MBq(-1) 的值似乎代表了现代挪威核医学科室的情况。在热室升级的科室中，图像采集期间接受的剂量贡献最大。
