Positron emission tomography (PET) is now one of the most important methods in the diagnosis of cancer diseases. Due to the rapid growth of PET/CT centres in Poland in less than a decade, radiation protection and, consequently, the assessment of worker exposure to ionising radiation, emitted mainly by the isotope (18)F, have become essential issues. The main aim of the study was to analyse the doses received by workers employed in the Medical Diagnostic Centre. The analysis comprises a physicist, three nurses, three physicians, three technicians, as well as two administrative staff employees. High-sensitivity thermoluminescent detectors (TLDs) were used to measure the doses for medical staff. The personnel was classified into categories, among them employees having direct contact with the 'source of radiation'-(18)FDG. The TLDs were placed on the fingertips of both hands and they were also attached at the level of eye lenses, thyroid and gonads depending on the assigned category. The highest dose of radiation was observed during the administration of the (18)FDG to the patients. In the case of the physicist, the highest dose was recorded during preparation of the radiopharmaceutical-(18)FDG. The body parts most exposed to ionizing radiation are the fingertips of the thumb, index and middle finger.
正电子发射断层扫描（PET）现在是癌症疾病诊断中最重要的方法之一。由于在不到十年的时间里波兰PET/CT中心的迅速增加，辐射防护以及对主要由同位素（18）F发出的电离辐射的工作人员暴露评估已成为至关重要的问题。该研究的主要目的是分析医疗诊断中心工作人员所接受的剂量。分析对象包括一名物理学家、三名护士、三名医生、三名技术人员以及两名行政人员。高灵敏度热释光探测器（TLD）用于测量医务人员的剂量。人员被分类，其中包括与“辐射源”——（18）FDG有直接接触的员工。TLD放置在双手的指尖上，并且根据指定类别还附着在眼镜、甲状腺和性腺水平处。在给患者注射（18）FDG期间观察到最高辐射剂量。就物理学家而言，在制备放射性药物——（18）FDG期间记录到最高剂量。最易受到电离辐射的身体部位是拇指、食指和中指的指尖。
