Diagnostic examinations in nuclear medicine increase. This can cause a higher radiation burden to the personnel. The aim of this study was to create and apply a method to validate the occupational radiation protection at the Department of Nuclear Medicine using thermoluminescence dosemeters (TLD). Occupational doses in- and outside of the department and the dose rate distribution around the positron emission tomography/computed tomography (PET/CT) were validated in terms of Hp(10) using TLD-100. Backscatter correction factors were estimated to implement the TLD measurements on different materials. After correction for backscatter, the result indicates that doses in- and outside of the department are below recommended values and dose limits. The highest and the lowest dose rate were measured beside the 18F-autoinjector and the PET/CT gantry, respectively. The method of using TLD gives a good estimate of how the occupational radiation protection performs at the Department of Nuclear Medicine and can thus help in the optimization of radiation protection.

在核医学部使用 TLD 测量验证职业辐射防护的潜力

核医学诊断检查增加。这会对人员造成更高的辐射负担。本研究的目的是创建并应用一种方法来验证核医学系使用热释光剂量计 (TLD) 的职业辐射防护。使用 TLD-100 根据 Hp(10) 验证部门内外的职业剂量以及正电子发射断层扫描/计算机断层扫描 (PET/CT) 周围的剂量率分布。估计反向散射校正因子以在不同材料上实施 TLD 测量。在对反向散射进行校正后，结果表明部门内外的剂量低于推荐值和剂量限值。在 18F 自动注射器和 PET/CT 龙门架旁边测量了最高和最低剂量率，分别。使用 TLD 的方法可以很好地估计核医学系职业辐射防护的执行情况，从而有助于优化辐射防护。
