This study investigated lead concentrations in the hairs of radiographers working in the radiological departments of general hospitals that used lead shielding for radiation protection. We collected scalp hair samples from 32 radiographers working in four radiology departments with lead shielding and 18 administration personnel in the same hospitals without lead shielding. Samples were analyzed for lead concentrations by inductively coupled plasma mass spectrometry. As a result, lead concentrations in the hairs of the radiological technologists were significantly higher than those in the administration staffs (0.72 ± 0.51 vs. 0.19 ± 0.27 μg/g, P < 0.001). The hair lead concentrations were positively and significantly associated with environmental lead concentrations (r = 0.6, P = 0.001), but not associated with age, working duration, and gender distribution.
这项研究调查了在使用铅屏蔽进行放射防护的综合医院放射科工作的放射技师头发中的铅浓度。我们从四个放射科部门的 32 名使用铅屏蔽的放射技师和同一医院的 18 名行政人员中采集了头皮头发样本。样本通过电感耦合等离子体质谱法进行铅浓度分析。结果表明，放射技师的头发中的铅浓度明显高于行政人员（0.72±0.51 与 0.19±0.27μg/g，P<0.001）。头发中的铅浓度与环境中的铅浓度呈正显著相关（r=0.6，P=0.001），但与年龄、工作年限和性别分布无关。
