Lead containing dust may be present on the exterior surfaces of shields used to prevent radiation exposure. We determined whether use of lead shields poses an exposure risk for radiology personnel. We collected hand dustwipe and blood samples from 58 Radiology Department employees of an academic hospital. Samples were analyzed for lead content by atomic absorption spectroscopy. Results were compared between lead apron users (46) and nonusers (12). Hand dustwipe lead was undetectable (<3 µg/sample) in all cases. Blood lead levels ranged from 0-3 µg/dL. In this study of Radiology Department workers, we did not find an increased risk of lead contamination on their hands or in their blood. Although our sample size is small, we conclude that lead poisoning is unlikely to occur with high frequency in lead shield users.
用于防止辐射暴露的防护屏外表面可能存在含铅灰尘。我们确定了使用铅防护屏是否会给放射科工作人员带来暴露风险。我们从一家学术医院的58名放射科员工那里收集了手部灰尘擦拭样本和血液样本。通过原子吸收光谱法分析样本中的铅含量。比较了铅围裙使用者（46人）和非使用者（12人）的结果。所有情况下手部灰尘擦拭样本中的铅均未检测到（<3微克/样本）。血铅水平在0 - 3微克/分升之间。在这项针对放射科工作人员的研究中，我们没有发现他们手部或血液中铅污染风险增加。尽管我们的样本量较小，但我们得出结论，铅防护屏使用者不太可能频繁发生铅中毒。
