This article presents an analysis of issues related to low-dose radiation, with a focus on pediatric computed tomography (CT). It references several early studies that are seldom quoted in radiation research papers, then quantifies the excess lifetime fatal cancer yield attributable to an estimated 6.5 million pediatric abdominal CT scans. The authors highlight an important policy document issued jointly by the National Cancer Institute and the Society for Pediatric Radiology--specifically, its conclusion that a small dose from CT represents "a public health concern." Finally, the article identifies several contentious issues and proposes policy initiatives that, if implemented, could result in significant reductions of future radiogenic cancers and chronic injuries. The authors call for discussions between professional radiology societies and public interest health organizations, thereby involving all stakeholders.
本文对与低剂量辐射相关的问题进行了分析，重点关注儿科计算机断层扫描（CT）。它引用了一些在辐射研究论文中很少被引用的早期研究，然后对因估计650万次儿科腹部CT扫描导致的终身额外致命癌症发生率进行了量化。作者强调了美国国家癌症研究所和儿科放射学会联合发布的一份重要政策文件，特别是其关于CT小剂量辐射代表“公共卫生问题”的结论。最后，本文指出了几个有争议的问题，并提出了一些政策倡议，如果实施，可能会显著减少未来的放射性癌症和慢性损伤。作者呼吁专业放射学会和公共利益健康组织之间进行讨论，从而让所有利益相关者参与进来。
