Last updated Apr 5, 2026|Official source

Summary

Radioactive material that gives off ionizing radiation on its own can be carried on passenger airplanes on commercial flights only if it is meant for research or for medical diagnosis or treatment and it does not create an unreasonable risk to health or safety while being packed or flown. The Secretary must set up ways to monitor and enforce these rules. The Secretary can also say that very low‑radioactivity materials that do not pose a significant health or safety risk during transport are not covered.
