The Stimson Center created two spreadsheets of UN Member States’ legal measures that include an explicit obligation to secure radioactive sources, related apparatus, or facilities to empower stakeholders with a better understanding of what States have done to address this challenge.  In addition to putting together a compendium of legal texts, the Stimson Center has evaluated the measures against key elements of the IAEA’s Code of Conduct on the Safety and Security of Radioactive Sources.

The Radiological Sources Security Measure Level Database includes 237 measures for 145 UN Member States. Measures with explicit obligations to secure radioactive sources could not be found for 48 UN Member States.

The Radiological Sources Security State Level Database offers analysis of all 193 UN Member States’ legal efforts to secure radiological sources.

To better understand what the databases show, Stimson has also included the Codebooks used to develop and assess each of the security databases as PDFs.

Should you have questions about the Codebook or the database, please contact Christina McAllister, Senior Fellow & Director of the Partnerships in Proliferation Prevention Program.
