A cesium-137 radioactive capsule was reported stolen from a medical/laboratory facility in Argentina on or around 18 June 2026, prompting a national alert and forensic work by authorities and the nuclear regulator. Corroborating reporting places the incident at a medical centre in Rosario, while an earlier source references a facility at La Nacion in the Chaco province area. The capsule had not been publicly confirmed as recovered as of available reporting, and no insured-asset loss, casualty figures, or commercial property damage have been evidenced.

Impact verdict

Low impact. LOW: Theft of a radiological source raises public-safety and potential operator/custody liability concerns, but no insured-asset loss, named insured operator, loss estimate, or direct commercial/industrial property damage is evidenced. The geographic locus remains in conflict between Rosario and Chaco province, and the capsule's recovery status is unconfirmed. No insured-industry figure is present to floor or cap severity; potential impact remains low until operator identity, recovery status, or contamination pathway is established.
