Mexico issues alert after medical radioactive material theft
Mexican authorities have issued a preventive alert across seven states following the theft of medical radioactive material in Tlaxcala. The incident occurred during the early hours of November 7, 2026, after a vehicle transporting the cargo overturned on the Huamantla-Tlaxcala highway.
The stolen shipment, which originated from the National Institute of Nuclear Research (ININ) in the State of Mexico and was destined for Xalapa, Veracruz, consists of nine boxes. The materials include three boxes of Technetium generators, four boxes of Iodine-131, one box of Thallium, and one box of Samarium.
The National Commission for Nuclear Safety and Safeguards (CNSNS) has classified the material as Category 4 according to the International Atomic Energy Agency (IAEA) scale, indicating a relatively low risk. However, officials warned that direct exposure without protection could pose health risks, especially if the containers are damaged or opened.
The National Civil Protection Coordination (CNPC) has extended the alert to Tlaxcala, Veracruz, Puebla, Morelos, Hidalgo, the State of Mexico, and Mexico City to facilitate the search. Authorities have instructed the public not to touch, open, or move any suspicious containers and to maintain a safety perimeter of at least five meters if such objects are found.
