More than half of material thefts reported to IAEA occurred during transport
The International Atomic Energy Agency has said that more than half of all thefts of nuclear and other radioactive material reported to the agency’s Incident and Trafficking Database (ITDB) since 1993 occurred during authorized transport, with the share rising to nearly 70 percent in the past decade. The ITDB covers incidents involving nuclear material, radioisotopes, and radioactively contaminated material.
