After unloading the truck, firefighters from the hazardous materials unit of the city of Linz found nearly two dozen diapers from a hospital that had become contaminated with radioactive iodine. The substance is swallowed during some medical and diagnostic procedures.
While radiation levels were substantially above normal, unit leader Dieter Jonas says no one was in danger during Tuesday's incident.
Austrian officials, however, are tracing the truck's route. And the truck will stay in a metal container at the incinerator for eight days - the time it takes for the emissions to reach safe levels.
