An incident along U.S. Highway 66 near Lambert-St. Louis Field resulted in radioactive dirt spilling onto the highway after a dump truck overturned. According to the Atomic Energy Commission's St. Louis area manager, the hazardous material originated from a project at Mallinckrodt Chemical Works.
Emergency responders arrived at the scene and worked to contain the spread of radioactive material and mitigate risk to the public and the environment. Traffic was diverted away from the scene to prevent further exposure and public health officials monitored air and water quality.
Investigations will be looking into how the spill occurred and will likely spark potential discussions around strengthening regulatory oversight and enhancing protocols for similar projects.
