The State provided the following information via email:
DRH notified by NuMedRx Nuclear Pharmacy RSO that one of their delivery vehicles had been involved in an accident on Highway 49 North at the Highway 16 intersection. Apparently, the vehicle was struck by a school bus while it was en route to making a delivery to a Greenville, MS facility. No students were on the bus at the time of the collision. Apparently, law enforcement personnel did not realize the vehicle was transporting radioactive materials and no notifications were made to MEMA. DRH was not notified until after the vehicle was removed by the wrecker service. DRH responded to the wrecker service facility to survey and retrieve the transport container. The transport container was not ejected from the vehicle; however, the package was turned over and was not secured by the straps anymore. The package was labeled 'Yellow II' and still secured by the tamper seal. No leakage was detected [levels were 0.4 mR/hr at the surface of transport container] and radioactive doses/package were returned to RSO at the Jackson, MS nuclear pharmacy.
The delivery vehicle was carrying Thallium-201 and Technetium-99m totaling 13 millicuries.
