An 18-wheeler carrying 12, 20 gallon lead-lined containers of the radioactive substance Scandium was rear ended around 6 p.m. Monday along Interstate 10 West in the eastbound lanes near Medical Drive.
Emergency crews shutdown all eastbound lanes of I-10 at Medical because of the nature of the substance, which according to the San Antonio Fire Department, is found in trace amounts if petroleum products.
HAZMAT crews and the SAFD bomb squad were called to the scene to investigate and monitor radiation levels.
"The containers do not appear to be breached," says SAFD spokesperson, Deborah Foster. "The fact that they are lead-lined containers inside that vehicle, it actually has double protection."
Foster said the Scandium did not pose a threat to drivers passing by along the eastbound access road or westbound I-10 and no radiation levels were detected in the environment.
The truck was en route to Alice, Texas. No word on where it was coming from.
Crews planned to board the truck to be sure the containers were not breached and to determine that the truck could be safely moved.
We are told I-10 West was opened around 10 p.m.
