A box labeled “radioactive” that was found outside a Lafayette car repair shop Tuesday morning caused a brief scare and road closures but was eventually determined to be harmless, a Contra Costa County sheriff’s spokesman said.
The bright-green box, marked with a “radioactive” sticker, was spotted by employees at Lafayette Auto Repair at 3410 Mt. Diablo Blvd., and they reported it to police around 8:20 a.m., Contra Costa County sheriff’s spokesman Jimmy Lee said.
Police and fire crews arrived at the scene a short time later and shut down the intersection of Mt. Diablo Boulevard and Brown Avenue while hazardous materials personnel from the California Emergency Management Agency were called in to investigate, Lee said.
An inspection of the box found that it contained a ground-penetrating radar, Lee said. Such radars are used to capture three-dimensional images of underground surfaces.
The hazmat team determined that the radar was not dangerous, Lee said. He said investigators were now working to find the box’s owner.
The intersection has since reopened.
