PASCO, Wash. (AP) -- An emergency operations alert was activated at Hanford overnight after radiation was detected during a transfer from a waste tank.
KONA-AM radio reports the Department of Energy activated the alert around 9:20 p.m. Wednesday near tank C-101.
A leak was detected and operations halted, while employees took shelter in the areas surrounding the source of the alert.
The take cover ordered was lifted after an additional survey of the tank farm area found no detectable radiation. Workers returned to work as normal but officials planned to investigate the incident further.
