Nuclear officials told a citizen's advisory board recently that a minor accident last year temporarily shut down work at a cleanup site in eastern Idaho and exposed a staffer to low levels of radiation.
Idaho Cleanup Project spokesman Mark Brown has said the accident Oct. 23 at the Idaho National Laboratory site came as workers repackaged nuclear waste.
Decontamination efforts delayed work for seven weeks, and one worker was exposed to a small amount radiation, but not enough cause health problems, Brown said April 8.
Susan Burke, of the state Environmental Quality Department, says she would have liked to have learned of the accident sooner, but officials have said it wasn't serious enough to require further reporting.
