RICHLAND, Wash. (AP) - Cleanup workers are back on the job today
on the Hanford nuclear reservation, where radioactive contamination
prompted a safety review.

The tritium contamination incident near the Columbia River comes
on the heels of reports that an employee had falsified records.

Washington Closure Hanford spokesman Todd Nelson says about
1,000 employees who went to safety training Wednesday are
back at work Thursday.

The company says it does not believe any workers health was
harmed by the tritium contamination that was discovered earlier
this week.

Washington Closure and Energy Department officials are working
on a decontamination plan for the tritium, which was produced at
Hanford from 1949 to 1952. The radioactive isotope is used in
hydrogen bombs.

Energy Department spokeswoman Colleen French says the agency
wants to ensure that employees are safe and that the environment is
protected.
