As many as 11 workers may have ingested or inhaled radioactive contamination at the Plutonium Finishing Plant demolition site at Hanford in southeast Washington state. Ten workers are confirmed to have tested positive and one needs more testing to confirm the results.

Radioactive waste keeps spreading at a demolition site at Hanford. This week, officials have found more contamination on a worker’s boot, on a work trailer and a personal vehicle.

Now, a rental car that’s possibly contaminated has ended up in Spokane. It’s now on a trailer headed back to the Tri-Cities for testing. 


The area and amount of stuff contaminated by radioactive waste at the Hanford Site in southeast Washington state keeps getting bigger.

First it was two cars. Then it was eight. The count is now 14 vehicles that are contaminated with radioactive waste. Half of them are personal cars. One is even contaminated on the inside. 

A new report about the radioactive tank waste at Hanford says the cleanup could take decades longer and cost billions more than estimated. The document, called “System Plan 8”, proposes 11 complex scenarios for how the 56 million gallons of radioactive tank waste could be moved out of those tanks and treated. 


Workers at the Hanford Nuclear Reservation in southeast Washington have been complaining of vapors from radioactive sludge for decades.

This week is the deadline for the State of Washington and the U.S. Department of Energy to reach an agreement on how to clean up radioactive tank waste at the Hanford Nuclear Reservation. The two sides can’t agree on a timeline.

When it comes to the many underground tanks at Hanford filled with radioactive sludge, just how much do we know? U.S. Senator Ron Wyden says not enough.

Over the last several years, Hanford Nuclear Reservation managers have mishandled barrels and boxes of hazardous and radioactive waste in the central part of the site.

For eight months, a federal contractor at the Hanford Nuclear Reservation failed to check some single-shell radioactive waste tanks for the buildup of hydrogen gas.
