“A New Analysis Triples Plutonium Waste Figures”
“The amount of plutonium buried at the Hanford Nuclear Reservation in Washington State is nearly
Three times what the federal government previously reported, a new analysis indicates, suggesting that a cleanup
To protect future generations will be far more challenging that planners had assumed.”
“The fear is that in a few hundred years [plutonium is radioactive for 24,000 years half-life] plutonium could
Reach an underground area called the saturation zone, where water flows, and from there enter the Columbia River.”
“So far, the cleanup, which began in the 1990’s, has involved moving some contaminated material near the banks of the Columbia to drier locations.
