"It's sort of like using infrared goggles to see heat signatures in the dark, except this is underground." PNNL and CHPRC implemented a state-of-the-art approach to monitor the process of remediating residual uranium at Hanford's 300 Area.

An International Atomic Energy Agency effort, chaired by PNNL's Mike Truex, will help inform the process for achieving successful end states at contaminated sites worldwide.

The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature.

PNNL scientists served as lead guest editors for a special issue of the Journal of Applied Radiation and Isotopes.

Once cooled, this molten glass can trap radioactive waste for thousands of years.

Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.

April 26 marks the 31st anniversary of the explosion at the Chernobyl Nuclear Power Plant's Unit 4 reactor. Battelle researchers at PNNL were involved in an international consortium to look at long-term safety and containment of Unit 4. T
