Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been ...
Decades-old challenge has researchers seeking new materials for radiation detection
02-19-2008
A more sensitive, more selective and easily deployable radiation detection material is necessary to meet complex 21st century challenges. In the AAAS symposium "Radiation Detectors for Global Security: The Need for Science-Driven Discovery," researchers addressed some of the technical ...
PNNL develops inexpensive portable detection system for rapid, accurate analysis of toxic metals
02-14-2008
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals. The device can provide an accurate blood sample measurement from a simple ...
