Researchers from North Carolina State University have developed a new technique that uses existing technologies to detect potential airborne radiological materials in hours instead of days.
“We wanted a rapid way of detecting radiological aerosols that are usually associated with the production of dirty bombs or other radiological weapons,” says Joseph Cope, a Ph.D. student and fellow with the Consortium for Nonproliferation Enabling Capabilities (CNEC) at NC State and lead author of a paper on the work.
At present, emergency responders who are characterizing potential radiological risk need to take an air sample and ship it to a radiochemistry lab after preliminary screening analysis. The process means it can take days or weeks to get quality results that authorities can use to make informed decisions.
“We’ve found a way that repurposes existing tools, and can give first responders quality information in as little as two hours,” Cope says.
