ABSTRACT
There was a possibility that the US gaseous diffusion facilities at Portsmouth, Ohio, and Paducah, Kentucky, would be subject to international inspections for safeguards and accountability purposes. The question arose of whether an inspector with a covert agenda could surreptitiously learn classi–ed information from the analysisof environmental materials found atthese sites. To explore that possibility, the Livermore Forensic Science Center (FSC) was contacted by a program sponsor to undertake “counterforensic” sampling to evaluate the potential magnitude of the risk to classi–ed technology.
