ABSTRACT
There was a possibility that the U.S. 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 classified information from the analysis of environmental materials found at these sites. To explore that possibility, the Livermore Forensic Science Center was contacted by a program sponsor to undertake “counterforensic” sampling to evaluate the potential magnitude of the risk to classified technology.
