All Tested Energy Dept. Workers Pass Polygraph

All 800 nuclear scientists and security workers at the Energy Department subjected to polygraph exams this year passed the exams, the agency’s director of counterintelligence says.

About 20% of the employees showed physiological responses that indicated some “deception” when questioned about unauthorized contacts, Edward J. Curran told the Washington Post.

But he said all of those people passed when given a chance to answer the question again after being allowed to explain a minor transgression.

The Energy Department had a polygraph program for officials in highly sensitive positions in nuclear weapon programs, but Congress ordered it greatly expanded after claims of espionage at the Los Alamos National Laboratory.
