Restricted Data Declassification Decisions, 1946-2002
The Department of Energy this week released its most recent compilation of all decisions to declassify nuclear weapons-related information.
The new release (pdf), dated 2002, is the eighth and the last in what had been an annual series of such compilations. Unlike the others, however, it was marked “Official Use Only” and was not made publicly available. But DoE released it in response to a Freedom of Information Act request from the Federation of American Scientists.
