Notes
An earlier version of this article was presented at the Workshop on Science and Modern Technology in Safeguards held in Arona, Italy, from October 28–31, 1996, and sponsored by the European Safeguards Research and Development Association, the Joint Research Centre of the European Commission, and the Institute of Nuclear Materials Management. The article benefited greatly from comments received from Clay Moltz and two anonymous reviewers. Research support was provided through a Summer Research Award from the University of Oregon.
