3. Nicolas Freeling, Gadget (New York: Coward-McCann and Geoheghan, 1977), see particularly pp. 43–8, 63–7, 76–80, 90–93, 101–110, 226–31. Freeling (and Zimmerman, his physicist collaborator), have anticipated many of the problems facing nuclear terrorists, including criticality testing, criticality accidents, remote arming and detonation, and evasion of detection. The ‘computations’ to be found on pages 44, 45, 63, 64 and 65 must not be taken seriously.
