The compendium at hand will be used both within an outside Sweden as course material. It is partly a result from the work done by TKM (Training and knowledge management), which is a working group within Esarda (European Safeguards Research and Development Association) that on a yearly basis educates students from all over Europe. The intention is that the material shall be used in conjunction with courses in former Soviet states as well as in other international associations. In Sweden, the compendium is used in courses given at Uppsala University. This material is made available at SKI:s webpage ( http://www.ski.se ) in both an English and a Swedish version (SKI report nr:2007:45).
