Sweden’s national body of technical expertise in nuclear weapon matters resides within FOI. Work in this field covers two main areas. One focuses on the security policy aspect, the assessment of the threat posed by nuclear weapons, and this work includes matters concerning disarmament and non-proliferation. The other deals with matters relating to technical verification, in particular how one can detect whether a nuclear warhead has been detonated but also how other agreements on nuclear weapons can be verified.
Where system development and the building of prototypes to measure radioactivity, in particular the noble gases, are concerned, FOI is a world leader. This unit also possesses a unique level of competence in the threat assessment of the risks associated with the proliferation of nuclear weapons.
These activities are largely financed on the basis of assignments from the Ministry of Foreign Affairs and the Ministry of Defence but assignments are also undertaken for SSM (the Swedish Radiation Authority), and CTBTO (the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization), an international organisation that monitors compliance with the Nuclear Test-Ban Treaty.
