Nuclear forensics is a technical measure to analyse and collate samples of illegally used nuclear materials, etc., to clarify their origins, routes, etc. and contribute to criminal identifications. Close collaboration with police and judicial organizations is essential. The national response framework is being built up with international cooperation. Discussions on promoting technical capability and regional cooperation are presented.

Nuclear Forensics capability has been developed under the international collaborations. For its effective function, technical development in analysis of seized nuclear materials as well as the institutional development in comprehensive response framework are required under individual national responsibility. In order to keep the "chain of custody" in the proper operation of sample collection at the event scene, radiological analysis at the laboratory, storage of the samples, and further inspection and trial, close cooperation and information sharing between relevant organisations are essential. IAEA issues the Implementing Guide to provide the model action plan and assists individual national development. International cooperation for the technical improvement and awareness cultivation is promoted. Examples in such national developments will be introduced and prospective technical/institutional prerequisite for nuclear forensics response framework will be studied.

Nuclear forensics is effective measure for strengthening nuclear security through the analysis of origin and characteristics of nuclear materials or radio-isotopes collected at the crime scene inspections. In the development of nuclear forensics laboratory/library, "Chain of Custody" should be kept in mind on the view point of juridical process. Each nation should develop own national response plan to stipulate the framework for integrated nuclear forensics activities. Good practices for stipulating national frameworks for nuclear forensics are investigated in advancing nations such as US, EU and Canada. Issues and measures are proposed aiming at improving its framework.
