This revision provides guidance to States and their competent authorities on how to establish or improve, implement, maintain and sustain the elements of the nuclear security regime related to radioactive material, associated facilities and activities, with particular emphasis on the development of regulatory requirements. The publication applies to the security of radioactive material in use or in storage, as well as associated facilities and associated activities, and assists Member States in their regimes against unauthorized removal of the radioactive material or sabotage performed with the intent to cause harmful radiological consequences.

There are concerns that terrorist or criminal groups could gain access to high activity radioactive sources and use these sources maliciously. Based on extensive input from technical and legal experts, this implementation guide sets forth guidance on the security of sources.

This publication presents the proceedings of an international conference in the field of nuclear security. The conference was convened to foster the exchange of practices and experiences related to the security of radioactive material under regulatory control in use, transport and storage, and the detection of nuclear and other radioactive material out of regulatory control. The conference provided a forum for Member States to share their experiences, difficulties, and lessons learned during the implementation of IAEA Nuclear Security Series No. 13, Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities (INFCIRC/225/Rev.5). The publication contains the President's summary of the conference, statements from the opening and closing sessions, and an outline of the conference programme. The attached CD-ROM contains the full conference programme, the list of conference participants, and a selection of papers and presentations from the conference.

Nuclear security culture is an important component of an effective nuclear security regime, as it serves as a tool to improve the performance of the human component at nuclear facilities and organizations to counter both insider and outsider threats. Security culture connotes not only the technical proficiency of the people but also their awareness of security risks and motivation to follow established procedures, comply with regulations and take the initiative when unforeseen circumstances arise. A workforce made up of individuals who are vigilant, who question irregularities, execute their work diligently and exhibit high standards of personal and collective behaviour is able to achieve effective nuclear security. Building upon this understanding of the importance of a strong nuclear security culture, this publication provides practical guidance on how to implement a systematic nuclear security culture enhancement programme.
