Detection of nuclear security events involving nuclear and other radioactive material out of regulatory control is an important challenge facing States. Timely detection of this material can reduce the risk of it being used in criminal or intentional unauthorized acts. This publication provides guidance for States on planning, implementing and evaluating nuclear security detection systems and measures at State borders. Special consideration is given to designated points of entry and exit and border areas. National competent authorities such as the border guard, customs authorities, national or local law enforcement agencies and regulatory bodies will find this guidance useful for developing, designing, implementing, and sustaining detection systems and measures at State borders.

"This publication provides recommendations to a State for the nuclear security of nuclear or other radioactive material that has been reported as being out of regulatory control, as well as for material that is lost, missing or stolen but has not been reported as such, or has been otherwise discovered. It includes recommendations for the detection and assessment of alarms and alerts and for a graded response to criminal or unauthorized acts with nuclear security implications involving nuclear or other radioactive material out of regulatory control. The recommended actions cover the confirmation of a credible threat, assessment and interdiction of an attempted act and response to a nuclear security event."--P. [4] of cover.

"This IAEA Nuclear Security Series publication provides nuclear security fundamentals, recommendations, and supporting guidance for Member States to assist them in implementing new nuclear security regimes, or in reviewing and if necessary strengthening existing ones. The IAEA Nuclear Security Series also serves as guidance for Member States with respect to their activities in relation to binding and non-binding international instruments. The Nuclear Security Fundamentals are the primary publication in the IAEA Nuclear Security Series, and set out the objective of an effective national nuclear security regime and essential elements of such a regime. They are aimed at national policy makers, legislative bodies, competent authorities, institutions, and individuals involved in the establishment, implementation, maintenance or sustainability of a State's nuclear security regime."--Provided by publisher.

The Global Nuclear Detection Architecture (GNDA) is described as a worldwide network of sensors, telecommunications, and personnel, with the supporting information exchanges, programs, and protocols that serve to detect, analyze, and report on nuclear and radiological materials that are out of regulatory control. The Domestic Nuclear Detection Office (DNDO), an office within the Department of Homeland Security (DHS), coordinates the development of the GNDA with its federal partners. Performance Metrics for the Global Nuclear Detection Architecture considers how to develop performance measures and quantitative metrics that can be used to evaluate the overall effectiveness and report on progress toward meeting the goals of the GNDA. According to this report, two critical components are needed to evaluate the effectiveness of the GNDA: a new strategic plan with outcome-based metrics and an analysis framework to enable assessment of outcome-based metrics. The GNDA is a complex system of systems meant to deter and detect attempts to unlawfully transport radiological or nuclear material. The recommendations of Performance Metrics for the Performance Metrics for the Global Nuclear Detection Architecture may be used to improve the GNDA strategic plan and the reporting of progress toward meeting its goals during subsequent review cycles.

This publication provides guidance for States on planning, implementing and evaluating nuclear security detection systems and measures at State borders.

Radiological crime scene management is the process used to ensure safe, secure, effective and efficient operations at a crime scene where nuclear or other radioactive materials are known, or suspected, to be present. Managing a radiological crime scene is a key part of responding to a nuclear security event. Evidence collection at radiological crime scenes may share a wide range of characteristics with that at conventional crime scenes, such as evidence search patterns, geographical scene modelling and evidence recording, whether or not explosives are involved. This publication focuses on the framework and functional elements for managing a radiological crime scene that are distinct from any other crime scene. It assumes that States have a capability for managing conventional crime scenes.

The IAEA Safety Glossary defines and explains technical terms used in the IAEA Safety Standards and other safety related IAEA publications, and provides information on their usage. The 2018 Edition of the IAEA Safety Glossary is a new edition of the IAEA Safety Glossary, originally issued in 2007. It has been revised and updated to take into account new terminology and usage in safety standards issued between 2007 and 2018. The revisions and updates reflect developments in the technical areas of application of the safety standards and changes in regulatory approaches in Member States.
