This publication, Revision 5 of Physical Protection of Nuclear Material and Nuclear Facilities (INFCIRC/225), is intended to provide guidance to States and their competent authorities on how to develop or enhance, implement and maintain a physical protection regime for nuclear material and nuclear facilities, through the establishment or improvement of their capabilities to implement legislative and regulatory programmes. The recommendations presented in this publication reflect a broad consensus among IAEA Member States on the requirements which should be met for the physical protection of...

Neutron activation analysis (NAA) is a powerful technique for determining bulk composition of major and trace elements. Automation may contribute significantly to keep NAA competitive for end-users. It provides opportunities for a larger analytical capacity and a shorter overall turnaround time if large series of samples have to be analysed. This publication documents and disseminates the expertise generated on automation in NAA during a coordinated research project (CRP). The CRP participants presented different cost-effective designs of sample changers for gamma-ray spectrometry as well as...

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...

This Safety Guide provides recommendations on meeting the requirements established in the IAEA International Basic Safety Standards, for protection of the public against exposure indoors due to natural sources of radiation. Guidance is provided on the application of the requirements for justification and optimization of protection by national authorities in considering control of natural sources of radiation indoors such as radon and radionuclides of natural origin in materials used for the construction of dwellings, offices, industrial premises and other buildings. The Safety Guide provides...

This Safety Guide is intended to assist governments, regulatory bodies, applicants for a licence and operating organizations with a structured approach to controlling radiation exposures of the public resulting from discharges from normal operations of facilities and activities, and with the optimization of protection and safety. More specifically, this publication addresses the process for authorization of discharges from new and modified facilities or activities, and the review of established authorizations. The guidance applies to different types of facilities, which range from nuclear...

The transport of radioactive material is an essential activity worldwide. Both safety and security during transport are matters of national and international importance. This publication is the latest edition of the IAEA Safety Requirements for the Safe Transport of Radioactive Material. It is supported by six IAEA Safety Guides which provide explanation and guidance for the SSR-6 requirements to facilitate harmonized implementation. The SSR-6 Regulations apply to the transport of radioactive material by all modes on land, water, or in the air, including transport that is incidental to the...
