Radioactive Source Security Collection

This collection compiles information on the security of radioactive sources from a variety of organisations, both materials that WINS has produced and resources from other institutions, such as the IAEA.

This collection is arranged in seven major subject matter areas:

• Recent Activities
• Comprehensive Radioactive Source Security Management
• Medical Applications
• Industrial Applications
• Alternative Technologies
• Transportation Security
• End-of-Life Management

Just click or scroll down to the section that interests you. Be sure to check back often because we are regularly adding information to these pages.

We Welcome Your Contributions

Please send us your suggestions for additional publications, events, training courses and more that focus on radioactive source security and that would interest your fellow WINS Members, as well as any comments you may have. Together, we can turn these pages into THE home on the web for information on the security of radioactive sources.

Recent Activities

Workshop on Strengthening the Security of Radioactive Sources during Wartime and Violent Civil Unrest
Vienna, Austria, May 2025

The workshop focused on preparing for and responding to nuclear security incidents involving radioactive sources during wartime and violent civil unrest to address threats and minimise the risk of harm. Specifically, the workshop addressed how to plan and prepare for response to nuclear security incidents involving radioactive sources in the context of war and violent civil unrest.

The event report is available here.

Regional Training Course: Secure Transport of Radioactive Material
Bangkok, Thailand, May 2025

Thailand's Office of Atoms for Peace and WINS held a regional training course on the secure transport of radioactive material. The course was comprehensive, covering the fundamental technical material on the secure transport of radioactive sources as well as supporting topics such as the safety-security interface and security culture.

Best Practices for the Secure Transport of Radioactive Material
Online, 25-27 February 2025

The purpose of this online workshop was to share best practices in the secure transport of radioactive material. These discussions served as the basis for the development of a new WINS International Best Practice Guide Security of Radioactive Sources in Transport.

The full event details are available here.

Comprehensive Radioactive Source Security Management

The security of radioactive sources needs to be managed throughout their lifecycle. Competent personnel; adequate financial resources; and carefully planned and implemented policies, processes and procedures are all critical to a comprehensive security programme.

This page highlights WINS International Best Practice Guides, on-demand videos, and past workshops about radioactive source security.

Comprehensive Radioactive Source Security Management

Medical Applications

Ensuring the security of radioactive sources used in medical applications requires careful planning, training and implementation on the part of numerous stakeholders.

WINS has developed an International Best Practice Guide, peer review guidelines, and an infosheet specific to the radioactive sources used in medical applications.

Medical Applications

Industrial Applications

It is crucial to put a robust security programme in place that decreases the likelihood that radioactive sources used in industrial applications will be lost or stolen.

WINS has developed an International Best Practice Guide, peer review guidelines, and an infosheet specific to the radioactive sources used in industrial applications.

Industrial Applications

Alternative Technologies

Given the demonstrated benefits of alternative technologies in reducing the radiological security risk, it is important to stay abreast of the current developments and innovations in the field.

Ongoing research, advancements in new technology, and improvements in existing technologies have made many alternatives to radioactive sources attractive and cost effective.

This page highlights WINS' work to strengthen coordination between international stakeholders in this area as well as guidance on evaluating alternative technologies and success stories.

Alternative Technologies

Transportation Security

Radioactive sources are transported frequently, often across international borders, using various modes of transportation. Because sources are particularly vulnerable when they are being transported, it is crucial that all involved stakeholders communicate effectively with each other and that they plan, implement and exercise effective security measures.

This page includes WINS' International Best Practice Guide on Security of Radioactive Sources in Transport and webinar videos on the subject.

Transportation Security

End-of-Life Management

Measures for implementing appropriate end-of-life measures for radioactive sources should be identified, put in place, and financed before the sources are put into use.

This page includes WINS' International Best Practice Guide on Managing Disused Sources, information on WINS activities on the subject and relevant outside resources.
