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:

• Upcoming and 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.

-Discussing certification opportunities offered through WINS Academy
-Learning what opportunities exist and are available to early career professionals

See the event page for more information.

Technical Exchange on Gamma Irradiator Security and Alternative Technologies
Mumbai, India, March 2026

The Irradiation Industries Association of India (IIAI) and the World Institute for Nuclear Security (WINS) successfully conducted a technical exchange that took place directly after the NICSTAR-2026 Conference in Mumbai, India.

Topics discussed included security fundamentals and best practice, cybersecurity and security-by-design for gamma irradiation facilities. An introduction to electron-beam technology was given and followed by a discussion about market conditions in India and the potential for this technology.

See the event page for more information.

Trustworthiness and Reliability Assessments: Current Insider Threat Mitigation Practices of the Radioactive Source Security Community
Online, March 2026

This workshop provided an opportunity for various stakeholders to exchange experience and lessons learned about developing and implementing trustworthiness and reliability assessments in the contemporary workplace.

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.
