To be, or not to WMD?
Nuclear issues don’t need to be rocket science… well, at least not all of them.
Welcome to CBRN 101!
Trying to learn more about chemical, biological, radiological, and nuclear issues shouldn’t be that difficult.
On this website, you’ll find a collection of great resources to learn what you need to get started.
Have a look around!

Online Short Courses
Looking for some guidance on how to navigate the field, or put your knowledge to the test? Need some certificates to add to your CV?
We hear you.
From nuclear energy and safeguards, to broader disarmament and arms control initiatives, these free eLearning Courses cover a wide array of topics.
… and between international organisations, think tanks and academic institutions, have your pick of what suits your interests the best.
International Organisations
The EU Non-Proliferation and Disarmament (EUNPDC) eLearning Course covers key aspects of the EU’s non-proliferation and disarmament agenda, with a focus on arms control, non-proliferation, and the disarmament of both conventional and unconventional weapons.
The International Atomic Energy Agency (IAEA) hosts a Learning Management System with a primary focus on nuclear safety and security, nuclear technology and applications, as well as safeguards and verification.
The United Nations Office for Disarmament Affairs (UNODA) provides eLearning courses at various proficiency levels, on themes ranging from basics of disarmament to gender and humanitarian dimensions, as well as emerging technologies.
Think Tanks & Academia
The Nuclear Threat Initiative (NTI) offers a variety of research and materials, including tutorials on CBRN security, nuclear testing and international treaties, delivery systems, or even the U.S. nuclear budget.
The PIR Center is a Russian NGO, providing an online short course on the pillars of the nonproliferation regime.
The Stimson Center South Asia Program‘s Strategic Learning initiative has developed a course on Missile Technology in South Asia, exploring missile types, arsenals and missile defense systems across China, India, and Pakistan.
The Vienna Center for Disarmament and Non-Proliferation (VCDNP) and the James Martin Center for Nonproliferation Studies (CNS) also offer a short course on nuclear weapons and technology, their international regulation and monitoring.
Datasets & Simulations
So, you passed that honeymoon phase of learning about those big CBRN issues. What can be done to keep the neutrinos flying?
a) Crunch the numbers yourself
b) Or – in case you are a visual learner – look at some explosions!
From scientific articles to PC games, why not try out something new?
