How do you test a weapon of mass destruction? A weapon whose potential you can only estimate. Since 1945, countries with nuclear capabilities have been coming up with solutions to this problem, but they are not without pitfalls. Traces of the fallout from nuclear testing are found across the world, and testing has directly impacted a plethora of communities. From the original inhabitants of the chosen test sites, to the veterans who worked with the weapons, nuclear fallout has had a variety of different effects. Dr Becky Alexis-Martin is a lecturer in Human Geography at Manchester Metropolitan University. She spoke with James about the communities affected by nuclear weapons testing, the topic of her most recent book: Disarming Doomsday: The Human Impact of Nuclear Weapons Since Hiroshima.
