The presence of critical radioactivity in environments everywhere on the planet is owed to mid-twentieth-century atomic weapon tests as well as to the ongoing use of nuclear energy and concomitant accidents. While the notion of the “Nuclear Age” evoked the idea of a legacy from the past only a few years ago, we currently face a much different nuclear situation amid ongoing geopolitical shifts and ruptures.
