Tracing uranium's past, and how it intersects with our understanding of other radioactive elements, this book aims to disentangle our attitudes and to unpick the atomic mindset. Chain Reactions looks at the fascinating, often-forgotten, stories that can be found throughout the history of the element. Ranging from glassworks to penny stocks; medicines to weapons; something to be feared to a powerful source of energy, this global history not only explores the development of our scientific understanding of uranium, but also shines a light on its cultural and social impact. By understanding our nuclear past, we can move beyond the ideological opposition to atomic technology and encourage a more nuanced dialogue about whether it is feasible - and desirable - to have a genuinely nuclear-powered future.
