The official death toll of the 1986 Chernobyl accident, ‘the worst nuclear disaster in history’, is only 54, and stories today commonly suggest that nature is thriving there. Yet award-winning historian Kate Brown uncovers a much more disturbing story, one in which radioactive isotopes caused hundreds of thousands of casualties, and the magnitude of the disaster has been actively suppressed. For years after, Soviet scientists, bureaucrats and civilians were documenting staggering increases in birth defects, child mortality, cancers and other life-altering diseases. Worried that this evidence would blow the lid on the effects of radiation release from Cold War weapons-testing, scientists and diplomats from international organizations, including the UN, tried to bury or discredit it. Brown also encounters many everyday heroes, often women, who fought to bring attention to the ballooning human and ecological catastrophe, and adapt to life in a post-nuclear landscape, where the dangerous effects of radiation persist today. Based on a decade of archival and on-the-ground research, Manual for Survival is a gripping historical detective story that brings to light the real consequences of Chernobyl – and the plot to cover them up.
