Radiophobia, the fear of radioactivity, gets put under scrutiny here, with the film arguing that the dread most people feel about nuclear accidents runs far ahead of what the actual science supports. The starting point is Chernobyl, whose fallout became the reference point for decades of public anxiety about radiation exposure, and the film works through what researchers have actually found in the decades since about health effects, contamination levels, and long-term risk. Scientists and experts lay out the data against the popular narrative, asking why the public reaction to nuclear incidents has stayed so disproportionate to the measured harm. The film treats this gap between perception and evidence as its central problem, tracing how media coverage, government caution, and cultural memory of Hiroshima and Nagasaki combined to build a fear that keeps outrunning the research. It is a case built on numbers and studies rather than dramatic footage, aimed at anyone who has ever wondered whether the popular fear of radiation matches what the science says.
