Chernobyl non è finita: cosa è successo davvero dal 1986 a oggi

Have you ever wondered why reactor 4 exploded on the night of April 26, 1986? The Chernobyl disaster in Ukraine—the worst nuclear accident in history—wasn't just human error, but the failure of a technology that hid a long-ignored design flaw. In this video, we reconstruct the facts with scientific rigor, explaining how the AZ-5 emergency button paradoxically triggered the explosion due to a structural defect in the graphite control rods. But that's not all: we'll also examine the physics of radioactivity to understand how ionizing radiation affects our DNA, analyzing the impact of isotopes like Iodine-131 and Cesium-137. We'll then examine the role of liquidators and the engineering challenge of the New Safe Confinement, the enormous steel arch that today seals the reactor. Finally, we will examine the paradox of the Exclusion Zone, now unwittingly transformed into a unique nature reserve where wildlife thrives despite residual radioactivity and recent geopolitical tensions.
