The 1986 Chernobyl disaster, resulting from human error during a reactor test, was the largest nuclear accident in history. Engineers, led by Anatoly Dyatlov, conducted a flawed test that compromised safety systems, leading to an explosion and the release of radioactive materials, including uranium.

Approximately 600 workers were present at the site; 134 developed acute radiation sickness, and 28 died later. The disaster prompted the evacuation of thousands within a 30-kilometre radius and caused an estimated 20,000 cases of thyroid cancer due to radioactive iodine exposure.

Cleanup efforts involved 600,000 'liquidators,' many of whom suffered long-term health issues from radiation. Despite the disaster's severity, nuclear energy remains a low-carbon energy source, requiring only 100 grams of uranium to generate 11,000 kWh.

Comparatively, coal and gas produce significantly higher CO2 emissions. The Chernobyl disaster led to improved nuclear safety protocols, and no nuclear accident of similar scale has occurred since.
