Chernobyl liquidators return for anniversary

Ahead of the 40th anniversary of the Chernobyl disaster, former liquidators have returned to the site. These individuals, including soldiers, firefighters, engineers, miners, and medics, were summoned from across the USSR to clean up the world's worst nuclear accident following the April 26, 1986, explosion and fire. Their mission involved confronting an invisible and deadly enemy in the form of massive radiation contamination. The anniversary serves as a somber reminder of the human cost and long-term environmental impact of the catastrophe.
