The clean-up of Chernobyl

This episode of Witness History recounts the harrowing aftermath of the Chernobyl nuclear disaster on 26 April 1986, focusing on the efforts of the 'liquidators'—military personnel, workers, and volunteers—who were sent into the most contaminated zones to clean up the site. Narrated by Timo Callaghan, the story centers on Yuri Skoletsky, a Soviet military radiological officer who assessed the health of these workers. Despite the extreme danger—radiation levels reaching 1,000 roentgens on the reactor roof—thousands of men volunteered, driven by a sense of duty and a fivefold salary increase. With no proper protective gear, they wore improvised lead-lined suits and worked in shifts of just two minutes. The episode highlights the tragic long-term health consequences, including spikes in leukemia and thyroid cancer among liquidators and children exposed at the time. Though initial medical checks showed no overexposure, decades later the toll became undeniable, with estimates of 4,000 to over 100,000 deaths linked to the cleanup. The episode underscores both the bravery and the human cost of one of the world’s largest nuclear disasters.
