April 26, 1986

April 26, 1986, is the date of the Chernobyl reactor catastrophe: at 1:23:58, explosions destroyed the reactor in Energy Block 4 of the Chernobyl Nuclear Power Station. The blast became the largest technological disaster of the twentieth century, but the date’s significance in Voices from Chernobyl lies not only in the sudden destruction. It also marks the beginning of a prolonged emergency whose contamination, displacement, and health consequences continued to shape life long afterward.

The reactor’s destruction

The accident occurred at Chernobyl, south of Belarus. The historical note observes that Belarus had no nuclear power stations of its own; the functioning stations nearest its borders were Soviet-designed RBMK plants, including Chernobyl. The date therefore names a disaster that began beyond Belarus but fell with exceptional severity on the country and its people.

The book’s opening framing calls it the worst nuclear reactor accident in history and says contamination reached as much as three quarters of Europe. Its historical account identifies the explosions at 1:23:58 as the moment the reactor was destroyed. That precise time gives the catastrophe a sharp chronological point of origin, even as the effects described in the book resist being confined to a single moment.

Belarus and the scale of the aftermath

For Belarus, a country with a population of 10 million, the accident became a national disaster. The historical note sets its losses beside those of the Second World War: the Nazis destroyed 619 Belarusian villages along with their inhabitants, while Chernobyl led to the loss of 485 villages and settlements. Seventy of those settlements were permanently buried underground. The comparison makes visible both the scale of the destruction and its distinct character: a disaster not measured only in immediate deaths, but also in places rendered uninhabitable and communities removed from the landscape.

The account gives the human burden in stark proportions. During the war, one in four Belarusians was killed; in the aftermath of Chernobyl, one in five lived on contaminated land. That meant 2.1 million people, including 700,000 children. In Gomel Region and Mogilev Region, the areas described as most affected, mortality exceeded births by 20 percent. Radiation is identified as the leading factor among those contributing to Belarus’s depopulation.

The historical note also records the physical spread of contamination: 50 million curies of radionuclides were released into the atmosphere, 70 percent of them falling on Belarus. Cesium-137 contamination above one curie per square kilometer affected 23 percent of Belarusian territory. These figures give the date a reach far wider than the destroyed reactor building: the event’s consequences were registered across land, settlement, and population.

A date that opens into testimony

Voices from Chernobyl presents April 26 not as a self-contained historical episode but as the point from which many people’s accounts begin. Journalist Svetlana Alexievich interviewed hundreds of people affected by the meltdown, including citizens, firefighters, and those called in to clean up the disaster. Their monologues convey fear, anger, and uncertainty that did not end with the explosions.

The date thus holds two scales of time in tension. At 1:23:58, the reactor’s destruction is a sudden, specific event; the Belarusian figures describe losses accumulating across years and generations. In the book’s structure of personal testimony, April 26 is both a fixed historical marker and the beginning of lives lived with consequences that remained unresolved.
