Chernobyl Disaster Coverup

SIGNIFICANCE: After the explosions in 1986 at the Chernobyl nuclear power plant, the Soviet government initially attempted to cover up history’s worst nuclear accident; however, surveillance from outside the country compelled its leaders to acknowledge the full scope of the disaster.

DATE: April 26, 1986

PLACE: Chernobyl station, Ukraine, Soviet Union

On Saturday, April 26, 1986, one of the most frightening catastrophes of modern industrial history occurred at the Chernobyl nuclear plant in what was then the Soviet republic of Ukraine. Two explosions destroyed a building housing a reactor, sending flames one hundred feet high and releasing a heavily radioactive plume in the air. Over the next ten days, gases streamed out of the ruins, spewing deadly radioactive material over vast areas of the Soviet Union and Western Europe. Over 100,000 people were evacuated from the area around the accident, including eighteen thousand who were sent to clinics for examination. The official immediate reported loss of life was only thirty-one persons, but many more suffered from various forms of radiation sickness or birth defects, and experts predicted that, over time, the total human casualties would eventually number in the thousands.

The accident resulted from improper procedures that had been carried out by an inexperienced team testing a voltage-regulating system on a turbogenerator. However, the problem went beyond mistakes of personnel. The Chernobyl reactor, known as a RBMK-1000 type, was by Western standards an inferior 1950s design with inherently dangerous features. One particularly serious safety defect was its lack of a protective containment structure.

The Soviet government’s public reaction to the accident seriously undermined the credibility of Mikhail Gorbachev’s administration and raised doubts about his new policy of glasnost (or openness). The government initially deceived not only the outside world but its own people, to the serious detriment of those living near the site of the accident. Although it was aware of what had happened within hours, the government kept its news out of the press for almost three days. Western embassies were not notified until the radiation cloud reached Sweden on the Monday after the accident. Soviet press releases contained information that was incomplete, inaccurate, and designed to downplay the magnitude of the damage. Radiation levels published by the press were 1 percent or less of what authorities knew to be their true levels.

Fearing panic and perhaps a damaging public reaction, the government reported that everything was under control. The respected Soviet physicist and political dissident Andrei Sakharov was approached by government agents pretending to be chance passers-by. They asked him about Chernobyl, secretly videotaped his responses, and then broadcast an edited version of his interview to reassure an anxious public. Meanwhile, the lack of reliable information from the government fed rumors throughout the country that in many instances portrayed events as being even worse than they really were.

Gorbachev himself waited more than two weeks before he reported to the public on television. The thrust of his report was a bitter attack against the US news media, whom he accused of spreading “lies—very shameless and malignant lies.” Subsequently, the Soviet government changed its tactics and revealed details of what had happened at a special conference of the International Atomic Energy Agency in August. The economic and political damage caused by the Chernobyl accident contributed significantly to the Soviet Union’s collapse five and a half years later.

In 2021, the Ukrainian security service claimed that documents existed that indicated Soviet knowledge of the dangerous status of the Chernobyl plant years before the accident occurred. After unsealing archived Soviet security agency reports, the Ukrainian government announced that multiple incidents had occurred at the plant, including the release of radiation, in 1982 and 1984 that the Soviet government had been aware of but had not disclosed publicly. The following year, HBO's documentary Chernobyl: The Lost Tapes included archival footage and interviews that commentators alleged provided further insight into the extent and impact of the cover-up operation.
