Belarusian Academy of Sciences

The Belarusian Academy of Sciences is presented through the scientists and the Institute for Nuclear Energy who worked under its institutional umbrella during the Chernobyl disaster. Their measurements and reports made the spread of contamination legible, but their testimony also records how little scientific authority could compel officials to act. The Academy’s significance in these accounts lies in that tension: its researchers could detect and document danger, yet information was obstructed, protective measures were delayed, and the scientists themselves faced restrictions and intimidation.

Institutional setting and scientific work

The testimonies identify the Institute for Nuclear Energy of the Belarusian Academy of Sciences as a center for research and radiation assessment. Marat Filippovich Kokhanov is identified as the Institute’s former chief engineer; Valentin Alekseevich Borisevich as a former head of one of its laboratories; and Vasily Borisovich Nesterenko as its former director. These professional roles place the Institute within the Academy’s scientific structure, while the accounts follow its staff into contaminated areas and into conflict with regional and central authorities.

The work described was practical as well as analytical. On his first trip into the Zone, Kokhanov measured forest background radiation at five to six times the levels recorded on roads or fields. In several villages, thyroid measurements among adults and children reached one hundred to two hundred times the allowable dosage, and sometimes three hundred times. The group also tested breast milk and food. An exposed child playing in a sandbox, radioactive milk, and uncovered salami and margarine displayed in village stores turned radiation from an abstract reading into an everyday hazard. The investigators tested an egg and salami and concluded that the food was radioactive byproduct, not food fit to eat.

Measurements against official reassurance

Nesterenko’s account shows how technical warnings met a political system already controlling the flow of information. Trying to reach Nikolai Slyunkov, then General Secretary of the Central Committee of the Communist Party of Belarus, he found that government telephone calls went dead as soon as he began discussing the accident. After roughly two hours he got through and warned that the radioactive cloud was moving toward Belarus. He urged immediate iodine prophylaxis and evacuation of people and animals within 100 kilometers of the station. Slyunkov replied that he had received reports of a fire that had been put out.

When Nesterenko later met Slyunkov, he described what he had seen and argued that people had to be saved. The official countered that Institute staff were frightening the public by carrying dosimeters, invoked assurances from Moscow, and pointed to the government commission and military response at the station. Nesterenko’s account sets those reassurances against the scale of the contamination: thousands of tons of radioactive material, 450 types of radionuclides, and an estimated release equivalent to 350 atomic bombs dropped on Hiroshima. The dispute was not simply over competing readings. The scientists sought to make radiation’s physical consequences the basis for action, while officials treated alarming information as a threat to public order.

Reports, mapping, and pressure on researchers

After officials stopped receiving him, Nesterenko sent letters and formal reports through the chain of command, including maps and figures. He assembled four folders of 250 pages each, made duplicate copies, and hid one set at home with his wife while keeping another at the Institute. The precautions proved warranted: after one trip, the folders in his office had disappeared. The Institute continued making field visits and produced the first map of contaminated areas; Nesterenko recalled the whole south marked red.

The institution’s ability to measure and communicate was itself vulnerable. Radiation-measuring equipment was confiscated without explanation, and Nesterenko received threatening calls at home warning him to stop frightening people. He described pressure and intimidation directed at scientists in the Institute. His account makes the map and the missing folders more than administrative details: they represent evidence painstakingly assembled, preserved against possible disappearance, and then placed at risk by the very authorities who could have used it.

Professional duty and institutional limits

Kokhanov described a different but related obstacle: scientists knew what their measurements meant, yet continued to obey orders and remain silent. He recalled asking supervisors what to do and being told to take measurements and watch television. On television, Mikhail Gorbachev reassured the public that immediate measures had been taken. Kokhanov, an engineer with twenty years of experience, believed that all living things should leave the area, but he and his colleagues continued their assigned work. He attributed their silence not chiefly to fear of losing Party membership but to their faith in the Soviet system and its ideals. In his interpretation, this faith helped explain why technically informed people could carry out orders without publicly challenging them.

That conflict between professional knowledge and institutional obedience also shaped the costs of the work. Kokhanov connected the later collapse of faith among some colleagues with heart attacks and suicides, and understood Professor Legasov’s suicide as a sign of what happened when belief in the system failed. Borisevich, meanwhile, described a break in his own sense of vocation: a physicist who had expected to devote his life to physics began wanting to write about science’s power over human life and the possibility that physics and mathematics could become a new dictatorship. Together, these reflections show the disaster reaching beyond measurement into the scientists’ understanding of their work and the authority they had once trusted.

Significance in the disaster record

The Academy’s institutional presence in these accounts is neither a simple story of scientific rescue nor a portrait of a unified organization acting with one voice. Researchers measured contamination, interpreted the results, made maps, and tried to warn decision-makers; their reports and professional standing did not ensure that the public received protection or accurate information. The Institute’s evidence competed with political reassurance, while its equipment, communications, and records could be blocked or seized.

The testimonies therefore make scientific knowledge both concrete and precarious. A dosimeter could register danger in a forest, a thyroid measurement could reveal exposure in children, and a map could mark the contaminated south, but none of those instruments alone could secure evacuation or disclosure. The Belarusian Academy of Sciences matters in this account as the setting for expertise whose findings carried urgent public consequences—and as the institutional world from which scientists confronted the limits imposed on acting upon what they knew.
