The harrowing story of Soviet nuclear testing in Semipalatinsk, Kazakhstan, and the wrangling with its legacy.

It was the summer of 1953. Valentina Nikonchik was outside playing in Semey, a village in eastern Kazakhstan, then part of the Soviet Union. The ground suddenly trembled, and the air filled with a deafening boom that shook Nikonchik to her core. Little did she know that she had witnessed the first detonation at “the Polygon” of a thermonuclear device, a monstrous weapon of mass destruction that released a force equivalent to 400 kilotons of TNT.
West of Nikonchik’s hometown of Semey lies Semipalatinsk, the testing location where the Soviet Union’s nuclear visions were accomplished. A once-thriving region, now a desolate wasteland, has a dark history. In this Central Asian Soviet Republic, the Soviets conducted nearly 400 nuclear tests, blasting a lethal storm of radioactive isotopes into the environment and soil from 1949 to 1989. Even now, the consequences of these tests are still felt, with environmental damage and public health risks ongoing in the area.
At a conference commemorating the ninth anniversary of the Nevada-Semipalatinsk movement, the first anti-nuclear protest movement in the USSR, statistics showing that between 500,000 and 8 million people were directly impacted by the test site’s operations were presented. The detonations, with their tragic and predictable repercussions, represent one of the twentieth century’s major ethical violations. Altogether, the total force of the nuclear explosions at Semipalatinsk equals more than 2,500 Hiroshima bombs. The long-term health effects for the region were harrowing, including an alarming spike in health issues such as miscarriages, birth deformities, and suicides blamed on “unsanitary conditions” in the area by Soviet military scientists in the following decades. What is so disturbing about these dismissals is that the same medical professionals had been performing creeping radiation tests on the villagers for years.
The testing site, despite being uninhabited, is encircled by villages, and the major hub of Semipalatinsk lies just 160 km away. But the testing was kept secret, known only to top Communist Party officials, while anyone who spoke out against the detonations was immediately silenced. Russian scientists confessed that they failed to follow burial and nuclear material protection protocols, as they thought that no one would be in the area. The newly independent Kazakh government officially acknowledged 1,323,000 people as negatively affected by nuclear testing in 1992. However, just 1,057,000 of them received radiation passports, leaving over a quarter of those affected without the requisite documentation. From 2003 to 2017, a $30.5 million reimbursement was intended to give relief to over 700,000 passport holders. Divided between them, a pittance of only only $40 was allocated to each individual each year.

In 1990, a year before independence, the International Physicians for the Prevention of Nuclear War (IPPNW) and Kazakh poet Olzhas Suleimenov’s Nevada-Semipalatinsk Movement banded together and pushed Soviet leader Mikhail Gorbachev’s to issue declaration of a nuclear testing moratorium. Kazakhstan seized the opportunity to declare independence the same year and promptly closed down the infamous Semipalatinsk plant. Then, the nation went further, renouncing its inherited position as the world's fourth-largest nuclear weapons owner, and relinquishing its stockpile.
Despite this, the inhabitants go about their regular lives, seemingly unaware of the danger that surrounds them. They swim and fish in the lakes, graze their herds and pick wild strawberries all while being exposed to the poison lurking in the ground and air. However, the danger does not end there. The area will remain a bleak wasteland for millennia, poisoned with plutonium, strontium, and cesium, unfit for human habitation. Residents continue to graze their animals and collect contaminated scrap metal on the polluted land as the 7,065 square mile region is devoid of barriers, fencing, and warnings reminding people of its radioactive status.
Semey, once a thriving city, has suffered the brunt of the devastation. While acute blasts of radiation produced immediate harm, repeated modest doses of radiation over time can accumulate to cause great damage. The wind on the Kazakh steppe has brought the radioactive fallout to nearby settlements, amplifying the impact. The repercussions of nuclear testing have been passed down to future generations as a result of radiation-induced mutations in the population’s chromosomes. As a result, the region’s life expectancy is seven years lower than the national average due to a rise in the prevalence of cancer, thyroid sickness, and birth abnormalities. Tolkyn Bulegenov, Vice President of Semey Medical University, confirms that “in the zones adjacent to the test site, one can encounter 10 to 15% more malignant thyroid and blood malignancies - hematological blastoma, leukosis, lymphoma, and chronic leukemia - than in other regions of Kazakhstan.”

The late 1980s saw a glimmer of hope for the people of Kazakhstan. As the world was introduced to Gorbachev’s nuclear testing moratorium, the Nevada-Semey movement was born on Kazakh soil with a mission to shut down the Semipalatinsk polygon. Kazakhstan destroyed its inherited weapons testing infrastructure and disposed of the remaining vulnerable nuclear material with the cooperation of foreign partners, including the United States.
On August 29, 1991, President Nursultan Nazarbayev signed the proclamation closing the test site, popularly known as the Polygon, which marked a watershed point in Kazakhstan’s recent history. As part of the Nunn-Lugar Cooperative Threat Reduction Program, the United States collaborated with Kazakhstan between 1995 and 2001 to seal 13 boreholes and 181 tunnels at the test site. From 2012 to 2019, the National Nuclear Security Agency and the Netherlands led two major radiological security operations in Kazakhstan, securing approximately 13,000 radioactive sources from the National Nuclear Center and the Mangystau Atomic Energy Complex. Kazakhstan confirmed its commitment to a nuclear-free world in 2021, in accordance with the Treaty on the Prohibition of Nuclear Weapons.
Kazakhstan’s commitment to disarmament has allowed the nation to serve as an example of a responsible state that has relinquished its nuclear weapons, setting a global precedent for responsible statehood. Kazakhstan has created an environment conducive to the formulation of a multifaceted foreign policy by abandoning its nuclear weapons and closing the world's most extensively used nuclear test site, allowing the country to collaborate with China, Central Asia, Europe, and the United States. While each nuclear-armed state faces unique problems, Kazakhstan’s peaceful approach to disarmament has encouraged many, and its lessons serve as a guide for other countries seeking a similar path.
