The Semipalatinsk Test Site: Kazakhstan's Nuclear Tragedy
The Semipalatinsk nuclear test site (often called Semey Polygon) was created by decision of the Council of Ministers of the USSR on August 21, 1947 and was one of the greatest nuclear test grounds in human history. It hosted the first tests of nuclear weapons created in the USSR. The main test site was located south of the Irtysh River Valley, about 130 km west of the city of Semipalatinsk (Semey)
Background
The authorities chose Kazakhstan because of its scale and pristine steppes, which were ideal for testing atomic bombs. Before conducting these tests, it was necessary to solve a whole range of complex scientific and practical tasks: to evaluate the possibility of creating a nuclear bomb and substantiate its design scheme; to organize the production of components of a "new" type of weapon, to build new industrial enterprises; to assemble all the structural components of the bomb into a single whole. For 40 years, from 1949 to 1989, 473 nuclear explosions were carried out at the Semipalatinsk test site, including 90 aerial, 26 ground, and 354 underground. In addition to nuclear tests, 175 chemical explosions were carried out here, 44 of them with charges of more than ten tons. Even if at that time the test site served as a place where atomic bombs could be tested. This decision had a profound impact on Kazakhstan, causing significant economic, environmental, and social problems. Even now, many people and places are suffering from the aftermath of this nuclear test site.
Economic Decline and Poverty:
Radioactive clouds from ground-based and aerial explosions, as well as gaseous fractions from underground testing, spread beyond the landfill, polluting the adjacent regions of Kazakhstan. It was difficult to engage in animal husbandry on such polluted land. And in those days, it was almost the only income for residents in the regional districts. Moreover, since it was impossible to sow grain on such land, the lack of resources led to poverty. Additionally, people couldn't pay taxes due to a lack of financial resources. The health of the residents also deteriorated, and they were unable to work. As a result, people could not pay taxes due to a lack of financial resources and due to health problems.
High Costs of Healthcare and Social Services:
Radiation exposure has led to chronic health problems for the local population, including cancer, birth defects, immune diseases, and genetic mutations observed decades later. These health problems increase government spending by diverting funds from other economic priorities, such as infrastructure or education. In addition, residents of the most polluted areas received compensation for living in hazardous areas, which further increases the financial burden on the state.
Social Impacts:
First social impacts started to be noticed in 1992 when scientists confirmed the presence of new peculiar diseases previously identified in people living around the nuclear test site. These health problems were skin lesions, hair disorders, pathological changes in the cardiovascular system, and a weakening of the immune system. It was noted that exposure to radiation causes a more serious process of premature ageing of the body, an increase in cancer, and suicide cases among the residents. These health problems were not temporary. Despite the passage of time, residents continue to suffer from various diseases caused by radiation. The most common diseases are radiation sickness and oncological diseases. Even small doses of radiation significantly increase the risk of developing cancer.
There were also demographic problems due to widespread diseases; many females could not give birth to children, and if they did give birth, the children were born unhealthy and very weak. As a result, in 1997, almost 49% of babies born at the Semipalatinsk Perinatal Centre suffered from birth defects or serious health problems.
The consequences of the Semipalatinsk Test Site for today's Kazakhstan
As mentioned earlier, the landfill has led to many economic and social problems. However, some of the consequences are still ongoing. If we talk about the economy, now people who live in the Abai region do not suffer from poverty, and the Abai region is getting more developed each year.
In July 2023, President of Kazakhstan Kassym-Jomart Tokayev signed the Law "On the Semipalatinsk Nuclear Safety Zone", aimed at ensuring nuclear and radiation safety in Kazakhstan during the rehabilitation of the territory of the former Semipalatinsk nuclear test site. This lets us know that the government will more and more prevent the problems of the former Semipalatinsk, now the Abai region. However, health problems among the residents are still there. Even though almost 40 years have passed since the closure of the nuclear test site, people still have health problems, not to mention how many there were during the nuclear explosions. The most common diseases due to radiation exposure are called radiation sickness.
The Semipalatinsk test site was a great blow to the Kazakh land and the Kazakh people. One test site has led to many problems that still affect people's lives and has left a big scar on the residents of the Abai region. What is more, the government is still providing financial assistance to solve social problems like health problems. However, many economic problems have already been solved, and now the region is developing every day. Overall, the Semipalatinsk test site will remain as an economic and social tragedy in the history of Kazakhstan for Kazakh people.
