On April 25, 1986, the worst nuclear disaster in history occurred at the Chernobyl nuclear power plant in Ukraine, then a part of the Soviet Union.
The disaster happened due to a critical flaw in the reactor design, as well as errors made by workers at the plant. On the day of the disaster, the workers were attempting an experiment which involved running the plant while shutting down all the emergency safety systems, leaving the reactor in an extremely unstable state. This would’ve granted one of the head managers a medal, so the previous shift were rushed. Several mistakes were made during the test, leading to explosions and a fire at the plant. This fire directly affected many wires, which led to the coolant being off. This led to an amount of radioactive material larger than that of the bombings of Hiroshima and Nagasaki being released and carried across Europe from wind. Radioactive emissions continued for 10 days after the initial accident.
Initially, Soviet authorities were slow to release information about what had happened, wanting to prioritize the interests of the government over the lives of its people. News was also not reported to the government in full, as the head of the plant wanted to downplay the incident. However, the radiation was soon detected by scientists inside and outside the Soviet Union, forcing them to disclose more information.
The human cost attached to Chernobyl is almost unimaginable in the sheer number of people affected. Reports made since the disaster attribute about 5,000 thyroid cancer diagnoses to it. Of course, there’s no way to arrive at the exact number of deaths and cancer cases caused by the radiation. And despite a relatively low number of deaths, the amount of people affected in some way numbers in the hundreds of thousands. 600,000 workers, who were called liquidators, were exposed to varying levels of radiation in the effort to clean up the plant and store radioactive material long-term. Thousands of young conscripts were used to clear up dangerous waste. The initial spread of the radioactive material across Europe led to the evacuation of hundreds of thousands of people. But still, hundreds of thousands more were not able to move and remained in the path of the radiation. Resettlement of previously radioactive areas is an ongoing process. And lastly, many people affected have worse mental health outcomes, including higher rates of depression and anxiety, as well as a perceived lower life expectancy.
Today, The Chernobyl nuclear disaster led to changing attitudes regarding safety in the nuclear power industry. Reactor designs and operating norms changed. Chernobyl is also attributed as being a major factor in the fall of the Soviet Union, as it made the public distrust the government, which first said nothing was wrong. It also showed weakness of the Soviet science program. Furthermore, Chernobyl is a testament to the ability of nature to thrive, even in literal wastelands. Despite some trees and animals dying or experiencing unwanted changes, there has been a positive increase in biodiversity thanks to the area being relatively untouched by people after the disaster. Due to the lack of human activity, the radioactive zone provides a unique sanctuary for animal and plant species. While the immediate radioactive zone is closed to permanent residency, the site opened to tourists in 2011, meaning that people can now visit to see the effects of radiation on an environment firsthand. Other uses of the land include the recent construction of a solar power plant, a sign of hope for economic recovery and clean energy.
The most recent development at the Chernobyl plant by the time of this article has been the Russian invasion of Ukraine and subsequent takeover of the plant. This February, Russia took control of Chernobyl and its status, including radiation storage, is now unknown. Organizations like the International Atomic Energy Agency are on high alert, concerned that violent activity at a radioactive site risks a unique and unparalleled danger to the public.
Speculation over why Russian forces chose to occupy the plant include its strategic location as only 65 miles from Kyiv, the capital of Ukraine, and also to gain bargaining power from the potentially disastrous consequences of the nuclear waste contained at Chernobyl.
Overall, Chernobyl serves as a reminder of the devastating cost of humanity not fully understanding the magnitude of the technology we create, but also of our capacity to address these disasters and change from them.
