When did Chernobyl happened?

The Chernobyl Nuclear Power Plant in Ukraine erupted in the early morning hours of April 26, 1986. It was one of the world's worst nuclear accidents in human history. Even after many years of scientific inquiry and government investigation, many issues concerning the Chernobyl disaster remain unresolved. Here we talk in detail about Chernobyl and when did Chernobyl happened?

When did Chernobyl happened?
On April 25 and 26, 1986, at the Chernobyl nuclear power plant in the Soviet Union, now in Ukraine, the Chernobyl tragedy occurred. It is known as one of the scariest nuclear power plant tragedies in history.
When employees of nuclear reactor Unit 4 performed a poorly prepared experiment, the Chernobyl accident happened. On April 26, 1986, during a low-power test, the Number Four RBMK reactor at the Chernobyl nuclear power facility in Ukraine went out of control, resulting in an explosion and fire that destroyed the reactor building and sent massive amounts of radioactive materials and emission into the atmosphere.

The reactor's power-regulating system and emergency safety systems were off, and control rods were removed from the core, enabling the reactor to run at 7 percent power. The reactor's uranium fuel overheated and melted through the protective barriers. RBMK reactors lack an isolation structure. As a result, radioactive materials such as plutonium, iodine, strontium, and cesium were widely dispersed. Furthermore, as air reached the RBMK reactor core, the graphite blocks employed as a moderating material caught fire, contributing to the release of radioactive elements into the environment. These errors ended in an uncontrollable chain reaction resulting into multiple explosions.

Some reports claim that two persons died in the Chernobyl disaster's early explosions, while others claim that the number was closer to 50.  After the explosion, twenty-eight firefighters and emergency clean-up personnel died of Acute Radiation Sickness, and one died of heart arrest. Hundreds more people were exposed to dangerous radiation and many of them died. In addition, tens of thousands of people were predicted to die from radiation-related diseases, including cancer.

Chernobyl's nuclear tragedy resulted in widespread radiation illness and pollution. Radionuclides in the range of 50 to 185 million curies leaked into the atmosphere. Hundreds of thousands of acres of forest and farmland became poisoned, livestock was born with abnormalities, and humans experienced long-term health consequences. At least 1800 documented cases of thyroid cancer in children aged 0 to 14 years old at the time of the accident have been documented, which is far higher than the general ratio. The psychological effects of Chernobyl were and continue to be pervasive and significant, resulting in suicides, and drinking problems, among other consequences.
Chernobyl disaster left a long-lasting impact on both the living organisms and the surrounding environment. People are still experiencing its effects in different forms. They are still in danger, exposed to the elements, and battling from the front lines.
