The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (officially Ukrainian SSR), which was under the direct jurisdiction of the central Moscow's authorities. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe. It is considered the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster).[1] The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy.

Following the Chernobyl nuclear disaster in 1986, various radioactive elements were released into the environment, including isotopes of iodine, cesium, strontium, and plutonium. These elements contaminated the surrounding area and spread across Europe, impacting the health of individuals and ecosystems. Efforts were made to contain and mitigate the spread of these radioactive elements in the aftermath of the disaster.
The Chernobyl disaster involved the release of radioactive materials, specifically radioactive isotopes of iodine, cesium, and strontium, which are byproducts of nuclear fission reactions.
The Chernobyl disaster in 1986 involved a nuclear reactor that used uranium-235 as its fuel. This radioactive fuel contributed to the catastrophic explosion and subsequent release of radioactive materials into the environment.
The Chernobyl nuclear disaster contaminated the water in the region with radioactive materials, such as cesium-137 and strontium-90. These radioactive elements entered rivers and groundwater, leading to long-term pollution and health concerns for those exposed to the contaminated water. Efforts have been made to monitor and clean up the affected water sources since the disaster.
It is estimated that Chernobyl will be radioactive for the next 20,000 years due to the long-lasting nature of some of the radioactive isotopes released during the accident. However, the most significant radiation should decrease substantially within the first few hundred years.

The explosion at the Chernobyl nuclear reactor released a variety of radioactive debris, including radioactive isotopes of iodine, cesium, strontium, and plutonium. These radioactive particles were carried by the wind and spread over a wide area, contaminating the surrounding environment.

Chernobyl is located in Ukraine. It is known for the Chernobyl disaster, which occurred in 1986 at the Chernobyl Nuclear Power Plant. The area around the plant is now part of the Chernobyl Exclusion Zone, which remains largely uninhabited due to radioactive contamination.
The Chernobyl disaster released radioactive materials equivalent to about 100 megaelectronvolts (MeV) of energy.
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.

Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
After disintegration all radioactive elements are transformed in other elements.
