The largest nuclear accident occurred on the night of April 26, 1986, when the reactor of the fourth power unit exploded at the Chernobyl nuclear power plant. The explosion released radioactive materials into the atmosphere and caused a fire that lasted 10 days. The disaster resulted in thousands of deaths, as well as the evacuation of 350,000 residents from the cities of Chernobyl and Pripyat. After the initial liquidation of the consequences of the accident, the authorities continued to operate the remaining three power units, gradually shutting them down until the plant finally ceased work in 2000.
After the release of the Chernobyl series, tours to the site of the accident became especially popular. Travel companies conduct tours along the signed route in the "exclusion zone" of Chernobyl – the area around the plant. Radiation level in this area has been generally recognized as safe. He excursion includes a visit to all the main attractions, including the ruins of the village of Kopachi, which was demolished and buried after the disaster due to the high level of pollution, and the Red Forest – a pine massif destroyed by radioactive contamination.
