The Chernobyl disaster was a well-known nuclear accident of catastrophic proportions that occurred on 26 April 1986, at the Chernobyl Nuclear Power Plant in Ukraine (then in the Ukrainian SovietSocialist Republic, part of the Soviet Union). It is considered the worst nuclear power plant accident in history and is the only level 7 event on the International Nuclear Event Scale.
LiquidatorsThey were firefighters, workers, soldiers and volunteers who were responsible for extinguishing fires and build the sarcophagus, a structure designed to contain the radiation released during theaccident. These people risked building without protective gear and a large amount of radiation absorbed. This great service to humanity proved fatal to thousands, and left grave consequences in many others.Almost everyone suffered side effects and some died, although figures are not known with accuracy. During the pre-construction work of this structure was detected, in what remained of the roof of theplant, had scattered remnants of the graphite rods and nuclear fuel debris, thrown there by the colossal proportions of the explosion that destroyed everything the building. These materials had to bethrown from one roof, within which at the time was the reactor core.
For this task, at first, try to use mechanical means such as remote-controlled robots, but the amount of radiation was such thatthese robots, soon after operation in these conditions, ended up damaged because their circuits were affected and damaged by exposure. Consequently, the work must be done by human operators. Theseoperators, called biorobots, worked for a week throwing those wastes from what remained of the roof.
In periods of maximum two minutes (when 45 seconds, and posed a lethal dose of radiation) over 3000people, mostly soldiers, carried the deadly task. The Soviet government offered to swap the two years of compulsory military service for two minutes in the reactor working. Many soldiers agreed....
