Chernobyl is a city located in the current Republic of Ukraine (which was part of the then Union of Soviet Socialist Republics or USSR that existed until 1991) and whose name became world famous since the 26 night of April took place there a nuclear accident Registered as one of the worst in history.
That night of the 26 of April came the most terrible and compromising nuclear accident known to date. The scientific-technical expertise carried out during and after the event on the site of the nuclear disaster they allowed to know that everything began with a test that was carried out in the 4 reactor.
How did this catastrophic nuclear accident in Chernobyl occur?
According to data from Lars-Erik De GeerDe Geer and his team from the Swedish Defense Research Agency,
"... contrary to the assumption so far, it was a nuclear explosion and not a steam explosion."
The first triggered a second steam explosion. Until now it was supposed to have happened the other way around.
The aforementioned document De Geer and his collaborators refer ...
"... that in the core of the reactor, when the critical state was exceeded, a series of explosions occurred that projected radioactive material and debris through the shattered reactor building into the upper atmosphere."
Immediately, just three seconds after the detonation, the investigators assure that the explosion of vapor took place that finished destroying the cover of the reactor and sent other nuclear fission products and building debris to lower layers of the atmosphere. The air currents scattered all that waste.
What caused the worst nuclear disaster that has occurred in Russian territory?
The causes of the event are not yet fully understood, but what is certain is that the operation of the reactor went out of control of its operators and caused an explosion that expelled a large amount of radioactive material.
This material gave rise to a strong contamination in the space of the surrounding areas and in other European regions.
In such a way that after more than 30 years of that event, its analysis continues being the reason for a special scientific attention that seeks to discover with the greatest objectivity and possible certainty what was the real cause that originated it and how it can prevent something similar from happening .
What were the consequences of the appalling Chernobyl nuclear disaster?
The serious event that occurred in Soviet territory produced an uncontrolled escape from a radioactive cloud that for many days remained in the atmosphere of the area, of adjacent regions and of a large part of the territories of European countries.
Almost 350.000 people were removed from the most contaminated areas and resettled in other regions, 116.000 of them immediately after the incident. The experience was traumatic because it left many people unemployed and with serious physical and psychological consequences.
The surveys showed that those who did not leave or those who returned to their homes, could better cope with the subsequent period than those who were relocated. Tensions between the new and the former residents of the villages also contributed to the ostracism of the new arrivals.
Another important aspect is that the demographic structure of the affected areas was seriously impacted. Many skilled workers and entrepreneurs, mostly young, migrated, leaving a majority population of the elderly, almost all economically inactive to boost the recovery of the economy.
What results did the measures taken at Chernobyl show?
Despite the rapid intervention of the agencies created to deal with this nuclear catastrophe, the risk of deepening the lethal effects caused by the radioactive components that escaped their entrails forced the authorities to close the plant.
In addition, they had to build a sarcophagus around the damaged reactor that has even deteriorated, with the consequent danger of sinking and releasing radioactive dust that lies there. In this sense, the consequences have not ceased to be felt and still produce sequelae in its epicenter and in the entire broad scope of its context.
During and after what happened, thousands of people were then evacuated and it is estimated that 500.000 were exposed to the most terrible forms of contamination and death.
What was learned from this catastrophe in Russia?
After twenty years of this tremendous nuclear accident, an interesting report appeared that gathers the conclusions of the study on the effects of what happened in Chernobyl. This study was conducted by a team of over 100 experts and multidisciplinary training scientists under the responsibility of the United Nations Organization.
In that conclusive text of the 2005 it was ensured that in the future up to four thousand people could die of those who were exposed to the radiations during and after the nuclear disaster de Chernobyl.
Finally, the report urges to take the necessary measures to prevent catastrophes like these from happening again.
