The Chernobyl disaster remains one of the two level 7 incident on the international Nuclear Event Scale (INES) making it the biggest man-made disaster of all time.
Radioactive isotopes, such as caesium-137, iodine-131 and strontium-90, were released into the air.
Belarus received 70% of the fallout from Chernobyl, which contaminated one fifth of the country’s land used for agriculture.
In the case of Chernobyl, 31 people died as a direct result of the accident; two died from blast effects and a further 29 firemen died as a result of acute radiation exposure (where acute refers to infrequent exposure over a short period of time) in the days which followed.
The Chernobyl Forum, a group of eight U.N. agencies, and the governments of Ukraine, Belarus and Russia, have estimated the death toll at only a few thousand as a result of the explosion. U.N. agencies have said some 4,000 people will die in total because of radiation exposure.
800,000 men risked their lives by exposing themselves to radiation in order to contain the situation. 25,000 of these have died and 70,000 are disabled.
20% of those deaths were suicides
The environmental group Greenpeace places the eventual death toll at 93,000 cancer deaths world wide.
Greenpeace expects up to 60,000 cases of thyroid cancer from the incident
Around 97% of the radioactive material remains in a crumbling sarcophagus
A make-shift cover — the ‘Sarcophagus’ — was built in six months after the explosion. It covers the stricken reactor to protect the environment from radiation for at least 30 years.
The sarcophagus locked in 200 tons of radioactive corium, 30 tons of highly contaminated dust and 16 tons of uranium and plutonium
In 1992, Ukraine’s government held an international competition for proposals to replace the sarcophagus
On 17 September 2007 Vinci Construction Grands Projets and Bouygues Travaux Publics announced that they won the contract to build the New Safe Confinement as 50/50 partners of a French consortium named Novarka
The New Safe Confinement (NSC or New Shelter) is a structure built to contain the remains of the No. 4 reactor unit at the Chernobyl Nuclear Power Plant near Pripyat, Ukraine, destroyed during the Chernobyl disaster in 1986. The structure also encloses the temporary “sarcophagus” built around the reactor immediately after the disaster.
The NSC was designed with the primary goal of constructing a sarcophagus capable of containing the radioactive remains of Reactor 4 for the next 100 years. It also aims to allow for a future partial demolition of the original sarcophagus, which was hastily constructed by Chernobyl liquidators after a “beyond design-basis accident” destroyed the reactor on April 26, 1986.
According to a project official, construction completion will be delayed until May 2018 due to a contractor being unable to finish its works in time.32 The reason is the extremely high level of radiation, forcing workers to limit their presence at the site to a minimum.
A 30-km (19-mile) exclusion zone is in place round the disaster site.
The radiation leak caused the nearby forest to turn a bright ginger color, thus the forest was named the “Red Forest”
Wildlife has made a comeback in this area and there are said to be more than 60 different types of mammals living there including wild boar and elk.
The region has become one of the world’s most unique wildlife sanctuaries with thriving populations of wolves, deer, beavers, eagles, and other animals.
200 tons of radioactive materials are still inside the reactor
Chernobyl’s last reactor was shut down in 2000
Chernobyl engineers shut down the last functioning reactor, Number Three, in December 2000. Radioactive nuclear fuel is still being removed from the plant.
Officials say that it could take up to 100 years before the station is completely decommissioned.
