Chernobyl - 25 Years After the Worst Nuclear Disaster in History


On April 26, 1986 the world’s worst nuclear catastrophe happened in the Ukraine. A nuclear reactor at the Chernobyl power plant exploded. The radiation that escaped in Chernobyl was four hundred times the amount that was released by the atomic bomb that was dropped over Hiroshima at the end of World War II. About 100,000 people had to leave their homes immediately after the explosion.

Neighboring villages had to be evacuated and up to today nobody has been allowed to live within 30 km of the plant. Pripyat , founded in 1970 to house the workers of the power plant , has become a ghost town. Before the disaster 50,000 people lived in modern apartment buildings. Today it is completely deserted with cars still parked on the streets. Radiation levels are still so high that nobody will be able to live here for the next one to two hundred years.


An area of about 150000 square kilometers was contaminated by radioactive cesium, which has a half life of 30 years. Most of the nuclear fallout came down on Bellarus, Russia and the Ukraine itself.

Even though Chernobyl does not produce electricity anymore about 4,000 workers still work at the nuclear power plant. They can only stay for two weeks at a time because of the high radiation.

25 years after the disaster the cleanup of Chernobyl is still going on. There is still almost 200 tons of radioactive material stored in the sarcophagus, which was built in only six months after the explosion in 1986. Today it is slowly breaking apart and cracks are letting radioactive material escape.

The Ukrainian government has promised to build a new shelter that will replace the old sarcophagus. This cover is expected to last for over a century but it is still not clear where the Ukrainians will get 800 million Euros to finance such a huge dome.

Debate is still continuing on how many people died in the Chernobyl disaster. 31 people were killed as a direct result of the accident. 30 more died of radiation sicknessdue to the blast. Thousands of cases of cancer have been detected in people who were children at that time.

The population in the area is still in danger. Greenpeace claims that thousands of Ukrainians are eating food that is contaminated by the nuclear blast although Ukrainian food ministry officials say that food is regularly checked. The environmental organization says milk, mushrooms and berries in the whole region will stay polluted for many decades to come.

Today, more and more tourists are coming to northern Ukraine. Tour guides in Pripyat show westerners the homes that they lived in before the explosion. Buses take them to the nuclear power station but stop a few hundred yards from the disaster site where they can spend 15 minutes on taking pictures.
