It is still the world’s worst man-made disaster.
The families of those killed in the 1986 Chernobyl nuclear disaster have gathered in Moscow to remember, and pay their respects.
Thousands of workers – mostly Ukrainians, Russians and Belarussians – worked to get the accident under control.
Many died as a result of contamination during their efforts to make the site safe and secure.
The reactor exploded in the early hours of April the 26th, 1986, contaminating the then-Soviet states of Ukraine, Russia and Belarus.
24 years to the day since the blast, reactor Number Four is still leaking radiation.
Time, rain and stagnant water have weathered the concrete shield covering the site of the blast.
Two french companies are collaborating to build a replacement steel skin for the reactor. At 18,000 tonnes, it will be two and a half times as heavy as the Eiffel Tower.
Two kilometres from Chernobyl, Pripyat was a model city, built to house the plant’s workers and their families.
These days, it is a eerie ghost town. The inhabitants were evacuated in a rush, leaving even their most personal belongings behind.
