24 years to the day since it exploded, reactor Number Four at Chernobyl in Ukraine is still leaking radiation.
Time, rain and stagnant water have weathered the concrete shield covering the site of the nuclear blast.
Only security officials are allowed to enter the 30 kilometre exclusion zone around Chernobyl.
Above 30 on the monitor indicates a dangerous level of radiation and here it is already showing 165.
The Chernobyl nuclear disaster took place in the early hours of April the 26th, 1986, when the reactor exploded, contaminating the then Soviet states of Ukraine, Russia and Belarus.
The fallout also spread to many parts of Europe.
The UN has put the death toll from contamination at around 4000, but this is disputed by NGO’s involved at the site.
The new steel skin will cover the reactor and is being built by two french companies. At 18,000 tonnes, it will be two and a half times as heavy as the Eiffel Tower.
The Chernobyl anniversary coincides with a swathe of anti-nuclear demonstrations across Europe.
In Hamburg, more than one hundred thousand people joined hands to form a human chain, to protest against the use of nuclear energy.
