The eerie abandoned vehicles in Chernobyl's 'dead zone'

A huge armada of vehicles were used to clean-up the radioactive aftermath of the Chernobyl disaster 40 years ago. Many of them still lie rusting inside the exclusion zone.

In the early hours of Saturday 26 April 1986, a safety test at the Chernobyl Nuclear Power Plant in what is now Ukraine went horribly – almost apocalyptically – wrong.

Technicians cooling off one of the Soviet power plant's four reactors during a test to simulate an accidental loss of power were unaware of a crucial design flaw in the reactor. The power spiked, causing a thermal reaction when the cooling system was offline. Components inside reactor number four ruptured, causing steam explosions and a reactor meltdown, which destroyed the reactor building.

Radiation from the debris and the smoke from the reactor fire drifted across Ukraine, other states in the USSR, and eventually the furthest reaches of Northern Europe.

The explosions, and the resulting radioactive cloud, caused panic around the world. But the effects were most keenly felt in the area around Chernobyl, especially the "model city" that had been bult for its technicians, Pripyat.

This city of 49,000 people was surrounded by farmland and forest, dotted with villages and small towns. After initial paralysis – officials did not want to believe that a reactor in one of their model nuclear power plants could fail – an enormous evacuation plan rumbled into life.

In little more than 36 hours after the explosion, Pripyat's entire population was bussed out of the affected area, never to return to their homes. Another 68,000 were removed from other smaller settlements. And after the evacuation came the clean-up.

The full weight of the Soviet Union's civil defence network was brought in to deal with the disaster, the most serious nuclear event to have happened in peacetime. Countless trucks and buses were used to bring in the 500,000 military and civilian personnel who would have to deal with the zone's radioactive contamination, given the grisly designation "liquidators". A significant chunk of the Soviet Air Force's helicopter fleet was used to douse the reactor fire and cover other irradiated areas. Army scout cars and demolition vehicles – designed to work in the radioactive aftermath of nuclear explosions – were also brought in to monitor the "hot zones".

The work to clean up the toxic aftermath took many months. At the end of it, this enormous fleet of vehicles themselves become a poisonous problem with no quick fix.

The radiation made them too dangerous to return to service out of the zone, and so Soviet authorities set up vehicle graveyards for them, including the giant heavy-lift helicopters that had flown over reactor number four's fuming pyre. Two enormous sites were prepared in Rassokha and Buryakovka within the exclusion zone, and the vehicles were flown or driven there – and left to rust in the open air for at least 100 years until the radiation levels fell to normal levels.

When the zone around Chernobyl became one of Ukraine's unlikely tourist attractions in the late 1990s and early 2000s, the vehicle........
