The Fukushima disaster was the largest nuclear disaster since Chernobyl in Ukraine. It was the consequence of a 9.0 earthquake (the most powerful ever recorded in Japan) and a devastating tsunami, which killed almost 16,000 people.

The tsunami caused a meltdown at three of Fukushima's six reactors, and forced the evacuation of 100,000 people. 

Now, five years on, Getty photographer Christopher Furlong has taken a tour inside the Fukushima Daiichi power plant that is being decommissioned after the meltdown. He photographed the trained professionals that are working to decontaminate the area.

Take a look at some of his insightful images below.
