The abandoned city of Pripyat lies still and silent under the deadly radioactive dust of the Cheobyl nuclear disaster.
Reality 51
When Wojciech Pazdur was 8 or 9 years old, his father, a Polish nuclear physician, came home from work and said all their equipment had gone crazy. He said that meant "something bad had happened".
It was 26 April 1986 in what was then the Ukrainian Soviet Socialist Republic of the Soviet Union, and something very bad had happened. The Cheobyl Nuclear Power Plant had exploded, sending radioactive debris into the sky over Europe as emergency crews battled deadly radioactivity to bring the catastrophe under control.
Thirty years later, Wojciech Pazdur is part of the team that visited the abandoned city of Pripyat, home of the Cheobyl plant, to create a 3D virtual reality version of the now-deserted area. To mark the 30th anniversary of the disaster, which killed 31 people and contributed to the long-term health problems and deaths of thousands more, the team has released a haunting 360-degree video that allows you to explore the eerie remains of a city that was once home to nearly 50,000 people.
Pazdur is creative director at Reality 51, a Polish video game development company. The 3D version of Cheobyl and Pripyat is produced using photogrammetry, a technique that involves laser scanning and photographing the area in precise detail. This video explains how it's done:

The project began as the team set out to take viewers to an interesting place they could never visit in real life. "At first it was play -- how fun it would be to go to Cheobyl?" Pazdur told CNET's Ian Sherr. "But then we went to Ukraine and talked to people...I started to understand this is serious. It's important to bring the world's attention to the disaster."
Up to 60 percent of the proceeds from the project, which launches in June, will go to charities supporting victims of the disaster.
Among the people most affected were the "liquidators" who worked to contain the disaster, including firefighters, medical personnel, soldiers and local people. Radioactive levels were so high that liquidators clearing the rooftops of surrounding buildings could only work for 40 seconds at a time.

"They didn't have proper protective suits," said Pazdur. "We heard from one man they had better suits but didn't wear them to avoid scaring the other workers." Liquidators were exposed to horrific levels of radiation, many without knowing how dangerous the situation was.
In the immediate aftermath of the explosion, 237 people showed signs of acute radiation sickness. Within 3 months, 31 were dead. In the 30 years since, the disaster has contributed to serious illness and birth defects for people in large parts of Ukraine, Belarus and Russia.
The city of Pripyat was evacuated the following day, and today it stands empty, abandoned and ruined. Even now, the silent city is a dangerous one. "You have to be all day on your feet -- if you sit you may get [radioactive] dust on you," Pazdur said of the precautions his team had to take when photographing and scanning the area. "You have to watch out because you can't walk into the bushes. You cannot touch anything. You cannot eat. You can drink but you have to spit first.
"When you are in Cheobyl you feel different because there are no sounds around you," said Pazdur. "There are no birds, and no insects.
"There are a bunch of snakes," he added.
The VR documentary will be available for the Oculus Rift headset at first, then later for the PlayStation VR and HTC Vive. This latest generation of virtual reality is available for you to take home and try out, but Pazdur notes that virtual reality is still so new that there a lot of questions. "How do you tell stories in VR?" he asked. And VR is far from a proven commercial prospect. "No one knows how to ea money in VR," said Pazdur. "But even if we won't ea a whole lot of money, at least we can make something meaningful."
