There’s a lot of great invisible effects work in HBO’s Chernobyl, but one scene that I was astonished by, in particular, involved the ‘rooftop liquidators’, people sent up to clear radioactive debris from the Russian nuclear power plant’s rooftop in short bursts (it was bad news if they stayed any longer than 90 seconds each). It's a demand," he says.Jaan says the roof-cleaning scene depicted in HBO's mini-series Chernobyl mirrored real life events.He says he'll never forget those two minutes standing over the edge of an open nuclear reactor, shovelling radioactive graphite.Perhaps it was the adrenaline — perhaps the fear — that made him go blank.

"Jaan was shown on a small screen exactly which piece of debris he had to pick up with a shovel and throw off the roof of the reactor, but strictly warned against going too close to the edge.He had two minutes to complete the assignment — a bell would ring to tell him when to run back.The two-minute timeframe was to limit exposure to radiation, which could kill a man.But this wasn't communicated to the men at the time. But the truth is that the troops’ roof-clearing operation was made necessary only by bureaucratic infighting and arbitrary deadlines: a method to remove the debris using giant glue pads suspended from helicopters had been successfully tested on the roofs before Tarakanov’s men went in, but the government commission refused permission to deploy them.Tarakanov is a fascinating character — as a child, he watched his village burned to the ground by the Nazis, lied about his age to join the army, and subsequently wrote two of the Soviet armed forces’ textbooks on planned remediation in the aftermath of nuclear war.

Tarakanov insists to this day that he gave each man the option to leave if he did not wish to participate — but not one refused. "It had been briefly mentioned in one of the news bulletins in April. They were told they would be home soon, so most people left their pets behind with a little extra food and water. "When I got there, adrenaline was pumping so hard that I thought I'll turn the roof upside down. But all the officers said, 'Why are you fretting, the radiation levels aren't that high. Pets Although he was the deputy director of the Institute of Atomic Energy, he was not a reactor specialist, and indeed had to find an RBMK expert to brief him before he first got on the plane for Chernobyl on April 26. No one told them [about the risk of radiation].”Mr Ignatenko died from acute radiation sickness 14 days after being brought to hospital.Scientists and government officials were faced with the task of clearing the most radioactive materials from a roof close to the reactor, so they could entomb the dangerous area.They commissioned lunar and police robots to clean the nuclear waste as it was not safe for humans to go onto the roof.Chernobyl on HBO portrayed the attempt at clean up with the robots, and series creator Craig Mazin and podcast host Peter Sagal explained on accompanying podcast The Chernobyl Podcast how this happened.Mr Mazin explained on the podcast: “Exposure to radiation is cumulative, and it doesn’t go away.“That place would … kill you in a minute and a half.”The officials decided to to use Russian lunar landers, called Lunokhod, and a borrowed police robot.Joker was one of the latter robots, it was originally from West Germany, and was sent to the rooftop to remove the highly radioactive rubble.Two men risked their lives moving graphite to make sure Joker could move freely on the roof.However, the robot supposedly designed for these types of missions almost immediately shut down due to radiation exposure.Mr Mazin said: “The Soviets — and this is mind-blowing to me — they refused to tell anyone how bad the situation was.“Even then, months later, after the world knew about Chernobyl and knew what it meant they were still soft-pedalling just how bad it was to the point where they refused to tell the West Germans how much radiation was on that roof.“It was 600 percent or 700 percent more than it could handle.“And what blows my mind is the Soviet power system thought that was OK. Why not? When I explained that this wouldn’t be possible, he spent an hour swearing and haranguing me in Russian before dismissing me and my translator from the room. "Sometimes I think that maybe we didn't even want to talk about it or think about it," Jaan says.Then, a shimmer of hope emerged — in the unlikeliest of situations.A rumour had it that the very last leg of the assignment was going on the roof of the reactor to clean up as much debris as possible.Humans were going to be given a task that remote-control robots had previously attempted, but failed. Was the "Joker" robot fake? It happened. A medical officer went out onto the roof first, equipped with a version of the improvised protective equipment — a rubber apron lined with lead, and pieces of lead sheet tied around his neck, groin, head, and placed inside his boots — to assess the potential dose each man would receive, and calculations made accordingly. At first, it was believed that approximately 3,400 men did this job, but the real number came out at a later point. A nail-biting 90 seconds of invisible visual effects. In Pripyat, for instance, police patrols came across elderly men and women who had been forgotten about in the rush to evacuate, sitting alone in otherwise abandoned buildings days later, waiting for someone to tell them what had happened.I don’t believe anyone knows why Legasov committed suicide, nor do we know the extent of his understanding of the flaws in the RBMK design before the accident.
