When HBO’s Chernobyl hit screens back in 2019, one specific scene burned itself into the collective memory of the public. You know the one. A group of coal miners, led by a gritty, soot-covered foreman, strip down to nothing but their boots and caps to dig a tunnel under the melting Reactor 4. It was dramatic. It was shocking. But did the miners at Chernobyl mine naked in real life, or was that just a bit of Hollywood creative license designed to show how "tough" Soviet workers were?
The reality is actually a mix of extreme physical endurance and the kind of desperate improvisation that defined the 1986 disaster.

Basically, the answer is a "sorta." While they weren't exactly parading around completely nude in a synchronized line like the show suggested, the heat inside those tunnels was bordering on the suicidal. When you’re underground in the middle of a nuclear meltdown, "safety gear" becomes a relative term.
Why they were even down there
To understand the clothes—or lack thereof—you have to understand the mission. By May 1986, the liquidators realized they had a massive problem. The molten core, a lava-like substance called corium, was burning through the concrete floor of the reactor. Below that floor were huge pools of water. If that white-hot corium hit the water, it would trigger a massive steam explosion that some scientists feared could wipe out most of Europe.
They needed a cooling system. Fast.
The plan was to dig a 150-meter tunnel from Reactor 3 over to Reactor 4 and install a liquid nitrogen heat exchanger. They called in coal miners from Tula and the Donbas region. These guys were used to tough conditions, but Chernobyl was a different beast entirely.
The heat was unbearable
The temperature inside those hand-dug tunnels was roughly 50°C (122°F). Try to imagine working in a sauna while swinging a pickaxe. Now add the fact that there was zero ventilation because they couldn't risk pulling in contaminated air from the surface.
It was a pressure cooker.
Vladimir Naumov, one of the miners who worked on the site, has been interviewed many times about those weeks. He didn't claim everyone was naked, but he did admit that the heat was so intense that many of them stripped down to their underwear. The sweat was constant. Some accounts suggest that because the white protective suits provided by the government were essentially plastic bags that trapped heat, the miners simply tore them off. If you’ve ever worn a cheap raincoat while running, you know the feeling. Now imagine doing that in 120-degree heat next to a melting nuclear core.
Fact vs. Fiction: The HBO Version
The show’s creator, Craig Mazin, actually addressed this on the Chernobyl podcast. He admitted that while the show depicted them as fully nude to emphasize their vulnerability and defiance, the historical accounts he relied on (like Svetlana Alexievich’s Voices from Chernobyl) varied.
Some miners said they took everything off. Others said they kept their boots and a thin layer of cloth on.
One miner, Boris Baranov, famously noted that the "nakedness" was a bit exaggerated for TV, but the sentiment was spot on. They were working in a hole in the ground with no fans, no breeze, and a ticking clock. If you’ve ever done manual labor in a humid basement, you’ll get why a heavy lead apron or a thick cotton jumpsuit was the last thing you'd want to wear.
Radiation and the "Naked" Risk
Here’s the thing that sounds crazy to us now: the miners felt that being naked was actually safer in a weird, distorted way.
The logic? If your clothes get soaked in radioactive dust and sweat, they hold that radiation against your skin all day. By working without clothes and then scrubbing down immediately afterward, some believed they were actually reducing their prolonged exposure. It’s scientifically questionable since Alpha and Beta particles can still do damage to bare skin, but when you're 20 years old and told you're saving the world, you don't always check the physics.
Besides, the radiation levels inside the tunnel itself were actually lower than on the surface. The earth above them acted as a shield against the gamma rays coming from the reactor. The real danger was inhaling the dust. They were supposed to wear respirators, but honestly, have you ever tried to breathe through a thick filter while doing heavy cardio in 50-degree heat? Most of them pulled the masks down.
What happened to the Tula miners?
There’s a common myth that these guys all died within weeks. That’s not true. While many suffered long-term health issues—cardiovascular disease and various cancers—a surprising number of the "naked miners" lived well into their 60s and 70s.
They were young. They were fit. They were the elite of the Soviet labor force.
Still, the sacrifice was immense. They dug that tunnel in 45 days. It usually would have taken months. And the kicker? The heat exchanger they installed was never even turned on because the corium eventually cooled down on its own before reaching the water. They did all that work, took all those "naked" risks, for a safety net that wasn't even needed in the end.
How to learn more about the real Liquidators
If you want to move past the dramatization and see the real faces of the people who saved the continent, look for the photography of Igor Kostin. He was one of the few photographers who stayed on-site for months. His photos show the grit, the makeshift lead vests, and the sheer exhaustion of the workers.
You can also read Voices from Chernobyl by Svetlana Alexievich. It’s a tough read, but it’s the closest you’ll ever get to the actual voices of the miners, soldiers, and wives who lived through the fallout. It's not a dry history book; it's a collection of raw human experiences.
Actionable steps for history buffs:
- Check the primary sources: Look for interviews with Vladimir Naumov. He’s one of the most vocal surviving miners who gives a grounded perspective on what happened underground.
- Understand the science of shielding: Research how "earth shielding" works. It explains why the miners were able to survive the tunnel work while the "Bio-robots" on the roof of the reactor were receiving lethal doses in seconds.
- Visit the Chernobyl Museum in Kyiv: If you ever find yourself in Ukraine, the museum has an incredible collection of personal artifacts from the liquidators, including the actual clothing (and what’s left of it) used during the cleanup.
The image of the naked miner is a powerful symbol of the human spirit vs. the machine. Whether they were fully nude or just stripped to the waist, the reality remains: they went into a hole in the earth to stop a catastrophe, armed with little more than shovels and sheer guts.
