  • Just over 33 years ago in

  • 1986 the worst nuclear accident in history took place at a nuclear power plant here in Chernobyl

  • Located only about 60 miles north of Kiev a city of almost 3 million people during a late-night

  • safety test a

  • Combination of critical reactor design flaws and human error built up to cause a massive steam

  • explosion in nuclear reactor four of the power plant which caused an open-air graphite fire over

  • 400 times the amount of radiation

  • Released by the Hiroshima bomb was unleashed into the atmosphere by the accident and a radioactive cloud spread over the entire

  • European continent

  • Contaminating places as far away as the United Kingdom but the vast majority of the radiation

  • Affected the communities immediately surrounding the power plant at Chernobyl

  • the radiation was so intense in certain parts of the reactor building following the explosion that an

  • Unprotected worker could receive a fatal dose in less than a minute over the coming days and weeks

  • 134 servicemen who responded to the fire heroic alia were hospitalized for acute radiation syndrome or

  • ARS of whom 28 firemen and operators died within months

  • The Soviet army then began establishing the Chernobyl exclusion zone

  • Forbidding any civilians from entering within a 30 kilometer radius around the exposed reactor

  • That was the most severely contaminated

  • area and evacuating everybody inside this zone still exists in Ukraine today and is roughly the same size as

  • Luxembourg, it was once home to

  • 120,000 people across cities like Pripyat and Chernobyl, but it's been almost entirely uninhabited now for over 30 years

  • today exactly

  • 197 people still choose to live inside of the exclusion zone for whatever

  • Reason, but it's not as dangerous today as it used to be the radiation levels are significantly less than what they could have been

  • Thanks to the efforts of the Chernobyl Liquidators back in

  • 1986 the Soviet government called up on

  • 600,000 people to come in and work cleaning the zone up after the disaster

  • It was no stretch to say that the reactor for building was the most dangerous place to be at in the entire world in

  • 1986 but that didn't stop the liquidators from constructing the

  • Sarcophagus a giant concrete and steel tomb to lock away the most dangerous place in the world forever

  • the sarcophagus entombed over 200 tons of highly radioactive

  • Corium lava 30 tons of highly contaminated dust and 16 tons of exposed uranium and plutonium

  • By the time that the core was sealed away inside over

  • 26 days worth of additional natural background radiation had already been unleashed onto the planet

  • There was only one problem though. The sarcophagus wasn't designed to last forever. It was only designed to last for 30 years until

  • 2016 the liquidators had constructed the

  • Sarcophagus and as quickly a time as possible in order to minimize their own exposure and the world's exposure to the radioactive

  • Poison inside and as a result, the building was pretty shoddy and this is partially why Chernobyl still poses a massive problem today

  • repairing the sarcophagus from the inside is considered to be impossible because the radiation levels inside are still estimated to be as high as

  • 10,000 roentgens per hour

  • That is enough to kill you

  • If you step inside for just three minutes and enough to fry any robots the deterioration of the sarcophagus over the years since its construction

  • Threatened to release all of this poison back out into the world

  • but that wasn't the only danger on the inside of the sarcophagus rests the upper biological shield or

  • Ubs a concrete slab that was thrown upwards by the reactor explosion and now rests at a 15 degree angle

  • Inside of the tomb it's only supported by debris, which means that it could likely collapse at some point

  • Exacerbating the dust problem inside and possibly damaging the sarcophagus itself further which could result in radioactive dust

  • Leaking onto the outside

  • something had to be done before the sarcophagus fell apart and everybody knew it and so

  • Work began on a new structure that would cover the entire

  • sarcophagus inside of it which covered the entire

  • Reactor building inside of it sort of like the deadliest and least pleasant nesting doll to ever exist

  • The new structure became known as the new safe confinement

  • building and unlike the sarcophagus

  • It was designed to entombed everything inside and last for the next century until at least

  • 2117 it took 1200 workers seven years and

  • 2.15 billion euros to finish constructing equal to about 2% of Ukraine's entire GDP in

  • 2017 if the United States spent 2 percent of their GDP on a single project it would cost about

  • 388 billion dollars as the biggest movable structure ever built the new safe confinement was finished in 2016 and slowly

  • Rolled into place over the old unstable sarcophagus and reactor building over a period of two weeks

  • hopefully trapping the nightmare inside forever about

  • 3,000 people currently work inside and around the building today as they work to dismantle the unstable

  • Sarcophagus and eventually remove the tons of dangerous radioactive material inside of it for a safe burial somewhere else

  • There is no time estimate for how long this process is going to take

  • But it likely will last for at least a decade or more

  • It's still potentially highly dangerous and workers are required to carry dosimeter x' to keep track of their radiation exposure at all times

  • if a workers

  • Annual limit is ever reached their site access is canceled and they're banned from returning the annual limit can be reached by spending just 12

  • minutes above the roof of the 1986 sarcophagus or a few hours around its chimney the exclusion zone gives off a

  • Feeling that the disaster was contained to that area

  • But that's not really true dangerous levels of radiation were dumped all across Belarus

  • Ukraine and parts of Russia and not to everybody who died as a result did so immediately

  • many victims and liquidators came down with dangerous cancers later on in their lives and the UN estimates that at least

  • 4,000 people have actually died from cancer directly related to the accident other studies claim that the number is actually somewhere closer to

  • 93 thousand cancer related deaths some health officials estimate that over the next 70 years. There will be a

  • 28% increase in cancer rates across the heavily exposed areas of Belarus, Ukraine and Russia

  • So the nightmare is far from over the Ukrainian government alone is currently paying out survivors benefits over

  • 35,000 families and the economic impact in Belarus alone where most of the radiation landed has been estimated to sit at

  • 301 billion dollars more than five times the annual

  • GDP of Belarus the total cost of the disaster has been estimated to be at least

  • 350 five billion dollars, but that was back in 2009

  • so that doesn't factor in any additional costs in the decades since

  • Considering for a moment that the 2011 Japan earthquake and tsunami and subsequent nuclear

  • Disaster at Fukushima is the most expensive disaster that's been properly calculated at a staggering

  • 411 billion dollars. It's likely that if the ongoing costs of Chernobyl were properly calculated up to today

  • It would probably steal that number1 spots. Despite a weird tourism

  • Boom to the area around the disaster in recent years the long lasting effects of cancer in the ongoing

  • Confinement and demolition work at the reactor itself

  • Means that Chernobyl is still a global problem in it isn't over yet

  • it will still be anywhere between 20 and several hundred years depending on the source you take until the area around Chernobyl is

  • Completely safe to live around a permanent again

  • If you came to watch this video after watching the Chernobyl miniseries on HBO, you were probably not alone

  • I was specifically inspired after watching the series myself to create this video and do more research into what's going on there now

  • One of the most common questions that I get asked all of the time though is how I got started making videos like this on

  • YouTube I'm sure many of you watching this right now want to make a video about something that you're passionate about

  • But you may be where I was about three years ago and not really know where to begin learning how to do all of that

  • Thankfully though this is one of tens of thousands of skills that

  • Skillshare can teach you their animation for illustration course is taught by Abby lossing a

  • Former staff illustrator from BuzzFeed and vice news that will teach you how to make animations using Photoshop and After Effects which are the exact
