Nuclear 'time bomb' as radioactive Chernobyl fallout trapped in melting ice could be released all around the world

A HAZARDOUS “time bomb” of radioactive fallout from nuclear meltdowns and weapons testing is waiting to go off around the world.
Researchers have found evidence of nuclear fallout lurking in glaciers across the globe – frozen, but at risk of being released.

A team of international scientists studied nuclear fallout around the world.
They examined the presence of this radioactive material across ice-surface sediments in glaciers in the Arctic, Iceland, the Alps, the Caucasus mountains, British Columbia and Antarctica.
And it emerged that “man-made” radioactive material was lurking at all 17 sites surveyed.
Worse still, concentrations were found at least 10 times higher than levels elsewhere.

“They are some of the highest levels you see in the environment outside nuclear exclusion zones, said Caroline Clason, of the University of Plymouth, told the AFP.
Most nuclear fallout falls back down to earth as acid rain – which is typically absorbed into the ground.
But in chillier climes, radioactive material can fall as snow and settle in ice, where it forms a heavier sediment.
This collects in the glaciers and concentrates the levels of nuclear residue.
And major nuclear incidents – like the 1986 Chernobyl disaster – can spread radioactive material far across the world.
“Radioactive particles are very light, so when they are taken up into the atmosphere they can be transported a very long way,” Caroline explained.
“When it falls as rain, like after Chernobyl, it washes away and it’s sort of a one-off event.
“But as snow, it stays in the ice for decades, and as it melts in response to the climate, it’s then washed downstream.”

Clason’s team was also able to detect some fallout from Japan’s Fukushima nuclear meltdown in 2011.
However, researchers determined that it was still too early for much of the fallout to collect on ice from that disaster.
The study also discovered significant amounts of fallout from nuclear weapons testing.
“We’re talking about weapons testing from the 1950s and 1960s onwards, going right back in the development of the bomb,” Caroline said.
“If we take a sediment core, you can see a clear spike where Chernobyl was.
“But you can also see quite a defined spike in around 1963 when there was a period of quite heavy weapons testing.”
What is the Chernobyl disaster?Here’s what you need to know about the world’s worst nuclear accident

The Chernobyl nuclear power plant is situated near the now-abandoned town of Pripyat in Ukraine
The power plant exploded in April 1986 when its poorly designed fourth reactor suffered a huge power surge
The explosion and subsequent fires released a lot of nuclear radaition into the astmosphere
The intial explosion killed two people but radiation sickness quickly began to kill more plant workers and emergency services employees who were responding to the inicdent
Authorities were slow to release information about the extent of the disaster to the outside world until radiation alarms began to go off at a nuclear plant in Sweden
Trees surrounding the area absorded so much radition they died and turned red resulting in an area known as the ‘Red Forest’
116 000 people were evacuated from the surrounding area in 1986 and there is now a 30km exlcusion zone where it is illegal to live
Tourists who visit Ukraine can book a short tour of Chernobyl because a short time spent in the radiation is not thought to be harmful
The New Safe Confinement is the name of the shelter which now surrounds the exploded reactor and is intened to confine any radition that it stills gives off
This confinement was not compelted until 2018
Experts believe that the area won’t be safe for humans to live in for another 20,000 years

As global temperatures rise, there’s a growing risk that this nuclear fallout will be released back into the worlds.
This could potentially contaminate food and water supplies – although the study didn’t focus on the impact.
So it’s currently impossible to say to what degree human life is at risk from the melting radioactive glaciers.
What we do know is that radioactive materials lurking in the ice are highly dangerous.
One such material is Americium, a radioactive residue produced when Plutonium decays – and which can last 400 years.
“Americium is more soluble in the environment and it is a stronger alpha [radiation] emitter,” Caroline explained.
“Both of those things are bad in terms of uptake into the food chain.”
She added that Americium is “particularly dangerous”, and explained that these nuclear materials will be a marker of humanity’s impact on the planet for generations to come.
“These materials are a product of what we have put into the atmosphere,” the scientist warned.
“This is just showing that our nuclear legacy hasn’t disappeared yet, it’s still there.
“And it’s important to study that because ultimately it’s a mark of what we have left in the environment.”

An MIT historian recently claimed that Chernobyl may still be killing us.
Spraying chemicals into the sky is a perfectly safe way to stop global warming, according to one group of mad scientists.
Researchers recently proved that climate change is to blame for rising sea levels – as the risk of “megatsunamis” grows.
