So could you survive a nuclear bomb in a fridge?
You would be better off getting as far away from the blast as possible. But if you were in a fallout shelter or bunker and the bomb did go off, your chances of survival are much higher.
If you were very close to ground zero when the bomb went off, you will likely die regardless of whether or not you were in a fridge. This is why an underground shelter or bunker is so important. That being said, if you were further away from the scene of impact and in a fridge at the time (but still within range), then there is a good chance that it would shield some of the radiation.
What happened on the day of the atomic bomb?
Most people know that the atomic bomb was dropped on Hiroshima, but they don’t know how it happened.
On the 6th of August in 1945, an American B-29 bomber dropped a single atomic bomb over the city of Hiroshima. The bomb killed so many people instantly and left tens of thousands injured or maimed by burns or radiation poisoning. The bomb was detonated a few hundred feet above ground level and demonstrated the cruelty that these kinds of bombs represent from then on.
The blast was so powerful that it could be seen tens of miles away in some parts of Japan. It ushered in a new era of the realities of what an atomic bomb can do.

How could your fridge work?
So, why would a fridge work? The answer is it would not work, not like what you see in movies such as Indiana Jones.
These are the ways that you could survive an atomic bomb or nuclear bomb in a fridge. It would be a result of the door being closed first off. Then if it is airtight as well as lead-lined. It also would need to be far enough away from the blast or it would not work. The fridge would need to be underground(bunker) or in a fall-out shelter of some kind. So if it was far enough away and in a bunker type of shelter then yes. On its own probably not. The further away from the blast the better your odds.
Can you survive a nuke in a lead-lined fridge?
In a lead-lined fridge, you would not be safe.
The truth is that lead-lined refrigerators will not protect you from the blast of a nuclear bomb, which is the biggest problem when you’re talking about surviving a nuke. The explosion will destroy everything around it (including your lead-lined fridge), so even if you were to survive the initial blast, there would be nothing left to shield you from radiation.
How Far Underground would you need to go?
How Deep Underground To Survive A Nuclear Blast?
The way that you would survive a nuke in a lined fridge would be in an underground shelter that was made out of concrete. There would need to be an air filtration device capable of filtering out radiation. If you ever found yourself in a shelter of this kind(bunker) and a nuke is about to hit and you decide to go into a fridge.
Your chances of survival are higher, but a fridge on its own is not going to work. If you are in an underground shelter the chances of going into a fridge would be a little overkill in my opinion.

You can’t survive an atomic blast, but it’s unlikely that you could survive one in a fridge.
Distance from the detonation site is essential, the further the way the better. So if you were far enough away from the blast, like in a bunker or shelter, then you would survive a nuclear bomb. The fridge “could” protect you from the radiation, but it wouldn’t protect your body from being thrown against things and breaking bones. It really would not protect you from radiation for a long-term situation of more than a minute.
Then think of your need to get oxygen which you would not be able to do without opening up the fridge. If you were closer to the detonation site, your fridge could burn up or break apart with you in it. The chances of getting hit or killed by debris would be significant too.
You could even get killed by falling debris. If you were in a bunker with thick walls and an underground ceiling, then chances are that the only thing that could happen to you is momentary deafness. It is less likely because sound travels through the air far better than through solid objects like dirt or concrete walls.
If an underground shelter is not on the cards for whatever reason that may be then your best bet is to head for somewhere that has thick walls and pray to whoever you believe in. If you live in the city, subways(train tunnels) could be a good option if you find yourself in a pinch.
So, could you survive a nuclear bomb in a fridge?
The answer is most likely no, but it doesn’t hurt to be prepared just in case. Have you taken steps to prepare for a potential nuclear attack? An underground shelter/bunker would be the best way to survive a nuclear bomb.
