How Deep Underground To Survive A Nuclear Blast?

When it comes to nuclear blasts, there are a lot of things that go through people’s minds. One of the most common questions is “how deep underground do I need to be to survive?” The answer to that question depends on a few factors, including the radius of the blast and the type of bomb.





When a nuclear blasts happens it is unbelievably powerful and destructive. You do not want to find yourself caught outside when one occurs. So if you do, without any shelter, your chances of survival are nearly zero. The only thing you can do is drive as far as you can in the opposite direction. That’s why it’s so important to seek shelter as soon as possible after a nuclear blast occurs. Without shelter, you’ll be exposed to deadly radiation and the long list of horrible affects.




The wind is another factor that has to be taken into account. This is because of the speed at which the wind will be traveling. It will be filled with all types of debris which could easily kill you. Think of all the debris within the wind, its truly frightening to think about!


Not to mention that the air may be filled with various types of debris, which can cause injuries if inhaled. So finding shelter is the most important thing you can do to improve your chances of surviving a nuclear blast. Once you’re in a shelter, stay there until it’s safe to come out. Don’t try to go outside until the all-clear has been given by authorities. Remember, your best chance of survival is to find shelter and stay there until the danger has passed.

Do Not Go Out


In the event of a nuclear blast, it is vital that you find shelter and stay inside for at least two weeks. The effects of the blast will lessen each day, so there is no rush to leave your shelter. Going outside before the effects have dissipated completely can be incredibly dangerous, so it is best to wait until it is safe. Going out no matter what may seem tempting, but the risks are simply not worth it. No matter what, do not go outside until you are absolutely sure it is safe to do so. Doing just this alone increases your chances of survival incredibly.

Why is it so important to be underground?

The reality is that a nuclear blast is a powerful and deadly explosion. This explosion carries with it unnatural amounts of light and heat, as well as catastrophic pressure wave, and widespread radiation. This is why being underground is key, for when a nuclear blast occurs, you could suffer serious injuries or even death. Even if you are a few miles away from the blast, you need to take shelter in an underground shelter to protect yourself from the radiation. Radiation exposure can cause radiation sickness, which can lead to death. That is why it is so important to be underground when a nuclear blast occurs.

The benefits of having an underground shelter can not be ignored because it shields you from the blast wave, debris, and radiation. If you have time to take shelter before the blast wave arrives, get underground as quickly as possible. The more dirt and shielding material between you and the radiation, the better.

How deep underground in order to survive a nuclear blast?

Well it will depend on a few different factors. The first would be if you sustain a direct hit. The chances are extremely unlikely that your bunker would take a direct nuclear blast. What will occur is the impact on the surrounding area. This is where you would fall under.

So how far underground should you go to survive a nuclear blast? It would be 10 feet as this is a sufficient amount of earth that will protect you. It is not to much, but a good rule of thumb when determining depth of a underground bunker.

What if you can not go underground?

Then it is time to hunker down in your home. The best thing that you can do is not go outside for any reason. This will increase your chances of survival.

If you have more than one level in your home then I would recommend not being on the ground floor. The possibilities if you have a home with more than one floor would be a basement or in the middle of your home. You want to put yourself the furthest away from the outside world, as radiation will be everywhere.

What should I do if i have been exposed to radiation?

Well if you find yourself, having been exposed after a nuclear blast you should do the following things.

If you have been exposed to radiation, it is important to take quick and decisive action in order to minimise the risk of harm. The first step is to remove any radioactive materials from your person, so be sure to take off your clothes and place them in a sealed bag. It is also crucial that you shower as soon as possible, using soap and water to remove any contaminants from your skin. Blow your nose ten times in order to clear any harmful particles from your nostrils. When doing these simple steps, you can help to ensure that you do not suffer any long-term effects from exposure to radiation.

How Far Will The Impacts Reach


This will be dealing with the radius of the nuclear blast and how far it will reach. If you know or attain information that this was a large nuclear blast then you will need to be further away or hunker down a little longer. It will increase how many miles the damage will go to depending on the size of the nuclear bomb. So make sure to have a radio, so that you can receive important information about whats going on outside.


The Materials You Need To Build A Fallout Shelter


Most people don’t realize how important it is to have a nuclear blast shelter in their home. With the current state of the world, it is more important than ever to be prepared for anything. A nuclear blast shelter will protect you and your family from the deadly radiation that accompanies a nuclear explosion.


There are many materials that can be used to build a nuclear blast shelter, but concrete is by far the most effective. Concrete is extremely strong and durable, and it can withstand the immense pressure of a nuclear explosion. Rebars should be used to reinforce the walls of a concrete bunker, making it even more resistant to collapse.


In addition to being strong and durable, concrete is also very inexpensive in comparison to other building materials. This makes it an ideal material for building a nuclear blast shelter on a budget. With a little bit of planning and some elbow grease, you can build an incredibly sturdy and affordable nuclear blast shelter using concrete and rebar.


I personally have helped a good friend of mine build his own bunker from scratch. This is what we did to building an underground bunker. It was not difficult by any means and we used the following things:


  • Cinder blocks
  • Concrete Mixer
  • Gravel
  • Cement
  • Excavator

Those were the only things that we used to build the shelter. We did not hire this out, and put in some sweat equity. We used the excavator to dig out a large enough hole that was a square in shape. Then we poured the foundation one wheel barrow at a time. Is it easier to hire a truck to pour concrete for you? Yes. We wanted to make sure that this truly would only be known by family and close friends. We finished with the foundation which was a simple slab foundation we let it dry.


Once it dried we started laying out our cinder blocks and made sure everything was level. We then started to build the walls. The walls were two cinder blocks in width. We could have just a one cinder block in width wall but we wanted the extra peace of mind and strength.


This took as longer than expected because of the thickness of the walls. There was rebar that was put down each of the cinder blocks. Once that was accomplished we then bought another concrete mixer. We got a few hands on board and filled the cinder blocks with concrete throughout.


The roof of the structure was done by building a form with plywood. It did not go on top of the cinder blocks but was on the inner side of the walls. Then we put together wooden railing to create a mold.


After all of that we bought three jack posts to strengthen our form. Once all that was accomplished we put in rebar within the form where the concrete would go. Then we filled the form with concrete. This then created a strong concrete roof.


Through out the build, we made sure to drill holes and PVC piping to make sure airflow can come in.  The most important thing beyond anything else would, getting an air filtration unit for the bunker.  In the future my friend plans on putting in a septic tank next to it and plumbing for a more long term bunker situation. We installed a steel door to finish it off.


One great benefit of building a shelter/bunker like this would be how cold it is. It is always a very comfortable temperature inside in comparison to the outside.


How deep does a nuclear blast go?


It is a common misconception that nuclear blasts go deep into the ground. In reality, the depth of a nuclear blast depends on the size of the bomb. The larger the bomb, the more damage it can cause. However, the vast majority of people who want a fall out shelter or bunker would not need to worry about this because the chances of a direct hit are extremely unlikely. Being within the radius of the blast is the more likely scenario, which hopefully will never happen.


Therefore, it is important to be prepared for all possible scenarios, no matter how unlikely they may seem. nuclear blasts are just one example of why it is always better to be safe than sorry.


Nuclear blasts can cause extensive and long lasting damage to people, animals, and the environment. They can contaminate water supplies, destroy crops, and damage buildings and other structures. People exposed to radiation from a nuclear blast can develop serious health effects, including cancer and other diseases. It is important to be prepared for a nuclear blast by having an emergency plan and supplies in place. In the event of a nuclear blast, remember to stay calm and follow your emergency plan.


If you are serious about protecting your family in the event of a nuclear attack, then you need to start planning you’re shelter today. Get started by gather the materials you  will need, and then start building your very own concrete bunker.


When the nuclear bomb goes off,  you will not have alot of time to find shelter. Having a game plan in the back of your mind of where you would go is essential. You will only have minutes and depending on how close you are, seconds.  The further underground you are, the better chance you have of surviving. 


Nuclear Attack


Nuclear attack is always a possibility. Whether it’s due to global conflict or the actions of a single individual, the threat of nuclear war is real and present. While the chances of a nuclear attack are relatively low, they are much higher if you live in a big city. Suburban and rural areas are less likely targets, but no area is completely safe. City living comes with its own risks, but the proximity to potential targets makes the risk of nuclear attack much higher.



The best way to protect yourself and your family is to be prepared. Learn about nuclear safety and have a plan in place in case of an attack. Knowing what to do makes all the difference when most have never given thought to it. So hopefully you can answer the question of “how far underground do you need to be to survive a nuke?”.It is always better to be prepared thank to be caught unprepared!
