What’s the best way to protect yourself from a nuclear explosion?

Build a bunker.
If you’re going to be surviving a nuclear attack, you need to build a bunker. To make sure your bunker is safe, it has to be far enough away from the blast site so that it doesn’t get destroyed, and it needs to have a very thick roof. As far as how big and deep your bunker needs to be, that depends on what type of fallout you’re trying to protect yourself from—ideally, you’ll want a lot more space for storing food and supplies if you’re planning for long-term fallout. You should also have some sort of ventilation system built in so that air can flow in and out of the bunker.
If you’re crazy rich or at least well off, then this might not seem like such an impossible task. But for average people who aren’t already building bunkers under their mansions, there are always other options (though they may not all be ideal). For example:
Go underground! The subway system is one possibility if a nuclear strike happens during off-peak hours; otherwise look into large department store basements or even sewers—the latter will require some finagling with ladders and ropes because they’re usually pretty shallow. You’ll want an airtight seal at the entrance using duct tape/plastic wrap/whatever else works best with whatever material(s) are available around where they live (i.e., not on roofs).
Find an abandoned mine shaft nearby where people could hide out until radiation levels drop back down again after detonation (or better yet–they’ve got plenty stored up for later use). These should already have good ventilation systems installed since miners were constantly working inside them so fresh oxygenated blood could flow through their bodies while performing arduous shifts underground all day long every day without any sunlight exposure whatsoever…this might be too much information but yeah think about how cool these guys were!
Put together or buy a personal radiation detector.
If you’re caught in the fallout zone, put together or buy a personal radiation detector.
There are many different types of radiation detectors. Some may be able to detect radiation within a 1-2 mile range, and others may be able to detect both alpha and beta particles, but not gamma rays. To get the most bang for your buck, look for a detector that is connected to a smartphone and can offer real-time radiation detection as well as store data and download later.
Create a decontamination room.
In my survival research, I’ve found that you’ll want to make sure you have a decontamination room in your fallout shelter. You can never be too cautious when it comes to radiation, and it’s good to have a plan set in place for how you will keep yourself clean. Here are some tips I picked up:
The ideal setup is an enclosed room with no access to the outside world. Take off any shoes before entering the decontamination room so that they don’t get contaminated.
Take off all clothes and any items on your body, like jewelry or watches.
Take a small container of water and soap into the decontamination room, along with a towel and change of clothes.
Use the water and soap to thoroughly wash every part of your body from head-to-toe in order to remove any radioactive particles that might be clinging to your skin. If this is not possible due to low water supplies, use dry paper towels instead of wet ones for better absorption capability—wet towels might spread contamination around more than dry ones would by drying quickly on contaminated areas instead of absorbing them properly. Be careful about contaminating other parts on your body while wiping one area clean!
After the shower or bath, change into new clothes if available but don’t put anything back on over skin until it has been dried completely so as not store moisture underneath clothing where radioactive material could still linger near exposed flesh and cause further exposure through prolonged contact over time (elevated risk). In extreme situations where there is little-to-no clean water left or no ability at all for bathing/showering/any other form of cleaning oneself–like during power outages–simply changing out clothing after being exposed may be enough protection against radiation sickness symptoms if done immediately upon exposure.”
Stock up on food and water.
The next step you need to take is stocking up on food and water. Experts recommend storing shelf-stable foods that won’t require cooking, such as:
Canned goods (fruit, vegetables, meat, fish)
Dried fruit
Jerky and other types of dried meat
Nuts and seeds
Peanut butter
Look for foods that are easy to prepare, don’t spoil easily and don’t require a lot of water. Safe Water Now recommends storing enough food for at least two weeks. You should also stock up on plenty of clean drinking water—at least two weeks’ worth. It’s important to store your water in sealed containers so that it doesn’t become contaminated with radiation.
Get a gas mask.
In a survival scenario, you’re going to want a gas mask. Gas masks are arguably the most effective way to protect your lungs from nuclear fallout, and are not as hard to acquire as you might think. You can purchase them online, but if the threat of nuclear attack is imminent, or if you’re just looking for an extra DIY challenge on your Sunday afternoon, there’s no need to rush out and empty your savings account.
You can make a gas mask out of household products like a plastic bottle and rubber gasket (if you’re feeling ambitious), or even just with a wet towel (if Armageddon is staring you in the face). Do some research online so that when the day comes that you find yourself sprinting down a crowded city street trying to escape an airborne mushroom cloud, you’ll be ready.
Pack communication devices.
Of course, what’s the best way to protect yourself from a nuclear explosion? You’d think it was obvious—take shelter and hide underground, right? But if we’re being honest, it’s a matter of preference.
You see, in this scenario you’re left with two options: choose to stay in your own home (most likely not an ideal location) or seek out alternate locations. If you’re on foot and carrying only a backpack and some water supplies, one option is to find an uninhabited area such as a mountaintop or nearby woods. These areas will provide good cover from the fallout cloud and offer protection from radiation exposure—but they might be off the beaten path for immediate search-and-rescue operations.
So you’ll have to consider how long you can wait before running into police or military units who may be searching for survivors.
With these points in mind, we’d recommend packing some communication devices (batteries included) that can get through radio waves without too much interference like solar-powered radios or walkie-talkies for your first option—because if there’s no communication with other survivors when search-and-rescue teams arrive, they won’t know where to look.

Gather portable power sources.
Rather than trust the government to provide you with a nuclear-proof bunker and adequate rations, you can put together your own mini power plant. Once you have gathered all the appropriate items for a portable power plant, it is wise to observe the following steps:
Purchase an appropriate battery pack. Your ideal battery pack will consist of at least one panel which is designed for solar energy collection and another for charging via wind. These should be connected by an inverter that converts AC current from your home’s electrical grid into DC current, which is necessary for recharging your devices while they are plugged into the battery pack via USB cord or other means.
See if there is any nuclear fallout in your area before setting up your portable power plant so that it does not get damaged or contaminated during use! If there isn’t any radiation present around where you live, then go ahead and install all panels needed to charge device (solar panels can be set up quickly). The last thing we want is our new gadget getting destroyed by radioactive particles while trying to recharge its batteries during an emergency situation like this one–so always make sure there isn’t any nearby before installing any kind of equipment outside.”
A nuclear blast is like no other disaster you’ve faced before, and it requires special preparation to survive it.
A nuclear blast is like no other disaster you’ve faced before, and it requires special preparation to survive it.
The biggest thing to remember about surviving a nuclear explosion is that a nuclear bomb is unlike any natural or man-made disaster you’ve ever encountered. Unlike hurricanes and earthquakes, which tend to last for minutes or hours at most, the after-effects of a hydrogen bomb can linger for days, weeks, months, or even years. A single nuclear blast can cause severe injury and death over an area as large as several hundred square miles.
The effects of such a weapon are so great that even if you are miles away from the center of the blast, you could still suffer severe injuries to your body and long-term radiation exposure.
We’ve talked about a lot of ways you can protect yourself from a nuclear explosion, but what is the best way?
The answer to that question may surprise you. While having a bunker and personal radiation detector are both excellent ideas, they might not be enough. If there is an atomic blast, it’s important to have a decontamination room set up in your home so you can clean yourself and your family off before heading to the bunker.
Always remember to not forget about food and water, you’ll need plenty of both to last for an extended period of time. Finally, make sure you have communication devices so you can stay updated on the situation. With these tips, you should be able to protect you and your family from a nuclear explosion.
