The unpleasant truth is a nuclear attack or radiological emergency can cause significant damage and casualties that stretch for miles surrounding the blast zone. Not only can the explosion and blast wave be extremely dangerous, but the radioactive fallout and electromagnetic pulse caused by the nuclear blast can also wreak havoc on people, buildings, and the environment.

To ensure that you and your family are safe from intentional nuclear attacks, accidental nuclear explosions, and power plant meltdowns, we have compiled this nuclear survival kit guide. We will explain what your nuclear survival kit should include and offer some tips for what you should do to stay safe and avoid significant radiation exposure!

What Is a Nuclear Survival Kit?

As the name suggests, a nuclear survival kit is an emergency kit that contains necessary items you and your family will need to sustain yourselves during the first 72 hours following a nuclear incident.

The items in a nuclear survival kit help you hunker down and stay safe from the many hazards of a nuclear explosion, including fallout and radiation. One of the most important things following a nuclear explosion is to hunker down and stay indoors. Once it is safe to do so, the government will issue an evacuation order and relocate you to a safe location.

Your nuclear emergency kit is designed to help you survive and stay safe until that evacuation order is issued.

What Should Your Nuclear Emergency Preparedness Kit Contain?

Nuclear Survival Kit with Non-Perishable Food Items

While you can make additions to your nuclear survival kit to cater to your unique needs, the following items are must-haves in any kit:

Potassium Iodide Tablets 130 mg EXP 10/2025 Kosher Iodine Tablets , Thyroid Supplement – 2 Pack | 120 Tablets Total
  • ☑️ Pure Ingredients: Potassium Iodide is a stable form of iodine. Potassium Iodide 130 mg per serving is an essential supplement to keep in your medicine cabinet in case of emergency survival situation.
  • ☑️ Thyroid Supplement: Potassium Iodide tablets are an affordable and effective way to support iodine deficiency. Ingesting small amounts of stable Potassium Iodide, or KI, can saturate the thyroid gland. We pack each tablet with pure potassium iodide to ensure maximum effectiveness and proper potency. Potassium Iodide is a must have in your survival gear bag.
  • ☑️ Once Per Day Solution: Easy to swallow Potassium Iodide tablets are a quick once a day solution just like many other forms of KI pills but without the nasty after taste like liquid iodine, iodine tinctures, nascent iodine drops, liquid potassium iodide supplement, pure iodine salt, potassium iodide powder.
  • ☑️ Suggested Use: Use only as directed. For short-term use only (up to 10 days). Adults and adolescents: up to 2 tablets once daily. For children ages 3-12 years up to 1 tablet once daily. For children 1-3 years 1/2 tablet once daily. For children under 1 year consult your physician before use.
  • ☑️ EXPIRATION: 07/2025
  • At least a 72-hour supply of bottled water for each of the members of your household
  • A three-day supply of non-perishable food items for you and your family (energy bars, nuts, and seeds, canned vegetables and meats, canned beans, vitamin pills, etc.)
  • Emergency radio with a hand crank
  • A change of warm clothes and blankets
  • A basic first aid kit (alcohol pads, bandages, hold and cold packs, medical tape, sanitizer, tourniquet, gloves and eye protection, suture kit, medical scissors, tweezers, basic pain medication, etc.)
  • Soap that you can use to scrub yourself clean
  • Emergency masks for each of the members of your household (preferably tight-fitting N95 masks) 
  • Flashlights and headlamps with spare batteries
  • Properly fitting hazmat suits for yourself and your family members
  • Sanitary items (toilet paper, toothbrushes and toothpaste, hand sanitizer, sanitary wipes, etc.)
  • A map of your city and the surrounding area, as well as a compass 
  • Potassium iodide tablets, which you can purchase many places, including Amazon.com (protects the thyroid from absorbing radiation)

What Else Can You Keep in Your Nuclear Survival Kit?

While the items mentioned above should be in any nuclear survival kit, yours can also include items unique to your needs. These could consist of specific prescription medications that you or a family member must take daily.

You could include items that are specific to the climate where you live. For example, if you live in a colder climate, you may want to put aside winter clothing in a sealed bag. Those in warmer climates might also require more bottled water than those in milder regions.

If you have pets, you could put aside non-perishable food for your animals in sealed and safe containers. Some will also keep a gasoline-powered generator in their designated shelter area and spare gasoline for the generator and their evacuation vehicle. A portable shower with an adequate supply of clean water can also be helpful, as it allows you to wash away potential contaminants from the surface of your skin.

As long as you have everything you and your family need to survive for at least 72 hours, you will be more prepared for a nuclear disaster than a significant proportion of the population.

Where Should You Keep Your Nuclear Survival Kit?

Ideally, you would keep your nuclear survival kit and other supplies in a dedicated nuclear fallout shelter in an easily accessible location.

With that said, not everyone has the type of property or living arrangement that could accommodate a dedicated nuclear fallout shelter. In this case, the main thing would be keeping your nuclear survival kit in a safe location that you could access with minimal warning.

For many, this is a basement or a closet in their house or apartment. The last thing you want is to need to run outdoors to get your nuclear survival kit. This also means it should not be in your vehicle unless you spend significant time on the road.

It is also important that all of the items in your nuclear survival kit are protected from radiation, meaning they are in sealed containers. Even when using items in sealed containers, such as bottled water, you should still wash any portion of the container that will make contact with your bare skin.

What Should You Do in the Event of a Nuclear Incident?

The first thing you should do if you are warned about an incoming nuclear emergency or attack is take shelter immediately. Even if you have no warning, you should get indoors as quickly as possible, as even people many miles from the explosion could be at risk of exposure.

Next, you should clean your entire body with soap and clean water. Do not use skin creams or conditioner on your hair. Simply use uncontaminated water and plain soap. Once you have changed into clean clothes and thoroughly washed, you must remain sheltered and await further instructions.

This is why it is so important to have an emergency radio in your nuclear survival kit. Government or military officials will update you with the most appropriate instructions, which could include relocating to a safer area within 24 to 48 hours of the incident.

When the evacuation order is issued, follow the instructions carefully, including where to travel. This is because the evacuation instructions will almost certainly account for wind direction to keep evacuees as safe as possible from radiation exposure.
