How to survive in a nuclear explosion

Written by team

Some politicians are mad and can go to the most extreme measures. Therefore, if this happens, everyone should be ready – that’s why everyone should have a kit for survival at home in a nuclear explosion.

What happens during a nuclear explosion

If you hit the epicentre of a nuclear strike, do not count on survival. A 1-megaton hydrogen bomb will create a massive crater at the site of the explosion. Within a 3-4 km radius, everything will turn to ashes and be destroyed.

With the explosion of a nuclear charge, the temperature at the epicentre will reach 500,000,000 ºС, evaporating everything. People who are 7-10 km away from it will disappear.

There will also be other unpleasant consequences that make survival from the use of nuclear weapons unlikely. Theoretically, surviving even close to the centre of a nuclear explosion would be possible. You will need a bomb shelter, which should be underground. However, when discussing atomic survival kits, we usually discuss survival after nuclear fallout.


The biggest threat to survival is radioactive fallout. Nuclear fission creates many types of radiation. None of these is “safe, ” but gamma rays and neutrons are the most problematic.

Gamma rays and neutrons are much more lethal than an actual nuclear explosion! Over time, they will kill more people, including those far beyond the explosion site.

In the event of a ground explosion, particles of the earth become radioactive and are ejected into the sky, forming a mushroom cloud. These radioactive particles eventually fall to the ground, hence the name precipitation.

A nuclear bomb exploding in the air is much worse than a ground explosion. It will not produce an ominous mushroom cloud, but radioactive particles will be released into the air. The wind carries them, and they fall to the ground in a much larger radius.

Consequences of radiation

Precipitation exposes us to radiation. This radiation causes changes in our cells at the chemical level, altering the DNA.

This can lead to problems such as:

  • Nausea and vomiting
  • Pride
  • Hair loss
  • Cancer
  • Congenital disorders in children
  • Infertility
  • Radiation sickness (leukemia)

Lethal doses of penetrating radiation:

3-4Gy – damage to the bone marrow within a month after irradiation; death is possible in 50% of those irradiated (without medical intervention).

Over 7 Gy (7000 mSv) (616 roentgens) is a highly severe form of acute radiation sickness.

Potassium iodide tablets

Potassium iodide is a salt. When taken, it floods the thyroid and prevents it from absorbing radioactive iodine. Therefore, potassium iodide tablets will protect you from thyroid cancer and other thyroid diseases due to precipitation.

But potassium iodide is not a magic pill against the effects of precipitation! It only protects the thyroid and will not cover the rest of the body from absorbing radiation.

It would help if you had potassium iodide tablets as part of your survival kit – don’t think you can take them and then walk through the radiation safely.

Protect yourself from the consequences

The most important thing to remember about surviving a nuclear fallout is not to run. Although it goes against our instinct, the amount of precipitation in the air is the highest immediately after a nuclear explosion.

If you immediately go on the run, you will expose yourself to high radiation levels that can quickly kill you.

On the contrary, if you seek asylum, you can avoid most of the consequences and remain safe.

It would help if you hid underground or in the centre of a tall building as deep as possible. The goal is to shelter from the effects of radiation with as much material as possible, made of concrete, brick, soil, etc. The material is a barrier through which the radioactive particles must pass.

How long does radioactive fallout last

Unfortunately, there is no good answer to the question of how long the fallout health threat will last. First of all, because there are not many studies on this topic. Second, the timing will vary depending on the size of the explosion and factors such as the weather.

In general, radiation will exist for many years but will not be the same as when a nuclear projectile explodes. The biggest threat occurs during the first two weeks. After two weeks, it will drop to about 1% of its original radiation level.

nuclear explosion Radiation Damage Radius

During testing, the explosion of a 15-megaton nuclear bomb caused radiation pollution 35 km upwind and 550 km downwind. This was during ground tests. An air burst would cause the fallout to cover a much larger radius.

Again, there is no exact way to calculate the radius of radiation contamination from a nuclear bomb. We cannot predict the bomb’s size or the wind’s direction and speed.

It may seem overkill, but the OPC will help protect you from radiation when it’s time to get outside.

What you need to know is to stay put as long as possible. When it’s necessary, or the authorities tell you to evacuate, get away from the blast zone and get out quickly!

It may seem like overkill, but consider purchasing a special protective suit. The Combined Arms Protective Suit (CHA) will help protect you from radiation when it’s time to get outside. 

nuclear explosion Survival Checklist 

Even if you’re not worried about surviving a nuclear attack, you should still have an emergency kit in case of hurricanes, earthquakes, power outages, and other disasters. Also, it would help if you had an emergency plan.

Nuclear blast survival kit items are specifically designed to protect you from radiation. Please don’t wait until it’s too late to prepare for the apocalypse.

  • bottled water
  • Non-perishable food
  • Dedicated shelter
  • emergency radio
  • emergency heating
  • emergency toilet
  • OK
  • Geiger counter (helps you know when it’s safe to evacuate )
  • Mask
  • Change of clothes (in case of infection)
  • Gloves – for working with any contaminated items. 
  • Sealed bags (for contaminated items)
  • Soap and a way to cleanse yourself
  • First aid kit

Survival nuclear explosion

  1. Shelter
  • Build an underground survival shelter if you can.
  • Set up a hiding place in your house or apartment’s basement or an inner room.
  • If you can’t build a shelter, find out where the nearest bomb shelter is.
  1. If you are not at home
  • Make a list of potential hideouts near your home, work, school, and other places you frequent.
  • Don’t try to pick up your kids from school – that will only expose you and them to even more exposure.
  • Cleanse the entire body (including ears and nose) with soap and water to remove contaminated particles. Do not use conditioner or skin creams, as these will bind to radioactive particles.
  1. Evacuation
  • Use the emergency radio to know when it’s safe to evacuate
  • Do not leave your hideout under any circumstances for the first 24 hours.
  • After 24 hours to 2 weeks, it should be safe to evacuate to a location upwind.
