Bomb Shelter Guide

Welcome to undergroundbombshelter.com! You’ve probably come to the Underground Bomb Shelter site because of your concern for an impending nuclear attack. Considering the efforts of certain dictator-led countries in the Middle and Far East to obtain nuclear weapons, who isn’t on edge?

You’ve come to the right place. Rest assured, you can survive a nuclear attack. It will not be the end of the world. But you must be prepared!

Atomic BombTake this into consideration: those within 2-3 miles of ground zero will not fare well. This is an unfortunate reality, and the best you can do is plan not to be near enough to a target site. Are you living in a nuclear threat area that will be effected by the initial blast? After a nuclear detonation and passage of the blast wave, the next greatest loss of life is a result of radioactive fallout, which can drift for hundreds of miles downwind. However, after just a few days the level of radioactivity will drop to non-lethal levels.

Forget any notions of a nuclear holocaust and start planning for survival.

What Will A Nuclear Bomb Actually Do?


Lacking any experience with nuclear weaponry, it can be difficult to picture the damage caused by a nuclear bomb. Consider the following:

If, for example, a 50 kiloton bomb was detonated on the surface of the earth (as opposed to in the air), you would need to be at least 2 miles away from ground zero to survive the blast wind. At or near 2 miles from ground zero, the speed of the blast wind would drop from about 2,000 mph to 60 mph. A mile from ground zero the blast wind will have the power of a category 4 hurricane: about 170 mph. All but the very strongest of structures would be leveled as the blast shot out and then sucked back after a few seconds. For survival, distance is key: the blast wind would drop to about 30 mph at a distance of 3 miles from ground zero, and down to 0 at about 4 miles away. You can expect many fires in the surrounding radius as a result of incendiary debris being thrown out by the blast wind.

Within half an hour fallout would start arriving up to 10 miles from detonation. At just 50 miles, you would start seeing fallout after about 3 hours. It would take about 5 or 6 hours to reach 100 miles out. Lethal doses of radioactive fallout would be present 10 miles out for a least a week. By week two, most locations downwind would see levels fall to survivable rates. Anyone within 10 miles would be required to stay sheltered for at least a month to ensure complete protection.

These hypothetical numbers are high: a terrorist would likely use a 1 or 2 kiloton bomb, such as the one detonated underground by North Korea in October, 2006. If it’s possible to survive a 50 kiloton nuclear detonation, how much more so to survive 1-2 kilotons! And even more so if you are prepared.

Here’s How to Get Ready.

Are you ready for a nuclear attack? What would you do? Where would you go? All angles of nuclear threat preparedness are explored on this site.

Minimizing Exposure to Radiation

Nuclear bomb survivability chart key

The greatest concern for survivors of the initial blast is radioactive fallout. Fallout will kill as many, possibly even more, than the blast itself. Your exposure to deadly levels of radiation depends on three factors:




Your best defense is distance. If you are several miles or more away from ground zero, at best you can react to the bright flash of light. If you are immediately keen on what’s going on, you may have several minutes to reach the safety of your shelter before the blast wave arrives. This scenario applies not to people who are at ground zero (they will be long gone, of course), but to those who are between about 3 and 10+ miles away. They would have mere seconds to react.

Radioactive Fallout Will be The Killer

Like the more than 160 million Americans who live within the danger zones, your greatest concern following a nuclear attack is radioactive fallout.

Radioactive fallout is the main reason you will need a well-constructed, underground bomb shelter.

It’s true that taking shelter under the coffee table or in the basement will increase your chances for short-term survival, but only an underground bomb shelter will guarantee your survival. The concept is fairly simple – separate yourself from fallout with at least 36 inches of dirt (or varying amounts of other materials such as concrete, lead, etc.)

While the initial blast could kill a million people, tens of thousands more will die from radioactive dust which can drift for several hundred miles down from the point of detonation. The track it follows, just as in a volcano eruption, is one relevant to the jet stream, a prevailing pattern of winds and weather coming from the west or northwest. In other words, the fallout will most likely travel from west to east.

Multiple factors determine the level of radiation present at different intervals of time and distance from the blast. Included are weather, temperature, wind speed, and size of the weapon. Your best defense against fallout? A carefully planned, well-constructed, and fully stocked underground bomb shelter.

Get an Underground Bomb Shelter…Now What?

You’ve heard of bomb shelters but don’t have a clue as to how or where to buy one, or at best build a bomb shelter. There are several businesses and organizations in America which specialize in underground bomb shelter fabrication. You can have a shelter installed for as little as $20,000, all the way up to hundreds of thousands of dollars. Many similar businesses offer various products such as Geiger counters, radiation alarms, and underground bomb shelter filtration devices to complement the wise shelter owner. There are countless others offering survival meal packages, books about nuclear blasts, specialized emergency preparedness kits, and even plans for building underground bomb shelters.

The important thing to consider is that you are going to need more than just a container in the ground if you expect to survive. Waiting until an attack has occurred would not be the ideal time to realize you are lacking a blast valve, filtration kit, or even toilet paper! You are going to need a complete underground bomb shelter plan that has been thoroughly scrutinized.

UndergroundBombShelters.com takes away all the confusion by providing you with a one-stop planning source for everything you need to survive. We tell you how to build an underground bomb shelter, where to get materials, where to place the shelter, and what to stock in it.

Here are just a few of the hundreds of very important issues that must be addressed when considering complete protection from a nuclear blast or other WMD attack:

  • What level of expertise does the business providing my shelter have?
  • What types of underground bomb shelters are available?
  • Can I build my own underground bomb shelter, and what materials will I need? Build Your Own Bomb Shelter
  • What will protect me and my family from the blast? Your Home Is Not Complete Without a Shelter
  • What will protect me and my family from radioactive fallout?
  • What will protect me and my family from a biological attack?
  • How long will we need to remain in our underground bomb shelter following an attack? Batten Down the Hatches: How Long Should You Stay In your Shelter?
  • Will a typical emergency preparedness kit be sufficient? The Nuclear Emergency Kit: A Shelter Must-Have
  • Will the shelter provide protection from radiological, biological or chemical agents?
  • What amount of food, water, and other basic needs should be stored in our shelter? Sample 2 Week Stay Budget
  • What is the best food to get? Long Term Food Storage
  • What do we do when nature calls?
  • Will I be able to purchase military-grade supplies?
  • What technical nuclear information should I have on hand inside my shelter?
  • Can my shelter double as a wine cellar or storage pantry?
  • What are the time requirements for getting my loved ones inside the shelter?
  • I can’t afford a professionally installed shelter. What should I do?
  • Will this be the end of the world? And if so, why should I be concerned about living?
  • What will $1,000, $5,000 or even $20,000 buy me?
  • How is electrical power provided in an underground bomb shelter?
  • How can I communicate with the outside world following an attack?
  • Will a Funeral Insurance plan help me in the event of a disaster?

Here’s some food for thought. Would you fight a fire with buckets or fire hoses? In a tornado, would you prefer to be in the bath tub of a mobile home or an underground cellar complete with emergency kit? If you are bitten by a diamond-back rattlesnake miles from nowhere, would you have someone slice and suck the wound, or use a snake survival kit? The point is that you should never bring a knife to a gun fight. Buying or building an underground bomb shelter is smart. But not knowing how to survive in one is a death sentence. You are going to need very thorough information. You are going to need a top-notch plan.
