Nuclear Suburbia
While my modus operandi has been to largely ignore the type of disaster until it actually happens, there has been concern that New York City would be a terrorist target, . . . again, with the terrorists using a dirty bomb, or an actual nuclear device if they can get one.
Since New York City is a commutable distance away, I believe this possibility is one I need to consider. A single nuclear blast in New York City would not result in destruction of my home, but would probably leave us with a serious fall out problem, making Uncle Paranoid, well, paranoid.

Nuclear Prepping: First things first.
The first question one will have regarding fallout is whether it is actually occurring.
Well, is it?
Fortunately, there are these things called Geiger counters. You’ve probably seen them in old movies and such. Thousands, perhaps millions, of them were produced back in the 50’s and 60’s when the country took the possibility of nuclear war seriously.

Also fortunately, they were built to survive a nuclear war. These things are indestructible. They are still around. You can get a refurbished 1960’s era Geiger counter for a modest sum. They take D cell batteries, so pack one Geiger counter away in a 50 caliber ammo can, converted into a Faraday cage, and toss in a fresh pack of D cells, ready to be installed in the Geiger counter.
They fit perfectly in the 50 caliber can with just enough space for some cardboard to convert the 50 caliber can into a Faraday cage.
The model you want is model V-717. When in use, V-717 lets you place the sensor outside, while the unit itself is inside, connected by a cable. You can sit safely in your bunker, checking the sensor readings from outside.
Your other alternative is look in the direction of your nearest major city for one of these:

The nuclear bunker mentality
This raises an interesting point. Bunker? What bunker? How am I going to build a bunker? Will the wife react like she did with the generator, or the BOV? Will she think it was a worthwhile purchase after the nuclear clown lands on our house? I absolutely had to figure this one out before Murphy did. Otherwise the New York financial district was doomed!
It turns out that radiation diminishes as it passes through material, so putting a few feet of earth, concrete, etc. between you and the radiation diminishes it to safe levels.
What is not so obvious is that any material will diminish the radiation, albeit the denser the material the better the effect. Water works. Wood works, just not as good as concrete or steel. Paper, e.g. books, are surprisingly good.
Think outside the box
There is nothing that says your bunker needs to be built as a box underground. In addition, Peoples Republic of New Jersey houses almost always have basements. A typical basement will put you partially underground, leaving you with the problem of protecting yourself from what is directly overhead.
If you are on the side of a hill, the earth surrounding your basement may be higher on one side of the house vs. another, so you may also need to worry about radiation from one side. Typically one will probably have a couple windows high on the basement walls. Block them with whatever material is handy. Overhead one will have a couple floors of house and an attic.
Bunker supplies
If you’ve been following my series, and following my footsteps, you have about 1,000 cu. ft. of food and a couple hundred cu. ft. of dog food, or at least plan to have it. You have furniture and other household stuff. You also have a whole bunch of 50 caliber cans with various stuff in them and they stack neatly.
Ammo would be perfect, (lead and other metals) but you don’t need ammo for the recommended Peoples of Republic of New Jersey firearms, so just pack all those ammo cans full of Geiger counters if you don’t have enough ammo.
Required additional material, with this starting point, is a few sheets of thick plywood.

How they did it in the good old days!
The Plan
My plan is for a quick and dirty shelter assembled in my basement, per the 1950’s approach. First on the floors above the basement, move all furniture and other material against the exterior walls, especially above where you intend to create your bunker. Now move to the basement and toss the sensor end of a V-717 out the window, and close the window. Move stuff to the outside walls as was done on the first floor. We are now ready in our open basement floor space to build a bunker.
I need to create walls that will support a heavy ceiling out of what is handy. I could have actual building materials, or just arrange all those 5 gallon buckets into walls. 8 ft. x 8 ft. is a handy floor size if you are working with plywood or other standard Home Depot stuff. I’ll make the box about 6 ft. high. Toss a few sheets of heavy plywood on top, and then stuff onto the plywood ceiling. I’m thinking 4 sheets of ¾” plywood in two layers atop an 8 ft. x 8 ft. space.
That leaves me with about 2 feet of space above the box, and below the basement ceiling, in which to place as much material as I can. If I can cover the whole box with 50 caliber cans, especially if they are full of ammo, that is going to be a pretty dense roof. If I don’t have that many ammo cans, I can use whatever material I have, like 5 gallon water jugs or dog food.
Now that I have space…
I now have a room within my basement that is covered with a lot of overhead material, both from the box and on the first floor of the house, and the only construction cost was a few sheets of plywood and some sweat equity.
I can now get into my newly constructed food bunker, along with other people and The Jersey Boys, and avoid going outside. Duct tape on windows, etc. is also recommended. You can do the same thing if you have a basement and a bunch of easy to rearrange material. The denser, the better. How many feet of white rice will protect us adequately? If you find an answer, let me know. I’m just going to use all I have.
OK, you are good to go…
Now you are ready for a lone nuclear strike against your nearby city. You are not ready for nuclear winter, nor the other effects of all out nuclear war, but the lone strike against a nearly city, or an accident at the local nuclear power plant, could be survived with this plan. However, you need to pretty much stay in your box, er, bunker, until it is safe to emerge.
When is it safe to emerge? What does your Geiger counter say? If you like the Geiger counter idea, I recommend two, but not for the usual two is one and one is none idea. If you have one with the sensor outside and another with the sensor inside, you can determine both how bad your surroundings are, and with your second Geiger Counter, keep the sensor inside to see how well your box, bunker, whatever, is working at keeping you protected.
Now you may be thinking that 20 people aren’t going to fit in a 8 ft. x 8 ft. box. However, in this scenario I doubt all will show up, due to lack of warning and time. If they do show up, it will be after the radiation levels are down. If I am wrong, then I may need to build more than one box in the basement. All I need is more “stuff”.
Anyhow, that’s my plan and I am sticking to it, at least until I can think of a better one.
Parts of this article have appeared in a previous article which this expanded one supersedes.

A good resource for nuclear survival info is the FM 21-76 US Army Survival Manual (Chapter 23, Survival In Man-Made Hazards). Lots of good info. I was surprised how short the ‘hunker down’ period was. Basically two weeks, but you can have limited exposure after 3 days (short period, must remove and decontaminate clothes, blah blah blah).
Another option for a Geiger counter are the RadTriage badges. They measure cumulative exposure. Not as good as a Geiger counter, but may be more readily available.
If you actually want a Geiger counter check e-Bay. They’ll last forever and they are cheap.
Wouldn’t the water & foodstuffs you use as barriers be contaminated?
Most contamination after a nuclear blast is in the form of particulates – dust particles resulting from the explosion, with each dust particle being radioactive. Much of the radioactivity shed acts only over a very short distance to affect live tissue.
It varies by type of radiation, but the general rule is that it’s contact with (including inhalation of) the radioactive particles that produces the most exposure. If you clean off everything carefully while protecting yourself from the dust, the stuff inside the containers would be fine.
Spice has this covered. I’m talking about packaged food, e.g. 5 gal buckets, etc. If you want to use it, just don’t ingest fallout particles. Having used a 5 gallon bucket as a barrier inside your home should be no problem as long as fallout has not invaded your home.
Remembering that twilight zone show “The Shelter” I expect that it’s not the event so much as I can prepare for it. It’s the reactions of scared, angry folks I cannot prepare for very well. Radioactive dirt contaminated folks forcing themselves into your shelter will make a bad situation worse both short term and long.
Please remember to use plastic sheeting to cover any broken windows as to reduce the amount of radioactive dust landing inside your home. Time, density and distance reduces the effects. Fallout on your roof vs. your living room floor just above you greatly affects the amount you have to shield against in your homemade shelter.
All this makes that earth sheltered tractor shelter look pretty good eh? Some tarps and sandbags and your shelter is pretty solid. Some folks I know used a false wall of concrete filled blocks and such to make a hidden shelter in their basements. A job you can do yourself given a concrete floored basement you just have to think out how your going to access it in a concealed manner.
Spice I don’t know if you’ve done an article about Dirty bomb vs. Nuclear explosion. A dirty bomb is an explosive device that scatters radioactive material around. A Nuclear weapon is an nuclear explosion that depending if the fireball touches earth Ground Burst or low airburst generates a powerful shockwave and flash blinding for a huge radius as well as sucking material up into the famed mushroom cloud to be irradiated into what is later fall out.
If you think of radioactive material as little hot coals the dirty bomb scatters very heavy hot coals often with half life (time until half of the radiation fades) of decades or worse over a fairly small area.
An airburst Nuclear strike scatters various sizes of hot coals with the heaviest quite nearby the strike down wind mostly (affected by various levels of wind directions as the mushroom cloud climbs) and the further your away from the strike the less fall out you get. Most irradiated fallout material has a half life of a day or so thus the Civil Defense plan for two weeks under shelter before short ventures out to dump toilets and such.
Inside your shelter you need to think about 2 weeks plus water, food and MOST important Sanitation as all that food and water will come out again and you have to deal with it. Would be harsh to have enough shielding to survive the radiation and suffer or die horribly from poor sanitation.
Most effects of a nuclear strike are survivable if you survive the initial blast-shockwave and know what to do NOW. Nuclear winters from a huge exchange is a different subject.
Michael, the subject of a dirty bomb has never come up to my knowledge before on 3BY… it’s something I haven’t looked into (and I can’t speak for her but I suspect it’s something she hasn’t either).
It is, however, an interesting topic and I’m going to put that one on the “to do” list.
From what I have studied, a dirty bomb is more of a ‘terrorism’ thing meaning it is intended to create more havoc than the act itself warrants. I think the political aspects are just as real and potentially destructive as the event itself.
There are several practical prepping aspects related to a dirty bomb situation. Understanding the mechanics of how contamination spreads is important and overlaps with other potential hazards which might make it a worthy topic of consideration. I see two benefits: 1) it will help those in the immediate vicinity prepare for the event and know what the real concern is, and 2) it will bring peace of mind to everyone else. On that aspect alone, I think an article on the subject of dirty bombs is important.
Thank you for the suggestion, Michael.
A dirty bomb is definitely a NYC risk. The area impacted would be more compact than if there were a nuclear blast, but the idea of one being set off in the financial district got a lot of attention post-9/11. If the area affected was similar to the area impacted by 9/11, but left a more toxic cleanup to be done, it would definitely screw things up in New York for a prolonged period.
