Emergency Nuclear Filter and Bunker setup. (Preparation for nuclear attack)

Things that you may need to think through before a nuclear attack or accident. Bunker and filter considerations for protection before, during, and after a nuclear event.

Some comments: 1. have your decom space 90 degrees from your bunker entrance since Gamma radiation only travels is straight lines and cannot reflect on walls or deflect. 2. You don't have to store everything you need inside of the bunker area. You just need enough food water for a couple of days, since the radiation levels will drop significantly after the first couple of days. If you have a basement fallout shelter, you can store a lot of water & food the unshielded area outside of your basement, and make a very brief excursion outside of your shelter into the basement to grab additional water, food, or dispose of waste. 3. For waste disposal. some 5 gallon buckets will work. You can make a simple composting toilet with some saw dust in a 5 gallon bucket with a lid. You can use a 5 gallon pail liner bag so when you need to change it its just a matter of sealing the bag, and throwing outside of your shelter, You could store a few bags with saw dust, and just replace as needed. 4. You should have a gieger counter or dosemeter in your shelter so you can monitor radiation levels. so you have idea when its safe to leave, even for short excursions to throw out trash, or bring in additional supplies stored in your basement. 5. I would probably plan on sheltering indoors for a couple of months. Even if the radiation levels drop to safe levels, its possible that burning cities & rain will carry toxic smoke, ash & gases very long distances. I recall after 9/11 I crossed the Hudson river using the Newburgh-Beacon bridge a couple of days after the planes hit, and there was a strong smell of the smoke from the fire. The bridge is about 30 miles away from WTC, but I could see the black smoke column rising high up into the sky. I would imagine a nuclear war would be a million times worse than the WTC fire.

Good info. The important idea is to plan ahead and have your area and back up areas throughout ahead of time. These will all be different for each situation. And practicing will show areas you may need to work on. At least a walk through where you take inventory and review all the items you may need and setup required.

1 - and helps to break the air pressure. All pro shelters/bunkers with side (not top) entrance are built this way. - 5 the toxic smoke, soot, and VOc from damaged / blasted / burnt down buildings and chemical plants, storage, is a long term threat. 1 year (with cleaning!) from the burnt down lub plant in rouen 3 years ago, pollution from the plume up to 100 miles away, and toxic fumes (called bad odors by officials) for one year long on the city.

Since radiation will be from the dust in the air, you should place the filter inside the house to protect it from damage from the exterior such as blast or wind-blown objects! The house itself will act as a pre-filter if it is relatively air-tight! I don't think you can rely on having electrical power after a nuke attack because the EMP will probably knock out the grid! I would keep as much supplies as possible in the bunker because all the supplies outside may get contaminated! Your changing room should have a shower and drain since soap and water will wash off most of the contamination that may be on your body! Thank you for the video!

[@edwardjackson9791]

All good ideas. One thing to consider is if the filter is in the house you will be pulling contaminated air into the area where the filter is located. So that area may become more contaminated. Yes you will likely need a manual bellows or fan in case you lose power. However the filter is not just for a nuclear event so you may have power available.

[@RealitySurvival]

All good stuff. Im am wondering if having the filter inside would actually bring fallout into the house. I say this because the pressure would be exactly equalized. You would essentially be recycling the air. Meaning that the filter is sucking in with the exact same amount the it is blowing out. Just seems like the system would be much cleaner if it was being run from the garage (like you mentioned) or from a higher level in the house.

[@edwardjackson9791]

Running the filter inside does have advantages but you do risk drawing in some fallout. One thing to think of is it would be best if you can maintain a slight over pressure in your shelter. Wind pressure on a building will cause a differential pressure and force some contamination into the building. A slight over pressure about .25 inch water will help reduce infiltration and to achieve that you have to bring air in from outside your safe area. Of course you may not have power or means to provide that over pressure. The other thing is where ever you bring in the radioactive contamination that area will possibly become a high dose area and could raise the radiation levels in your shelter. All this being said you have to make plans based on your particular situation. Better to have a plan before an event than trying to think up one on the fly.

[@RealitySurvival]

@@edwardjackson9791 Yeah I totally understand the reasoning. I am just not sure the juice is worth the squeeze. I say that because most fallout is heavy. Im not sure that the system if placed in the middle of the home would be capable of causing any negative air pressure. The other thing that concerns me is that if the filter breaks or looses seal or something like that you could have a huge problem and would inadvertently be bringing fallout dust directly into your bunker area. Seems to me the rush is smaller having it in the home. But like you said it is good to think about things ahead of time. Personally I don't think I would run any air filtration system at all. Just don't think it is necessary. The reason that purpose built bunkers have them is because they are buried and they need air flow from outside to survive so of course it makes sense to filter it. But for above ground homes it isn't really needed. again just my take. I do applaud your efforts to get people thinking though and don't think you are putting out bad info by any means. Take care!

[@guytech7310]

Ideally you can place some HVAC filter on the outside to trap most of the large fallout particles. and have the filter with the Carbon & Hepa inside the shelter in case you need to fiddle with it. For the first few days even a very limited exposure (seconds to minutes) can be lethal or enough to cause radiation illness. Better to risk some exposure than have no access to filter system. Alternatively you can run two filteration systems: one with the filter on the outside and a backup inside. I would recommend using two vent ducts: one for each filter system. "Im not sure that the system if placed in the middle of the home would be capable of causing any negative air pressure." Its not the system that will cause negative pressure, its that you want the filter system to maintain a positive air pressure inside of your shelter to prevent gases like Iodine-125/131, Xe-135, Kr-90, from getting inside which you might inhale. As well as possible non radioactive toxic gases from burning materials like PVC.

[@tooshieg2059]

Rather than to seal the bunker airtight, I would create a positive pressure in the bunker, thus preventing radiated particles from entering. Also, filtered air inbound is able to replace CO which is able to escape. Make it small enough to run from battery power, recharged via solar or genny.

[@edwardjackson9791]

Correct, it would be difficult to make it air tight and if it were you would definitely have to monitor the CO2 levels and have a way to exchange the air. A manual air pump could also be in the design.

[@ncamp2126]

Check out organic air hepa filters. They are pricey at time of this post run about 100- to 130. They are washable and come ready to connect to a 4in abs pipe.

[@edwardjackson9791]

That is pricey. The one I used was around $30. But it depends on your needs and design. Thanks for the comment 👍

[@anitaleroy9442]

Thanks for the detailed and accurate / realistic tutorial.

[@edwardjackson9791]

Thank you for the feedback👍

[@DoctorSuezz]

Your door or entry way should be on a 90° angle. I appreciate your video and information. Thank you.

[@edwardjackson9791]

Thank you for your comment. You are correct if possible and at a distance also would reduce exposure. Each situation will need to be evaluated based on the physical consideration of the shelter.

[@anitaleroy9442]

Pro (expensive) bunker shelters are designed this way, yes.

[@edwardjackson9791]

@@anitaleroy9442 there is a book called “Nuclear War Survival Skills”, written back in the day, that has shelters you can build. They are temporary emergency shelters and require sweat equity to build. Look on line for the book. There are free PDF copies you can download. Thanks for the comment.👍

Around 20 years ago I added a room onto my house. 15 x 16, It has 8 in solid concrete walls and a 7 in solid concrete ceiling. Has roll up electric steel door going to the out side. I live in the sc coast. It’s a hurricane room. It’s almost air tight. I worked at a nuclear power plant and learned a lot of info about radiation. Now this room I have was not built for radiation but I believe with a little adjusting it it could be a good place to protect our selfs for a couple weeks. I enjoy your videos.

[@edwardjackson9791]

That’s great. We did something similar. We built a concrete house. Walls with 8 in concrete 2 1/2 inch styrofoam inside and out. Our garage has a 25 x 25 ft basement under it and an F5 storm door. We live in a tornado area in Midwest. Pretty much air tight. What plant did you work at? I was at DAEC.

[@freegrazer]

@@edwardjackson9791 I worked for a major elevator company and worked as a out side contractor on the elevators at Oconee nuclear power station In Upstate SC. The three reactors has one elevator in each one. Then one elevator in rhe auxiliary buildings . I worked there In the 70s and early 80s. After that I moved to coastal SC. I been preparing for a long time but for hurricanes.

[@edwardjackson9791]

@@freegrazer we had one elevator in the reactor build and when it was out it was bad. When I was an in plant operator we would often fix the elevator ourselves, which I’m sure was probably iffy. Mostly it was the doors not working properly and causing the elevator to stop going up and down. The elevator repairmen were always a welcome sight.

[@TheGhostfourthdragon]

What happens to the carbon dioxide inside the bunker. Better yet how do you do away with ?

[@edwardjackson9791]

I have a monitor that I use. They are relatively inexpensive but unless your bunker is very tight it will probably be ok.

[@JoeSmith-vs5sy]

Fail!!! House falls on bunker from explosion. House catches on fire you are toast..

[@edwardjackson9791]

Most homes will not be near enough to be damaged during a nuclear explosion. The explosions, although destructive in the immediate location, do not affect that large of an area. Maybe a 10 mile radius. You are much more likely to be affected by the fallout that can cover hundreds of square miles. But if you are unlucky enough to be experience the actual blast that could topple your house, you are probably toast no matter what you do.
