Three Related Disasters (Part 2), by Joe Refugee From Tokyo

Days Two and Three I slept well the night of 11-3-11, which was good, because I hadn’t the two previous nights. A premonition, perhaps? Like the day after September 11th, there was an eerie feeling everywhere. The weather was nice, at least in Tokyo, but a cold front was coming in from the North, so the folks near the Tohoku coast were going to be suffering even more. It was obvious that the damage was off the charts, but the television downplayed the likely deaths, and a big question was whether the government had learned from its poor performance during …


Useful Tidbits on Radiation and Journalists–The Season of Isotopes and Misanthropes

Many readers have been sending me questions about radiation. One, from a reader in Los Angeles asked: “Mr. Rawles, Should I sleep in my basement for the next few weeks?” Please don’t over-react, folks. I must state, forthrightly: 1.) The gamma emitters at the Fukushima reactors (and more importantly, their spent fuel ponds) are a long, long way from America. 2.) In my opinion, the only significant risk to health here in CONUS is possibly a chance that a bit of radioactive dust (with isotopes like Strontium-90 or Iodine-131) could end up deposited on pasture grasses and then subsequently become …


Letter Re: Misconceptions on CDV-Series Radiation Meters

Jim, There’s a lot of folks around the country who bought surplus Civil Defense radiation meters. What they don’t understand is the CDV-715, CDV-717 and CDV-720 meters WILL NOT measure background radiation and are useless if they are watching for increased radiation from Japan. Only the CDV-700 will measure background radiation. According to an LAFD document: “Radiological survey instruments, if available, are recommended for initial entry to the site. Before entering the accident area, determine the background radiation level using the CD V-700, or a similar survey instrument.” Background radiation levels cannot be determined using the CD V-715 or other …


Letter Re: Do-It Yourself HEPA Air Filtration for NBC Shelters

2

Friends, In the wake of the Japanese nuclear plant melt-down situation, I called a safe room manufacturer for a hand cranked air filter.  It was over $2,000.  Too much.  I did learn that you need both particulate (HEPA) and gas (carbon) filters.   I have jury-rigged an NBC air filtration system.  Here it is: Go to a hydroponics store or find one online.  Yes, the one’s that people go to in order to grow marijuana. You will need an inline fan.  I used a  continentalfan.com AXC150B-C fan.  It is a little more expensive but German engineering costs more.  (Quieter too). You …


Letter Re: Nuclear Incidents in Japan – The Truth and the Rumors

Hello James, It is with a heavy heart that I watch the nuclear incident unfold in Japan. I am watching my nightmare come true, and I pray for the safety of the people in Japan. As you know, my article that was published in your blog last September was primarily written to alert the public about the possible EMP effects on nuclear power plants. While the initiating event may have been different, the results of the loss of all AC power at the site results in virtually identical consequences. Events are playing out very similarly to those that I had …

Letter Re: Encapsulate Your Own Potassium Iodate

Dear Editor: With several Japanese reactors threatening to meltdown, knowing that I am downwind and would have less than a few days’ notice, I quickly did some research on how to protect my family. The choices for thyroid protection (apparently the most common disease) are either Potassium Iodate (KIO3) or Potassium Iodide (KI). I found an old SurvivalBlog article that showed that KIO3 has advantages to KI. So I placed an order for enough pills to cover our family, plus extras to give away. But while doing some additional research I happened upon the bulk form of KIO3 at PureBulk.com. I …


Some Experiences with Hazmat Cleanup, by Pat O.

I spent three years working through college as part of several emergency response teams dealing with hazardous materials (Hazmat) containment and cleanup.  There are simple lessons that can help prepare for various emergencies and materials that might be encountered.  This is not a do-it-yourself type of endeavor nor is it safe unless you are properly trained, equipped and monitored.  Safety is most important and your responsibility: Never put yourself or others in danger when a substance or environment is unknown or dangerous.  Take basic precautions and obtain all information about any potentially dangerous materials you may encounter or store as …


Letter Re: Storing Spare Vehicle CPUs for EMP Preparedness

Mr. Rawles,   I recently have been going through the PCM/ECM/ECU vehicle engine/transmission control module nightmare. And it is a nightmare. Dealers typically won’t warrantee or allow return/refund on the vehicle computers unless they perform the diagnostics first. That’s a couple hundred bucks right there, before you get to buying the computer – which in my case for a 10 year old truck was $480, before sales tax. Then you have the labor to install it. Oh, and only the dealer can program it.   So I started snooping around on Google.  Using the search terms “remanufactured PCM” and “remanufactured …


Two Letters Re: Storing Spare Vehicle CPUs for EMP Preparedness

Sir: Most computerized gas engine vehicles built before 1996 (OBD-I) have a permanent computer memory module called a Mem-cal or PROM (programmed read-only memory) which can be stored indefinitely or used as-is from a parts house or junkyard. OBD-II vehicles, generally 1996 and later, all use the writable E-PROM which requires a specialized program and equipment to re-write. Also, the newer the OBD-II vehicle, the more computers it is likely to have. However only the module(s) for the power train are mission-critical. E-PROMs are more delicate than the older PROMs and sometimes require “re-flashing” to restore functionality. Obviously, the older …


Letter Re: Storing Spare Vehicle CPUs for EMP Preparedness

JWR,   Thanks for the great blog and everything you do for us.   I was at my local Ford dealer getting some work done and ask the service manager about computer modules for my 2006 F250 diesel. He told there are three different modules; engine, fuel and transmission. I ask how much they cost and he told me “a lot” but they are fairly simple to install, basically unplug the old and plug in the new one. What he told me next I hadn’t thought about and had not read; the computer modules must be programmed to work. Also …


The Golden Hours, by Brad H.

The three main factors in determining who lives and who dies WTSHTF are situational awareness, overcoming inertia, and dumb luck. The first two you have some control over. The third is always going to be beyond your control, except for Divine intervention, so don’t worry about it. If you are at mid-span on the Golden Gate Bridge when Al Qaeda sets off a nuke in San Francisco, or “The Big One” hits. In such cases, acceptance of God’s will is all you have to do to prepare. For those who are lucky enough to not be killed immediately when disaster …


Letter Re: Increasing Preparedness Planning Through the Rules of Three

JWR,   SAA Joe makes some good points in his article. He states however that “Hopefully 3 minutes without oxygen is self explanatory.  You have to breathe to survive!” then offers no solutions to a scenario where that may become a problem.   Scenario: You are stuck in traffic on the interstate due to an overturned tanker truck a few hundred feet in front Of you when a cloud of unidentified gas starts rolling towards your car from the overturned tanker. What do you do?   Scenario: You are at home which is located ¼ mile from a heavily used …


Letter Re: Low Cost EMP Protection for Electronic Gear

Jim, While working on my preps I found electrical specifications in the data sheet for the mylar-foil bags I was investigating for my food storage.  This reminded me that many computer components (e.g., motherboards, hard disk drives, and expansion cards) are packaged in mylar-foil bags for ESD protection.  I reasoned that since the ESD protection is provided by the conductive foil layer in the bag one should be able to use the same mylar-foil bags as Faraday cages to protect electronic devices and components from EMP. One of the perks of my engineering career at defense contractor is that I …


Letter Re: Mobile Fuel Storage System

James, Let me introduce your readers to propane and the many possibilities it offers your planning and TEOTWAWKI preps, that you will likely never have thought of before. Over the last number of years I have carefully thought out and planned a “system” if you will of key pieces of equipment which all operate on a single, inexpensive and highly efficient and large mobile fuel storage system. Naturally, I have the standard wood stove and gasoline operated family vehicle(s), but what is most interesting is some of the items I have been working on and extensively testing/ using on the side.   …
