Vacuum Tube Radios for Preppers

I often have SurvivalBlog readers write to ask me about vacuum tube technology and its robustness in EMP and CME events, and which antique multi-band vacuum tube radios to look for. I’m also asked how to determine which models can be run on both AC and DC power. To begin, vacuum tubes are inherently “hard” to EMP and CME but not invulnerable. They are also relatively safe from lightning strikes–but again not invulnerable. Modern integrated circuits are at the opposite end of the scale for vulnerability. In essence, the smaller gates in a microcircuit, the greater its vulnerability. In recent …


Letter Re: EMP Protection for Photovoltaics

Mr Rawles, I have been reading survivalblog.com for about eight months now and have been considering trying to go off the grid so to speak. I have been reading many, many very helpful and interesting articles about “how to” setup and or make your own solar panel system. There is one question that I hope that you can field to your contributors of this subject. How you you protect your solar panels and system from a HEMP should one occur? I have not found info on how to protect against this kind of attack. It does not seem practical if …


A Guide to Chemical Warfare Preparations, by Bryan R.

All survivalists, indeed all citizens everywhere, should give proper thought and consideration to the threat posed by Nuclear, Biological, Chemical (NBC) and Radiological agents, particularly chemical agents as they are the most likely to be encountered in dozens of possible situations. It is a fact of life that chemicals are everywhere, be they in surplus military storage depots, the local chemical plant down the road, the chemical laden train moving through the county, the semi hauling a tank filled with chemicals, or the nefarious terrorist who has finally realized that all he needed to make some very nasty blood agents …


Letter Re: The Disappearing Road Quandary

Mr. Rawles: I own a pretty densely-wooded 40 [acre property] in the Upper Peninsula (U.P.) [of Michigan]. The land on 2.5 sides of ours belongs to a timber company, and the land across the road belongs to the state. We live in a typical “stick built” house. It was built in the 1980s, with lots of big windows and two double-glazed sliding [glass] doors. We are four miles out of a town (about 2,000 population) but our house is only 60 feet from a somewhat heavily traveled county road. So our house is what you would probably call a tactical …


Letter Re: Warning of Massive Solar Flares?

Jim: After reading several articles on EMP in the form of a CME/solar flare, my understanding is that we would have hours or even days in which to prepare for such an event. Although I imagine that a massive CME would still cause damage to our electrical grid, I would also think that many homes could be disconnected from the grid and electrical equipment shielded in metal containers before the CME reached us. Any thoughts? JWR Replies: Yes, there will be 12+ hours of warning, but do not depend entirely on the mass media. At times, they seem clueless about space …


Three Related Disasters (Part 3), by Joe Refugee From Tokyo

After the first few days, it was possible to get some idea of what had happened. The initial numbers of fatalities had been fairly low, and it was hard to know how many had survived in the coastal towns. As the phone systems and many roads there were devastated, a big effort was going to be required just to scope out the damage. Sadly, it became clear that well over 10,000 lives were lost. In terms of life in Tokyo, though, it was electricity and basic supplies useful during disasters that became somewhat hard to come by. The other major …


Letter Re: Traces of Radioactive Iodine in the Milk Supply

Sir: It would appear that very low levels of radioiodine (I-131) have been detected in Western US milk, as could be expected. Presently, the contamination from Fukushima is taking over a week to cross the Pacific, and that time, combined with dilution effects, reduces the contamination from the Fukushima disaster to point far below the level of concern. At the present time. It also appears that the fukushima fallout plume is not rising high enough at present to become entrained in the jet stream However, reports from Fukushima, and analysis of the data available, indicates that a containment breach may …


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 …
