Letter Re: Question on generators and EMP

HJL, We have been considering having a whole house generator installed at our house, since we occasionally lose power in our neighborhood for days at a time. Additionally, the threat of an EMP pulse damaging the grid and our being without power for a lengthy period of time is an even greater concern. My question is: is a whole house natural gas powered generator, like a Generac 22kv unit (along with the associated auto switching panel), susceptible to EMP? If so, what would be the best way to protect it? When I ask the electrical contractors bidding on the job, …


Letter Re: EMP-Hardened Ham Radio Communications, by PrepperDoc

Being a prepper and a Ham I found the article “EMP-Hardened Ham Radio Communications” by PrepperDoc very interesting but also somewhat over my head with regard to tubes and the like, so I put it out to more experienced members of our ARC (amateur radio club) for comment. The response from one Ham is not a slam but rather additional information for the like-minded. “There was no mention of electrolytic caps and the frequent need to replace them when using older gear. Also, tube rigs are power hogs; where are you going to get the power? Alternate power sources (inverter …


EMP-Hardened Ham Radio Communications, by PrepperDoc

3

EMP attack is often considered the most rigorous of survivalist situations, due to the likely complete loss of electrical grid, many vehicles, and many transistorized/computerized products. Our group worked to provide post-EMP communications that would allow effective communications post-event. We had two major requirements: Short Range Communications. Two, separate, defense-hardened homes that were approximately 30 miles apart had to be able to communicate across a medium-sized city, and Long Range Communications. Both homes had to be able to receive news from in-state and out-of-state sources. These were considered necessary to receive adequate advance warning of defense issues, such as advancing …


What Can We Expect and Do Now To Prevent a Nuclear Power Plant Meltdown in an EMP Scenario, by B.Z.

I was prompted to write in response to the reader who commented on the recent article entitled “Six Common Misconceptions About EMP”, by G.P., which was published in December 2014. The reader asked specifically: “Can we expect the 100+ nuclear power plants in the country to have meltdowns when the grid can no longer supply the power these plants need? In particular, what about the spent fuel pools?” Let me first say that I personally have met the author of this article, and I can attest that he is one of the foremost experts on EMP in the world. My …


The Good News About Nuclear Destruction, by S.C.

What possible “good news” could there ever be about nuclear destruction coming to America, whether in the form of dirty bombs, terrorist nukes, or ICBM’s from afar? In a word, they are all survivable, at least for the vast majority of American families, IF they know what to do beforehand and have made even the most modest of preparations. Tragically, though, most Americans today won’t give much credence to this good news, much less seek out such vital life-saving instruction, as they have been jaded by our culture’s pervasive myths of nuclear un-survivability. Most people think that if nukes go …


Scot’s Product Review: MobileSec Cellphone Blocker and Laptop EMP Shielding

I always liked the line that states, “Just because you’re paranoid, doesn’t mean that someone isn’t out to get you.” These days, in addition to physically trying to “get” you, there are also those who are trying to virtually get you by stealing your information for misuse. There are those who might want to wipe out everything with an EMP event so that not only do you not get to use your own stuff, you can’t even get a backup from someone else. It could be a foreign government, a criminal consortium, or even your own government doing the deed. …


Letter Re: What Haven’t I Thought Of For Nuclear Survival?

Hugh, I spent 15 years in the nuclear industry working at a nuke plant and was the site Radiochemist most of that time. I have never seen any sort of functional anti-C that will “stop” or even attenuate gamma radiation. In fact, nothing will “stop” gamma rays. Shielding (lead, concrete, water) can attenuate gamma rays, but it will not “stop” it. Some measurable energy still gets through all shielding. So I am not sure what the author is referring to, but any anti-C that isn’t meant to be disposed of has to be deconned after each use. Of course when …


What Haven’t I Thought Of For Nuclear Survival?, by D.K.

It’s easy to prepare for a specific disaster and then forget about it. Whether it’s an economic collapse, power grid failure, or nuclear attack, gathering supplies just isn’t enough. There are a spiderweb of choices to be made after each event, and this article will focus on options you may not have thought of yet, if a nuclear strike were to happen. Aside from knowing the foundations to nuclear survival, there are other important topics, such as owning protective suits, location decisions, and community goals. As with most survival situations, nuclear survival is a system of Q/A– questions and action. …


Letter Re: Six Common Misconceptions About EMP

A question for the writer of the EMP article. Though the article was informative, he, like pretty much everyone else that writes about EMP’s or other forms of grid failure, completely ignores the 900 # gorilla in the room. Can we expect the 100+ nuclear power plants in the country to have meltdowns when the grid can no longer supply the power these plants need? In particular, what about the spent fuel pools? My understanding is that they have emergency generators and anywhere from a few days to a few weeks worth of fuel on hand but even if somehow …


Guest Article: Six Common Misconceptions About EMP, by G.B., PhD

Many misconceptions about electromagnetic pulse (EMP) effects have circulated for years among technical and policy experts, in press reports, on preparedness websites, and even in technical journals. Because many aspects of EMP-generation physics and its effects are obscure, misconceptions from those who do not perceive the seriousness of the effects to those who predict a doomsday chain of events are inevitable. However, not all EMPs are the same, with the most significant effects being caused by E1 and E3 fields. Nuclear bursts detonated at altitudes above 40 km generate two principle types of EMPs that can debilitate critical infrastructure systems …


Identifying and Protecting Yourself and Your Family Against Hazardous Chemical Materials Incidents, by a Marine in Missouri – Part 2

There are many different levels of protection out there. Military gear is specifically designed for CWAs. There are three general levels of protective equipment– level A, level B, and level C. Military gear is somewhere in between level B and C because it is designed for specific chemicals. Level A gear is fully encapsulated, typically a chemical-resistant plastic suit with a Self Contained Breathing Apparatus (SCBA) or provided air through a pressurized air system and a hose. This provides both splash and total vapor protection. However, the downfalls to this nearly complete protection are: It is cumbersome to wear, Depending …


Identifying and Protecting Yourself and Your Family Against Hazardous Chemical Material Incidents, by a Marine in Missouri – Part 1

We live in a society that depends on hazardous materials to create the technological wonders and comforts we expect for everyday life. Whether you take your kids to a swimming pool or drink any sort of city water, you knowingly or unknowingly depend on large amounts of chlorine to ensure the water is safe. Anywhere there is a mechanic shop there are chemicals required to lubricate, clean, and repair materials; some of those chemicals are potentially dangerous or deadly. As you drive down the highway you see thousands of semi-trucks carting loads of materials that could be more deadly than …


Letter Re: EMP

I currently keep my backup mini-iPad in an EMP bag. Do I also need to keep my power supply for it there, too? Thanks – A.B. HJL replies: Yes. In fact, it is probably more important that the charger is in the bag than the ipad. Being an electrical engineer with considerable radio technology experience, I have a perspective that is a bit different than most on the subject. The true danger of EMP is in having antennas or things that act like antennas pick up the electrical energy. If the object in question either has wires or parts that …


Potential Bioterrorism Agent Found in Colorado, by Cynthia J. Koelker, MD

July 2014: One of the deadliest diseases on earth is right here in our own back yard, so to speak…with no vaccine, fatal without antibiotics, and on the CDC’s “Category A List” of potential bioterrorism agents. Don’t panic just yet. The disease also occurs naturally, as is the case in this month’s outbreak. However, overnight I’ve changed my outlook on the disease. What I’ve recently described to my students as highly unlikely is instead alive and well on the prairie. I’ve gone from believing I’d never encounter this infection to thinking it’s entirely possible. The next time I see a …


Letter Re: EMP

Hugh, While the routers and switches do require power (which will be spotty at best), they too will be fried by the EMP. Many of the modern ASICs are based on IBM proprietary copper chips and as a result really don’t get along well with any form of EMP. It’s bad enough that I’ve seen a floating ground stretched between two buildings fry Cisco, ACC / Wellfleet, and Extreme gear. The only purpose-built router that is tempest hardened is the very old TGS router by Cisco. This was an AGS that was built into a hardened shell. Wide scale deployment …
