Letter Re: More About Understanding EMP and HEMP

JWR: Your discussion about EMP effects from ground blast or a low altitude nuclear explosion [posted on April 23rd] was excellent. Apart from electromagnetic coupling to conductors, which would extend the destructive horizon, atmospheric nuclear explosion EMP effects are limited in range. This is due to several factors, first by the rapid absorption of gamma rays by molecules in the atmosphere (small absorption layer or boundary effect), and second by the line of sight radiation from the decay of the short lived Compton electrons (limited horizon effect). You correctly discount the likelihood of a high altitude EMP (HEMP) as an …




Letter Re: Question on LEDs and EMP

Hi Jim: Your blog is the best I’ve come across on the Internet. Very useful information. Regarding the subject of [Electromagnetic Pulse] EMP, are the new Light Emitting Diode (LED) flashlights more, or less immune to EMP than those using conventional incandescent bulbs? Modern solid-state circuitry is in grave danger of terminal damage in the event of an EMP occurrence. LEDs are composed of a semiconductor junction, similar to transistors and integrated circuits. Do modern LED flashlights have enough of the right characteristics to pick up sufficient EMP burst energy and become permanently useless? Your comments please, and thank you. …




Letter Re: Advice on Where to Learn Practical, Tactical Skills

Dear Jim: As my confidence in the dollar depreciates and my desire for skills increases, I’m wanting to convert FRNs into hands-on knowledge. What weeknight or weekend workshops would you recommend? Are there any places where you can learn Army Ranger skills without joining the military? Animal husbandry, and so on? – Spencer JWR Replies: There is a tremendous wealth of free or low-cost classes available–enough to keep you busy every weekend of the year if you are willing to drive a distance. If you have time and just a bit of money, you can get some very well-rounded training …




Letter Re: Advice on EMP Protection for Electronic Gun Vault Locks

Jim: I haven’t noticed this discussed on your blog, or any other for that matter. Is there anyway to protect a gun safe that uses the electronic key pad instead of the standard dial combination lock from electromagnetic pulse (EMP)? I wasn’t thinking along those lines when I purchased it several years ago. I enjoyed “Patriots” immensely and will be re-reading it soon. Thanks for the terrific blog. – Bruce H. JWR Replies: I mentioned this about a year ago in SurvivalBlog, but it is worth repeating: A steel gun vault body itself makes a decent Faraday cage. (Although a …




Nuclear, Chemical or Biological Disaster Preparedness, by Brian A.

One of the recent phrases the media has used almost to exhaustion is, “dirty” bomb. A dirty bomb, or radiological dispersion device (RDD) is basically an explosive device with some element of radioactivity attached, or some other means of distributing radioactive particulate matter. When detonated, it releases radiation in the form of dust or debris, which is harmful mostly when inhaled, or introduced into the body by other means, (eyes, open cuts, etc.). The main terror use of such a weapon would be to contaminate emergency services workers responding to the initial blast. In the 1990s, Chechen rebels reportedly placed …




Letter Re: Retreats in the Eastern United States

Dear Editor: As you likely know from my prior communications, I am a long time reader of your web site, your novel “Patriots”, and your recent “Rawles on Retreats and Relocation” book, which is, other things being equal, well written and interesting. However, the obvious exclusion, which you freely articulate, is the Eastern US. I’ m bringing this up for two reasons: 1) I am an ex-military Emergency Room Physician, who is convinced that TEOTWAWKI is very, very near ( the next signal is when the US Dollar Index goes below 77, that’s it! The “Patriots” [economic collapse] model will …




Letter Re: Practical Information on EMP Protection for Home Electronics

Sir: Thank you for your hard work. I am not sure if this was covered here before and, in the case it has not, I wanted to supply the following information to help suppress fear regarding electromagnetic pulse (EMP) and specifically, its effects on communications equipment. I am tired of reading “seal the radio in a metal ammo can, place the ammo can in an old microwave and place the old microwave in an old refrigerator, which is then buried under 8 feet of earth,” et cetera. Here is the reference for a four-part article in Amateur Radio Relay League …




Letter Re: The Jericho Television Series — A Review

Dear Jericho Staff, So I’ve read others comments online about the TV show Jericho. I decided to watch it via the CBS.com web site and see if there was more value than my initial dismissal from the original pilot. My feelings are On the one hand, it’s nice that someone had the guts to put a survival drama TV show on the air, in prime time, and have the guts to tell the more palatable survival-apocalyptic stories set here in the USA. Points for that. Each episode talks about a couple different survival problems. Each deals with a few new …




Two Letters Re: The Jericho Television Series Returns With New Episodes

Hi Jim: Hit the nail on the head didn’t you? Jericho is nothing more than the standard protagonist/antagonist Hollywood pipe dream of heroes coming out of the woodwork to save the day. I certainly hope no one is seriously considering this show as a realistic depiction of life after “the pulse”. Rather, I compare this show to the “Dark Angel ” series, i.e. for network TV, fairly good science fiction with almost nothing based in fact. Actually, I retract that statement. As far as depicting the scenario after an EMP event; the “Dark Angel” series was quite a bit more …




The Jericho Television Series Returns With New Episodes

Airing of new episodes of the television series Jericho will resume on February 21st here in the States. (After some sort of “split season” break.) I’ve watched most of the episodes via the Internet, since we don’t own a television here at the Rawles Ranch. Here is my “$.02 worth” evaluation of the show, based on my own viewing and from comments that I’ve distilled from Internet discussion boards: Jericho severely stretches credulity for accurate portrayal of a post-nuclear America. Apparently all of the female characters must have been secret adherents of the Maybelline School of Survivalism and hence stocked …




Letter Re: Questions on Multipurpose Home Shelters

Sir: I live in Georgia and we have more than our share of tornados. We usually go to the basement to my office during storms but I’ve decided that even though it’s underground on 3 sides, with only 3/4 plywood and sheet rock between us and the garage doors that it is no longer a viable option. I’ve looked at FEMA plans and I’ve scratched my head and come up with this idea but wanted to kind of say it out loud to someone to see if it sounds too crazy. The back part of the basement is almost completely …




Letter Re: Junk Shop Survival Tools

James, I read Nuclear War Survival Skills [by Cresson Kearney) several years back and have read and re-read the book on a regular basis. In fact, along with your novel “Patriots” (acquired 5 months back) I have loaned out and gifted copies of each to family. All were ‘struck’. After realizing the need for expedient and planned shelter, but lacking the real buying power that I desired, I set about securing many of the hand tools that I had previously overlooked, i.e. tools that were essential according to Cresson: Picks, Shovels, etc. Lowes and other stores didn’t stock old world …




Letter Re: New York Military Bunker on eBay

Hi Jim, I can’t say I see many bunkers for sale on eBay. I personally don’t consider New York state ideal for a retreat location, but it is interesting to see this property available nonetheless. I’d be a little concerned about potential HAZMAT issues. BTW – I’m really enjoy reading Rawles on Retreats and Relocation. I’m in between “permanent” dwellings at the moment and it helps to have such a resource when considering my options. Kind Regards, – M. Artixerxes




Two Letters Re: Israeli Nuclear Saber Rattling

James The Olmert government would not do a nuclear strike of any kind even if we were at risk of being completely overrun. The weakness in response can be seen in the war in Lebanon where only minimal measures were used and only against safe targets after about 8 hours of leaflet warnings. Olmert simply will not upset his liberal European friends even when Washington orders him to act strongly. This is likely part of a wind up similar to what we saw before the Iraq invasion although I am doubtful that there will be an American ground occupation of …




Ten Things That Will Get You Killed While Bugging In, by Paul C.

“Bugging in” is the term used for staying at home while waiting for an event to pass you by. [As opposed to “bugging out”–fleeing to a lightly populated region.] Even the largest civil events of the last one hundred years haven’t set society off here in the United States of its normal course for more than two weeks. Double that for a month and you’ll survive, or out survive, any event likely to hit. After whatever event that has set society on its end has struck the 99 out of one hundred people that haven’t prepared for survival are going …
