Hi folks….

I’ve been doing a lot of scanning over the last many years, of a LOT of the huge library and collection of original government created civil defense, nuclear preparedness, nuclear war planning, and most specifically, nuclear fallout shelter documents I’ve amassed over the last 15 years.

I solved a mystery tonight, that had been vexing me for a couple of years.

The document named in the title above is probably the SINGLE best compendium of FALLOUT SHELTER RADIATION SHIELDING I have ever run across.

I’ve had the first 124 pages scanning in for almost three years, and had lost place of where I was.

In my move of my main computer system from a tiny desk in the corner of the bedroom, to a huge corner desk in the living room, I also brought out several of the boxes of prepping hardcopy in my collection. A small part of it consists of xerox copies of the originals that I had checked out from interlibrary loan, and couldn’t scan completely in time. My fix was to xerox what I didn’t scan, and set aside for future scanning.

In this repurposeing of my living room corner into a work area, I went through a LOT of material, added two new bookcases to the living room, and sorted out hundreds of books.

Amongst the misc. stuff….several xerox copies of things…some complete, others partial. The most vexing one was around 150 pages, that started with page “4-81″…and all throughout, no mention of the title of the source book.

Great stuff, including that most astounding piece of fallout shelter info I have found yet that I’ve never seen online…7 full pages of a TABLE OF MASS THICKNESSES…also known as appendix B of TR-20(Vol. 1).

Examples…Adobe 12″ thick gives a P.S.F (protection safety factor) of 116.
4″ common bricks PSF 40, Ceramic tiles PSF 3., 6″ Cinder Blocks PSF 30, etc, etc.

Very useful info.

So, in other words, *I FOUND THE MISSING HALF OF VOLUME 1*

My last big batch of scanning was in the 2nd full year (2004/2005) of my return to college life full time with my wife and kids. Well, all but my middle son have earned several degrees, and I’ve been able to bring some focus back into getting these docs put out to the masses, and finishing already started projects.

With all of the world seeming ready to fall apart at the seams (russian planes, stock woes, Iran borders, dogs and cats living together), I’ve had that little voice in the back of my head the past few weeks saying “finish your work…finish your work”.

A few of you that know me really well know that can mean a lot of things for me, but for this middle aged guy, finishing this scanning job and getting THIS manual online is that *one note * that rings true in my very near term responsibilities.

Here is the first 7 pages of the scan, and a shot of the cover.

and here is the pdf file of the Table of contents…

(166k in size and 7 pages long)

I’ll put many hours into it this weekend.

Something tells me this kind of info really needs to be available NOW.

Here’s the short version of different kinds of nuke bursts, blast waves, radiation and fallout, decay rates, values for dose and dose rate formulas, radiation effects on the body, barrier effectiveness vs. photon energy, mass thickness for different kinds of protection, and on and on.

This puppy is chock full of MATH, way over my head, has multitudes of charts for figuring out doses, effects, and such, and fallout shelter analysis of simple building to complex angular radiation paths.

There will be a few who really get the math part, and most folks should be able to get enough info to create safe fallout shelter spaces in whereever they plan to shelter…IF they need to shelter.

Here is a taste of the math part….

So, stay tuned. I also have vols. 2 and 5 scanned in already. No luck on 3 or 4. I’m still looking for those.

Comments welcome….
