'[OT] 11 Lost H-bombs'

"The U.S. military lost an estimated 11 nuclear bombs during the Cold War
that have never been recovered. Some of those incidents:"

I couldn't find a complete list:
- 2 in the Mediterranean Sea.
- 2 in the Atlantic Ocean.
- 1 in water 8,500 feet deep near Whidbey Island, Wash.
- 1 a few miles off the cost of Atlanta, perhaps near Tybee Island.

The military says that last one didn't have it's nuke core in it when it was
pickled off the bird back in '58... But they can't seem to account for the
core in their existing stocks... Hummm....

The concern isn't so much that it would explode, although the conventional
explosives in the bomb do become less stable over time, it is more likely
that the case will rust through and any core material will leech radiation
into the environment.

Louie Williford, 59, is nursing a beer at Doc's and not pondering the bomb.
"I don't really think about it," he says. "If it's gonna happen, it's gonna
happen. Ain't nothing I can do about it."

I wonder how many people own a Geiger-counter. I've only seen one in my
entire life. It was my dads, which I now have. But they are available.

http://www.imagesco.com/geiger/geiger-counter-kits.html $150.00. Probably
not worth it.

http://www.google.com/products?q=CDV-715+OR+V-777 or like that will show
lots of hits. Every so often someone lists one on ebay with a buy it now of
$20. For example:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230209033803

Nothing you can do about it?

On the other hand, I've been told there is enough uranium in my back yard to
make a bomb, if I dug it out a few feet deep and processed it to somehow
extract and refine it. And the background radiation is pretty constant. We
joke about testing toys from China.

Anyway: People worry about Nuke plants. How funny.

1.    Last first:

> Anyway: People worry about Nuke plants. How funny.

Straw man / substantially different comparisons being made
here.

2.    Geiger-Muller tubes generally have a finite lifetime.
Odds are your father's one is non functional and many
disposal ones may be too. Making one's own GM tubes from
scratch would not be too too hard. if you acquire a
commercial tube the rest is easy.

AFAIK there is one "buried in the soft soil of North
Carolina" which doesn't seem to match anything on that list.

They lost 2 in Spain in a single aerial incident with,
AFAIR,  one being recovered from a vast depth at sea with
great effort and the other being spread in very small pieces
over a very wide area of countryside.

They may or may not or may or may not or ... have lost one
in a fire at Greenham common when a ?B52? jettisoned drop
tanks during a gone-badly-wrong takeoff and tghe resulting
fire toasted an adjacent nuclear bomber. There was much
niether confirm nor denying over this for many years.

They didn't lose one at McMurdo in the antarctic - that was
just the friendly local reactor having issues and spreading
its joy a little too far and wide for total comfort. They
shovelled up an extremely large amount of soil and other
stuff and flew it no expenses spared back to the US where no
doubt it still resides in some safe-forever NIMBY
repository.

I do :-)
It's probably as functional as your father's one at present.

Amount varies with area.
A very small percent goes a long way in a deep yard sized
hole.
Depending  on local geology you may get almost none or
several kg from a deep enough hole over your whole section
BUT extracting it from that much soil would be about as easy
as getting it out of seawater AND it would be very mainly
U238 with minimal U235. Getting the 235 from the 238
requires conceptually simple but in practice expensive and
difficult machinery (differential gas diffusion and/or
centrifuge). Real people, some of whom live in several
countries (3 come to mind immediately) with names beginning
with I,  have large numbers of such. It is likely to be
noticed if you get some.

If you want to up the raw amount of U23x in your source ore,
failing being able to acquire a yellow-cake facility, you
could start looking at old gold dredge tailings, depending
on area.

Could build a KFM- simple nuclear-physics-based short-term integrating
dosimeter.

http://en.wikipedia.org/wiki/Kearny_Fallout_Meter

Probably the cheapest and easiest method for detecting radiation.  Not
very useful at low rates, and since it is integrating, worthless for observing
brief spikes.  Also depends on a solid surface, so you won't be wandering
the woods looking for a lost nuke with it.

Still, it's a marvel of a simple demonstration of nuclear physics.

I learned about those in "Pulling Through" by Dean Ing.
Fun novel which is also a survival guide.
Need to know how to build a fallout shelter that will seal out the
finest junk?  Read the book.
Shelter management?  Read the book..  :)

Going to take a trip down to Westland, Russell? ;)

I have the relevant geological maps, with concentrations per
ton plotted :-).

I reckon buying an old dredge and a tailings heap is liable
to cost very little.

And, one may get some gold along the way :-)

For substantial details on building your H bomb read Tom
Clancy. ?Sum of all fears?

Knowing Russell's interest in clean cheap energy sources for the poor and
needy, it's more likely that he is getting ready to go "nuclear boy scout"
and build a power plant rather than an H-bomb.

fffffttt, what a fuss. It's not like they're short of them. Like parents
who fret when a kid swallows a coin. Cheapskates
