Dear Elton, Lists;
Very interesting reading. I would presume (well actually know) that
any of us that have specimens of petrified wood from Utah (especially
the Henry Mtns/southern deserts), Wyoming (definitely Shirley Basin, Gas
Hill for sure)...........Or anyone with dinosaur bone from Colorado,
Utah, Arizona, have more radiation around than they would ever believe.
If anyone ever gets a chance to hunt meteorites around Hanksville Utah,
the radioactive soils and petrified woods are rich in yellow radioactive
mineralizations...and they are "down winders"...the incidence of cancers
and liver damage is phenomenal. Many of the old timers love to talk
about who died and who has what.
Sunny, calm, 40 degrees, NO SNOW
Radon Dave F.
PS, Nininger memorabilia is at 97 visits, four bids now _at_ $34.33 and
five days, seven hours left...Please help support IMCA with a big 'OL
BID. 100% of bid price will go to the IMCA web site, and..FREE
S&H...'cause we love you!

I have some samples from both Hiroshima and Nagasaki which aren't as good. Interesting thing with these ceramics, is the heat reached sufficient high temps long enough for creamic/clay(refractory) roof tiles to form a glass fusion coating. Some roof tiles became so plastic they flowed together into blobs! I consider this a very remarkable feat given the melting temperatures of clay. Even river pebbles ( in the pyroxene class) formed glass blobs on their exposed surface. Some blebs of glass very similar to Trinitie can be found in soil and sand. I assume this fusion coating is what brought this to the Meteorite category in the sense that it is a natural glass(sic). A question is was the glass formed from micro mineral particles or, did biological coatings contribure to a natural
"glaze"? For the artsie types out there you know how hot you have to fire ceramics in the Kiln. To me it looks like both may have happened but the bulk was from the tile itself As to radiation and radioactivity and half lives, etc.-- the radiation at all 3 of the 1945 blast sites are back to a level which is described as slightly above background. The half lives of most the contaminants have dropped radiation to well below safe levels. The remaining ionizing radiation today is mostly alpha and rarely do they find any plutonium particles at Trinity, based on my recall of studies over the years at these sites. So while I don't have the specifics of what daughter products were produced, I remember the findings and those are that radiation levels are largely normal and passed being harmful decades ago.
