Cooper was involved in electronics..

My buddy who I've known since the 70's is a electronics nut...he told me last year to look into the medical field when I showed him the elements...the radioactive ones alerted his reason..

specialized stuff like Radar systems..

Given the high number of Ti particles, I'm really thinking it can be from dirt/soil. How did Tom decide this wasn't some Ti oxide?
Soil can be high in Ti

I think all those elements are found in dirt too.

Whoa, welcome back, E Vick. Long time, no see.

There are a number of good reports.
I'm going from this one currently

page 9 is instructive if you've never seen this kind of analysis before (attached)

Abstract
Samples of soils or other regoliths, taken at a depth of approximately 20 cm from locations about 80 km apart throughout the conterminous United States, were analyzed for their content of elements. In this manner, 1,318 sampling sites were chosen, and the results of the sample analyses for 50 elements were plotted on maps. The arithmetic and geometric mean, the geometric deviation, and a histogram showing frequencies of analytical values are given for 47 elements.

The lower concentrations of some elements (notably, aluminum, barium, calcium, magnesium, potassium, sodium, and strontium) in most samples of surficial materials from the Eastern United States, and the greater abundance of heavy metals in the same materials of the Western United States, indicates a regional geochemical pattern of the largest scale. The low concentrations of many elements in soils characterize the Atlantic Coastal Plain. Soils of the Pacific Northwest generally have high concentrations of aluminum, cobalt, iron, scandium, and vanadium, but are low in boron. Soils of the Rocky Mountain region tend to have high concentrations of copper, lead, and zinc. High mercury concentrations in surficial materials are characteristic of Gulf Coast sampling sites and the Atlantic coast sites of Connecticut, Massachuetts, and Maine. At the State level, Florida has the most striking geochemical pattern by having soils that are low in the concentrations of most elements considered in this study. Some smaller patterns of element abundance can be noted, but the degree of confidence in the validity of these patterns decreases as the patterns become less extensive.

I agree that the stainless steel particles are not "from nature"

But 377 could be right..those could have come from Hayden's parachute. Or maybe a more typical machine shop/foundry in that era...just steel and aluminum. Not titanium.
And no rare earths.

They found Ti at pretty much all of the sample sites they used in the US. map attached from page 52 of the report.
Varying amounts. Darker means more.

They have separate maps in the report for each element. Some elements weren't as uniformly distributed as this one.

from that paper, on the behavior of titanium at room temperature, with air.

When the titanium is exposed to ambient air at room temperature, a passive oxide film is spontaneously formed on its surface. This passive film is amorphous, very thin (5-10 nm thickness [9]), and composed of three layers [10, 11]: the first layer adjacent to metallic titanium is TiO, the intermediary layer is Ti2O3, and the third layer, which is in contact with the environment, is anatase TiO2. At room temperature, anatase TiO2 is the most important layer in thickness and responsible for the integration between the implant and the human bone when the material is not submitted to a thermal treatment at high temperature. The surface oxide film on titanium formed in the air is so protective that the further oxidation of titanium is prevented in various circumstances and mediums [12]. Even during sterilization in autoclave under a saturated water vapor pressure at 120 _C for 1.8 ks, oxidation of titanium does not proceed [12].

the cuttings were smaller total particle counts? not sure

In any case, yes those are separate.

Just because you find Al and SS cuttings, doesn't mean everything else is also from human manufacturing.

That's what I'm saying. There's this assumption of single donor site for all the materials. That seems crazy to me. And assuming they are all human-manufactured or something.

I can't imagine how Tom Kaye justifies this. Unless he has more data we've not seen

For instance, no data has been released about Yttrium. I assume it's just trace..hardly any?
