Here is my latest best effort with trinitite using Am241 as an exciter.

Only 3 elements really stand out: Fe U Ba.? There are other possibilities such as Sn and Cs but I can't say for sure without a much longer run.? Note that many of the peaks are to be ignored because they come from the Am241 and the Pb shield.

Charles- Great set of scans of Trinitite XRF! Thanks.? A favor? No rush and only if/when you can. Please rerun same test, same conditions, time,? and sample, but this time no exciter? Let's explore excited U L X-Rays? vs. those from Pu-239 decay. Geo

Now a try-and-fail for Sr-90 in Trinitite. First the decay scheme of Sr-90:  Next the % of Sr-90 left and the determination of Sr-90 to stable Zr-90 atoms which must be present:  Only 16.27% Sr-90 left after ~2.5 T/2. Lots more Zr-90 atoms than Sr-90 atoms then. Using the ICP-Mass Spectrometer from the YouTube video: we compare Zr-isotopes detected against natural abundance of Zr in earth's crust by calculated %:  Conclusion- ICP-Mass Spectrometry results show no Sr-90 and the indicated Zr abundance does not show in increase over natural abundance. Conclusions: A) Sr-90 presence is below ICP-Mass Spectrometry? threshold of identification. B) Zr-90 natural abundance overwhelms any atoms contributed by Sr-90 decay Result = Fail ? Next approach will be direct detection of Sr-90/Y-90 Beta Particles and segregation from Cs-137/Ba-137m Beta Particles by filtering and magnetic methods, from my article "Detecting Sr-90 Betas in the presence of Cs-137" Geo

While we're still thinking about Steve's metal fragment, here is a scan I did comparing it to one of my own. The filled red scam is Steve's, the black outline scan is the Blob. Inclusions are quite similar, but the amplitude is bifferent.

Hi Dave. Join the conversation- If you haven't already, download the free? DPPMCA program from AMptek, load it then you can download the .mca files we send.

OK, guys, what do I have to do to get into this high-res XRF world?? I've got the Am-241.? How much and where for the good detector? And what dies it take?? It's only a 'maybe' in considering the slim check book.

I agree. There's a lot of iron there, very little else, 1930's tech "steel". These were not atomized, but fragmented from a structural section, probably very near to the gadget, like the tower. Just a guess.
