    Even today, an XRF spectrometer isn't quite so user-friendly that a casual inexperienced user can just walk up to one and start using it, without training. Back in the 1960s, XRF was still cutting-edge technology, so would have been even more necessary to have a trained technician do the operating.

    Of course, these days, we have portable hand-held XRF analysers, so you no longer need to send the coin to the lab - you can bring the lab to you.

    Waste no more time arguing what a good man should be. Be one.

    Has detailed XRF analysis been performed on the Fugio material with new equipment? I would think it has, but do not recall seeing a detailed analysis presented. Cheers, RickO

    Is XRF similar to SEM-EDX? We used SEM-EDX (Scanning Electron Microscopy with Energy Dispersive X-ray) on magnetic chip detectors along Spectrometric Oil Analysis when I was active duty on jet engines for wear metal content. We had some pretty cool tools. On the other side of the house was the x-ray vault.

    They are similar techniques to determine the elemental composition. I believe XRF will detect to smaller amounts with lab equipment. Don't think the hand held device is that sensitive.
