Re: [Vo]:Celani's report on Rossi January 14 test
Jed, If he did a spectrum measurement for a few minutes, he should have a decent sampling. This depends on the detector, of course, but all handhelds that I've dealt with (which is a limited sample) are designed for rapid detection/spectra collection. NaI isn't the best detector material, but it should be adequate. Usually the detector stores the last spectrum collected. If he wants the spectrum he did get analyzed, I can get this done in several different ways. Chances are the secret may not be a gamma emitter at all, but it's worth a go. Is there any chance he a) still has the spectrum he did collect, and b) would be willing to share it?

From: albedo5 . Chances are the secret may not be a gamma emitter at all, but it's worth a go. With a lead-shielded reactor it is doubtful that any radiation other than gammas could be detected.
RE: [Vo]:Celani's report on Rossi January 14 test
Well, neutrons may be out, since the patent mentions lots of boron and few neuts would escape anyway, and there are almost no secondaries from the boron ash: lithium and alpha (as we know from BNCT). Celani's comment are indeed a bit puzzling, given the shielding - and the already admitted failure to see anything at 511 keV. That makes a lot of sense. . however . I have suggested in a previous post that Rossi - like BLP, could be using sodium hydride as the (spillover) catalyst, giving him a strong reason to hide this (Mills' IP portfolio). Yikes! it is a very strong reason, come to think of it. If so, and if there are energetic protons, then the Na(p,gamma) reaction is the culprit. Especially since this one is very important in cosmology, thus well studied, and with a characteristic 1.275 MeV signature. Aha. This little detail does make NaH an even better candidate. Jones From: albedo5 You could probably see neutrons, if any were emitted - if the detector has a neutron capability, of course. Even if you see them, you now know a neutron emitter is present, nothing else. So the chances of seeing anything useful other than high-energy gammas is really pretty low. The algorithms that identify components within a spectrum are rather sophisticated, though. Hope springs eternalas always. . Chances are the secret may not be a gamma emitter at all, but it's worth a go. With a lead-shielded reactor it is doubtful that any radiation other than gammas could be detected.

Re: [Vo]:Celani's report on Rossi January 14 test
It seems I spend most of my waking hours lately analysing spectra, with handheld detector characterisation a close second. It's a good thing I have such great toys to do it with. I recently dreamed about daughter isotopes prancing around a lovely neutron waterfall, with Bremsstrahlung providing the background music. Now THAT is scary. Interestingly enough, one of the detector materials I've had to delve into lately is NaI. I suspect I have the detector definition used in at least one application, so if there's anything to be found, I can dig it out (with some serious help). I'm writing a white paper right now describing a numerical method I created to match detector resolution parameters with Gaussian broadening parameters, with NaI being one of the materials. It keeps me off the streets, and it also pays well. :) I'd love to finally contribute something here!
