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

. 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.
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

If he wants the spectrum he did get analyzed, I can get this done in several

Oh, so now you are a nuclear scientist. I'll have to change your moniker.

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
