Dunno about the commercial state of the art, but I think both detection
problems should theoretically be within the ambit of classical
electromagnetism. Thus, you have backscatter from the materials at very
high frequencies, or alternatively resonance with their structure at the
lower ones. That's the passive detection part. If you have some active
control over the signals, you might try coherent detection in the
relevant band as well, but it sounds like that's out of your reach, and
it probably would be pretty cumbersome and slow in any case.

Abnormally high frequency xrays can do that. That'd pretty much be what
they use with the backscatter body scanners in airports that they're now
employing.

I'd go beyond dedicated TSCM, and into airline safety, because of the
above.
