If this can detect background radiation, why does a customer say it can't detect radon radiation? Beta is beta. Anyone?

Radon gas mainly emits Alpha radiation. This one detects Beta, Gamma and X-Ray, not the Alpha. Only GMC-600+ detects Alpha radiation.

Is this device emp shielded? eg, can it still be used post a nuclear blast?

I don't know. I use it to measure radiation from rocks and orange fiesta wear dishes. If there is a nuclear blast your geiger counter will probably be melted and you will be vaporized.

Does this unit audibly click? I want a GC for field testing minerals so the tube must be near the side and otherwise suitable for prospecting.

Yes. The click sound is same as traditional Geiger Counter sound in movies.

Not on the 320E, If you menu dive on the GQ-GMC-500+, There is a setting that says it’s for food testing. Personally, I’ve not tested food with my 500+, though.
