I'll also note that granite is radioactive yet we build buildings
with it without concern.

It's detectable, but that doesn't mean that it's a problem.

Actually, it is! As I recall, removed granite waste is a low-level
radiation "hazard".

Banannas will also kick off geiger counters, I guess they are too commonly
used by the public to be classed though.
