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

I don't believe that for a moment.

Granite has sod-all radioactivity. Get a lump, try counting it - not
easy, even with good tools. The risk from granite is because it's found
in large underground masses and the daughter product is a gas. This can
travel, so if you have a house with a suitable basement and no
ventilation then you can be concentrating the radon from a huge quantity
of rock. If you live in a stone-built house on pillars though, no
hazard at all.
