The main railway station in Edinburgh (that's in Scotland), Waverley
Station, is built into solid granite. I was told once that if a nuclear
plant had the same ambient radioactivity (or whatever they call it) the
plant would be evacuated and shut down for a very loooong time :-)

Granite is, apparently, a naturally radioactive mineral.

Not all granite is hot.

Yes.

All granite is radioactive.

The activity varies, a lot. Most granites are somewhat hotter than
most sedimentary stone, but the sedimentary stone at the Okla
mine is probably hotter than any granite.

...

And back to the original topic: which is more carcinogenic -- the
radon coming out of granite or the nasty chemical binders in solid
surface or quartz chip like silestone?


It depends of course.

It's the dose that makes a poison.
