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. Scottish granite is known to be. One of the
most radioactive buildings in all of Britain is the Marischal College
at University of Aberdeen ( second or third largest granite building
on the planet). As I recall G.P. Thompson (JJ Thompson's son) did
some of the early quantum mechanical experiements on electrons there.

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?
