As the popularity of granite countertops has grown in the last decade — demand for them has increased tenfold, according to the Marble Institute of America, a trade group representing granite fabricators — so have the types of granite available. For example, one source, Graniteland (graniteland.com) offers more than 900 kinds of granite from 63 countries. And with increased sales volume and variety, there have been more reports of “hot” or potentially hazardous countertops, particularly among the more exotic and striated varieties from Brazil and Namibia.
“It’s not that all granite is dangerous,” said Stanley Liebert, the quality assurance director at CMT Laboratories in Clifton Park, N.Y., who took radiation measurements at Dr. Sugarman’s house. “But I’ve seen a few that might heat up your Cheerios a little.”
Allegations that granite countertops may emit dangerous levels of radon and radiation have been raised periodically over the past decade, mostly by makers and distributors of competing countertop materials. The Marble Institute of America has said such claims are “ludicrous” because although granite is known to contain uranium and other radioactive materials like thorium and potassium, the amounts in countertops are not enough to pose a health threat.
Indeed, health physicists and radiation experts agree that most granite countertops emit radiation and radon at extremely low levels. They say these emissions are insignificant compared with so-called background radiation that is constantly raining down from outer space or seeping up from the earth’s crust, not to mention emanating from manmade sources like X-rays, luminous watches and smoke detectors.
for a butcher block i highly recommend the ones that have the cutout which will fit a plastic, or marble cutting and working surface. wood, beautiful and easy on knife edges tends to absorb and collect nasty bits. with the newer ones all you need to do for cleanup is remove the plastic surface and stick it in the dishwasher. for pastry or for working chocolate the marble is surface of choice because it runs about 3 degrees below the ambient temp of the room. it can then be washed with soap and soft cloth, disinfected and sheen restored with neatsfoot oil.

p.s. in my experience granite looks great, works shitty. and for me, it's all about the work.
