"Over the past few years there has been some consumer
confusion about rumored radiation levels occurring in
natural granites used for residential countertops,
floors, tiles, etc. Unfortunately, the origin of these
concerns are advertisements and other communications
from the manufacturers of radon detection devices and
the producers of competing synthetic materials. Levels
of radiation from granite products, though technically
measurable, are in fact small fractional values of
established thresholds for environmental safety. The
truth of the matter is that granite is a safe product.
It’s been used for thousands of years and the
relationship between granite and radon has been studied
for years and years. How safe is granite? Numerous
independent, scientific studies have concluded that
granite countertops are safe. The Marble Institute of
America has produced this brochure to help you
understand granites, radioactivity and natural stone."
