I came across this article today, though had seen similar mentions in the last few days. Granite countertops have been detected as having high levels of radon — enough to potentially contaminate the air quality of your home. A home radon detection kit may help you determine if your family is at risk. I am also very glad I did not go for granite in my kitchen!
So what types of counter tops are safe? Many formica countertops have a laminate over particle board and particle board is known to emit gases like formaldahyde. So that’s not great news either.
A friend of mine poured concrete countertops — durable, modern and non-toxic. They loved them.
There are several other eco-friendly options here including recycled glass, end-grain bamboo, recycled paper, sustainable wood, and recycled aluminum. Personally, I would avoid the aluminum as it has its own issues (ie, may be linked to Alzhiemer’s).
Other options are Enviroglas, Lithistone, Syndecrete and IceStone.
