Every now and again, a group will come out with a report or a condemnation of the granite tile and counter top industry with regards to Radon gas release from the products. This happened again recently. This time, however, the reports were funded by a company that sells manufactured/synthetic counter tops.
My collegue Gratian Fernandes has addressed the situation in his Kitchen and Bath blog. His post is worth checking out for a more detailed discussion on the matter. You can see it HERE.
