Radon (222Rn) exhalation rates from granite countertops were measured using a continuous radon monitor. The countertops could be separated in three groups according to radon their exhalation rates. However, even for a worst-case scenario (e.g. E ~ 1.10 Bq m−2 h−1, no air circulation and full tile home) the contribution to indoor radon concentration is estimated to be [Rn] < 100 Bq m−3. In addition, despite the uneven radium distribution in the granite slabs, there is significant correlation (r 2 = 0.50) between the measured radon levels and the radium content of the granites.
