“…The results of these studies are consistent with the results of this study, indicating that although the radon exhalation rates show large deviations between the respective construction materials, granites are more likely to show higher radon exhalation rates compared to marbles (Table 2). Granite contains a high value of radium since it contains feldspar minerals that can capture uranium from circulating solutions [38], therefore, it is considered that granite showed higher radon emission than marble in this study and previous studies. Furthermore, it suggests that indoor radon concentration could be significantly increased according to granites use [39] since granite acts as a major source of radon in a house depending on its characteristics when used for large-scale tiling in an enclosed space [40].…”

The objective of this study was to establish a test method for assessing radon exhalation rates from building materials considering radon related environmental policy and research in Korea. This method was established in consideration of cost-effectiveness based on the International Standards Organization (ISO) method and the closed chamber method, which is an evaluation method for the emission of hazardous chemical substances from building materials in Korea. The assessment of radon exhalation rates from five types each of granite and marble used in the construction industry in Korea gave mean radon exhalation rates of 0.497 ± 0.467 Bq/m2∙h from granite and 0.193 ± 0.113 Bq/m2∙h from marble, indicating higher radon exhalation rates from granite. These results are consistent with those of a previous study, indicating that granites are more likely to show higher radon exhalation rates than marbles.
