Results are presented from approximately 9000 Rn measurements made in New York state, North Carolina, and South Carolina. The estimated statewide geometric mean concentrations were 28.1 Bq m-3 and 55.8 Bq m-3 for basements in New York state, 27.5 Bq m-3 for living rooms and 108.9 Bq m-3 for basements in North Carolina, and 25.0 Bq m-3 for living rooms in South Carolina.
研究结果来自于在纽约州、北卡罗来纳州和南卡罗来纳州所进行的约9000次氡测量。纽约州地下室的全州估计几何平均浓度为28.1贝可勒尔每立方米和55.8贝可勒尔每立方米,北卡罗来纳州客厅为27.5贝可勒尔每立方米,地下室为108.9贝可勒尔每立方米,南卡罗来纳州客厅为25.0贝可勒尔每立方米。
