A commercially available activated charcoal detector for measuring Rn activity concentrations in air was calibrated with known amounts of Rn and examined in terms of air luminescence counts and interferences from Rn and Rn . The results for conditions normally encountered indoor indicate that the detector is simple and reliable. The method has been applied to assay indoor Rn activity concentrations in 387 homes in Tokyo and the adjacent four prefectures, which ranged from 0.7 to 140 Bq/m and averaged 22.7 Bq/m. |
