| Özet |
| The specific activity of 226Ra, 232Th and 40K in 52 Turkish pumice samples collected from 11 geographical areas located in Central Anatolia, Eastern Anatolia, Mediterranean and Aegean regions was determined by gamma-ray spectrometry with a high-purity germanium (HPGe) detector. The specific activity of 226Ra, 232Th and 40K ranged from 12.7±0.5 to 256.2±9.1Bqkg−1 with a mean of 89.1±65.2Bqkg−1, 12.3±1.0 to 237.9±12.2Bqkg−1 with a mean of 87.0±61.4Bqkg−1 and 300.1±5.5 to 1899.0±30.8Bqkg−1 with a mean of 1211.9±419.8Bqkg−1, respectively. Elemental concentrations were determined for U (from 1.0 to 20.7ppm with a mean of 7.2±5.3ppm), Th (from 3.0 to 58.6ppm with a mean of 21.4±15.1ppm) and K (from 1.0 to 6.1% with a mean of 3.9±1.3%). The radium equivalent activity (Raeq), the activity index, the emanation coefficient, the 222Rn mass exhalation rate, the indoor absorbed dose rate … |
