Abstract |
|
|
| Muscovite, a naturally occurring potassium aluminum silicate mineral, is the most widely used mica type in various industries. In this study, the concentration of uranium, thorium, and potassium radioisotope in fifty muscovite samples collected from commercially operated mica quarries located in Turkey were determined using an energy dispersive X-ray fluorescence (EDXRF) spectrometer. The concentrations of uranium, thorium and potassium radioisotope varied from 0.8 to 4.7 mg/kg with an average of 1.2 mg/kg, 5.5 to 16.7 mg/kg with an average of 11.0 mg/kg g and 7.0 to 10.7 mg/kg with an average of 8.6 mg/kg, respectively. Also, the radiogenic heat generation caused by the emitted ionizing radiation from these natural radionuclides in muscovite samples was estimated. Radiogenic heat generation values of muscovite samples varied from 1.4 to 2.7 µW/m3 with an average value of 1.8 µW/m3.
