| Abstract: | The calibration factor of 0.029 ± 0.0002 track cm?2 per Bq d m?3 for radon concentration measurements was determined using CR-39 and RAD7 detectors. The 222Rn concentration varied from 2,225 to 9,950 and 12 to 1,002 Bq m?3 in soil and water, respectively. The highest radon exhalation and gamma dose rates were found in Acid and undifferentiated granitic rocks and Miscellaneous soils. |
