“…The detectors were calibrated with a radium standard in the Turkish Atomic Energy Authority Çekmece Nuclear Research and Training Centre (TAEK‐CNAEM) and the calibration factor was found to be 0.054 Bqdm −3 track −1 cm 2 . 42 The correct radon activity concentration depends on a well-calibrated detector. Therefore, in the present study, the calibration factor was determined for the same geometry conditions as the studied samples.…”

In the present study, radon exhalation rates in terms of mass and area, as well as the effective radium concentration in soil samples collected simultaneously from different districts of southern Sakarya have been measured by Sealed Can technique using LR-115 type-II detectors. Mass and areal radon exhalation rates in soil samples vary from 35.76 ± 1.5 to 253.15 ± 3.8 mBqkg−1h−1 with an average value of 112.53 ± 2.7 mBqkg−1h−1 and 0.73 ± 0.2 to 5.18 ± 0.6 Bqm−2h−1 with an average value of 2.30 ± 0.6 Bqm−2h−1, respectively. The effective radium content was found to vary in the range 3.77 ± 0.5 to 26.69 ± 1.3 Bqkg−1 with an average value of 11.86 ± 0.9 Bqkg−1. The area exhalation rate was also used to calculate indoor radon concentration contributed by radon exhalation from soil, and to estimate annual effective dose equivalent. While the indoor radon concentration contributed by radon exhalation from soil varies from 2.93 ± 0.9 to 20.73 ± 2.3 Bqm−3 with an average value of 9.22 ± 1.5 Bqm−3, the estimated effective dose equivalent varies from 0.09 to 0.61 mSvy−1 with an average value of 0.27 mSvy−1.

“…Bedrocks, superficial deposits, and faults (fracturing) also affect radon flux. Faults increase radon flux, and the influence of superficial deposits depends on the physicochemical characteristics of the deposits [82,122,123]. The condition of the soil surface also significantly influences radon flux.…”

Overview of Radon Flux Characteristics, Measurements, Models and Its Potential Use for the Estimation of Radon Priority Areas

Radon flux measurements provide information about how much radon rises from the ground toward the atmosphere, thus, they could serve as good predictors of indoor radon concentrations. Although there are many different mapping methods with many different input data, radon flux data are generally missing and are not included for the delineation of radon priority areas (RPA). The aim of this literature review is to investigate to what extent radon flux was used, or could be used, for the delineation of RPAs. Numerous factors influencing radon flux were identified, but quantifying their contribution to radon flux measurement still remains a challenge. Different methods and measuring devices were used for the determination of radon flux, thus it is necessary to identify possible inconsistencies in order to harmonise different radon flux measurements. Due to the complexity of radon flux measurements, only two countries were identified to have performed national surveys on outdoor radon, which were of much smaller scale compared to those on indoor radon. A positive correlation between radon flux and radon quantities, such as radon in soil gas and indoor radon, indicates that radon flux could be used as an input parameter for the estimation of RPA. By reviewing radon flux models, it was concluded that up-to-date modelled radon flux maps have reached excellent spatial resolution and will be further improved, hence, they could serve as an input for the estimation and delineation of RPA.
