“…El-Dine et al (2001) report the range of values from 7-29 Bq m Ϫ2 d Ϫ1 . Hazal-ur-Rehman et al (2003) report an average flux of 32.4 Bq m Ϫ2 d Ϫ1 with a wide range of values. The equations given in this paper can be used for any other sealable accumulator and other integrating passive devices such as alpha track detectors.…”

An electret ion chamber (EIC) radon monitor in a sealed accumulator measures the integrated average radon concentration at the end of the accumulation duration. Theoretical equations have been derived to relate such radon concentrations (Bq m(-3) ) to the radon emanation rate (Bq d(-1)) from building materials enclosed in the accumulator. As an illustration, a 4-L sealable glass jar has been used as an accumulator to calculate the radon emanation rate from different granite samples. The radon emanation rate was converted into radon flux (Bq mm(-2) d(-1)) by dividing the emanation rate by surface area of the sample. Fluxes measured on typical, commercially available granites ranged from 20-30 Bq m(-2) d(-1). These results are similar to the results reported in the literature. The lower limit of detection for a 2-d measurement works out to be 7 Bq m(-2) d(-1). Equations derived can also be used for other sealable accumulators and other integrating detectors, such as alpha track detectors.

“…Usually, marble and granite have commercial names, petrographic and technological characterizations, and their producer countries identified. Numerous works [4][5][6][7][8][9][10][11][12][13] have quantified the 40 K, Unat , and 232 Th activity concentrations, in units of Bq/kg, in specific stones and other building materials.…”

Sixty samples of different marble and granite tiles used as building materials, from local and foreign origins, were collected from different factories in the Al-Madinah Al-Munawarah region of Saudi Arabia. Natural radioactivity of the U-Th series and 40 K in the samples were measured using an HPGE detector to conduct gamma-ray spectrometry. From the measured ␥-ray spectra, the activity concentrations for different marble samples of Turkish, Egyptian, and Omani origin were 232 Th (0.10 ± 0.07, 0.9 ± 0.09, 0.31 ± 0.06 Bq/kg), 226 Ra (5.7 ± 0.3, 7.3 ± 0.40, 2.0 ± 0.1 Bq/kg), and 40 K (0.9 ± 0.2, 0.96 ± 0.1, 0.8 ± 0.09 Bq/kg),
