“…Figure 5 shows comparison of current results for 40 K in soil with results reported for different countries of the world. The average activity concentration of 40 K found in the present study was nearly similar to the world average (420 Bqkg −1 ) reported in (UNSCEAR 1988), and higher from the average values reported for Egypt (Higgy and Pimpl 1998), Taiwan (Wang et al 1997), Libya (Shenber 1997), Saudi Arabia (Al-Kahtani et al 2001), USA (UNSCEAR 2000), India (Singh et al 2005), and Syria (Al-Masri et al 2006). The 40 K values are smaller than Italy (Bellia et al 1997), China (UNSCEAR 2000, Serbia (Bikit et al 2005), and Brazil (Venturini and Nisti 1997) as shown in Fig.…”

The analysis of gamma emitters natural radionuclides, i.e., 226 Ra, 232 Th, and 40 K, has been carried out in soil, vegetation, vegetable, and water samples collected from some Northern area of Pakistan, using gamma-ray spectrometry. The γ-ray spectrometry was carried out using high-purity Germanium detector coupled with a computer-based high-resolution multi-channel analyzer. The activity concentrations in soil ranges from 24.7 to 78.5 Bq kg −1 , 21.7 to 75.3 Bqkg −1 , and 298.5 to 570.8 Bq kg −1 for 226 Ra, 232 Th, and 40 K with the mean value of 42.1, 43.3, 9.5, and 418.3 Bqkg −1 , respectively. In the present analysis, 40 K was the major radionuclide present in soil, vegetation, fruit, and vegetable samples. The concentration of 40 K in vegetation sample varied from 646.6 to 869.6 Bqkg −1 on dry weight basis. However, the concentration of 40 K in fruit and vegetable samples varied from 34.0 to 123.3 Bqkg −1 on fresh weight basis. In vegetation samples, along with 40 K, 226 Ra, and 232 Th were also present in small amount. The transfer factors of these radionuclides from soil to vegetation, fruit, and vegetable were also studied. The transfer factors were found in the order: 40 K> 232 Th≈ 226 Ra. The analysis of water samples showed activity concentrations values for all radionuclides below detection limit. The internal and external hazard indices were measured and found less than the safe limit of unity. The mean value of outdoor and indoor absorbed dose rate in air was found 64.61 and 77.54 nGyh −1 , respectively. The activity concentrations of radionuclides found in all samples during the current investigation were nominal. Therefore, they are not associated with any potential source of health hazard to the general public.

“…The studies on the fate and transport of thorium in the environment are more limited. However, recently the biogeochemistry of thorium has generated more interest to the environmental scientists (Higgy and Pimpl, 1998;Zararsiz et al, 1997;Morton et al, 2001;Sar and D'Souza, 2002;Morton et al, 2002).…”

This study was performed to determine the distributions of radionuclides (238U, 232Th and 40K naturally occurring in Khrami Late Variscan crystal massif and soils overlapping its adjacent territory built by Neogene and Quaternary lava using a gamma-ray spectrometry with an HPGe detector. By identification of artificial radionuclide 137Cs concentration revealed the character of radioactive contamination of the area under investigation. Based on the obtained results, the radiological parameters (outdoor absorbed gamma dose rate, annual effective dose; radium equivalent activity) were estimated to assess radiation hazards caused by use of industrial materials. The difference was established between concentrations of radionuclides having emerged at the expense of Late Variscan crystal substrate and recently erupted lavas. The results were compared with similar studies conducted in different countries and with data and recommendations published by international organizations (UNSCEAR, ICRP).
