Assessment of natural and anthropogenic radioactivity levels in rocks and soils in the environments of Juban town in Yemen

Terrace soils in the Yemen Highlands: Using physical, chemical and radiometric data to assess their suitability for agriculture and their vulnerability to degradation

“…The paper of Abd El-Mageed et al (2011) provides very informative activity levels of NOR and 137 Cs in Yemeni top soils (0-2 cm, n = 16) in the area of Juban town, although developed on sandstone substratum. The average radioactivity concentrations of 40 K, 226 Ra and 232 Th in the 16 top soils analysed are 822, 44, 58 Bq kg − 1 , respectively, and the 137 Cs mass activity content ranges from 4.8 to 23.2 Bq kg − 1 (Abd El-Mageed et al, 2011). The mean activity NOR's concentration in our study is lower than these values.…”

Assessment of radiation hazards a result of natural radioactivity in water from Abyan delta, Yemen

“…Except samples (W3, W4 and W15), the concentrations of radionuclides Ra, 232 Th and 40 K in water samples under study were found in the narrow range. This probably is due to the fact that the sites studied cover an area with similar aquifer lithologies [14]. The abundance of 40 K activity observed in the water samples may be due to agricultural activities going on in the area that involve the use of potassium fertilizers which may have been transported to the groundwater, given that 40 K is a highly soluble element.…”

“…The catchment area contains intrusive rocks include granites and gabbros, some of these rocks like as granite and calc-silicate involve high radioactivity of 238 U, 232 Th and 40 K, scientific references for this measurements are noted in [14][15][16] for Juban and Assalamia-Alhomira area.…”

Investigation of Natural Radioactivity Levels and Evaluation of Radiation Hazards in Residential-Area Soil Near a Ras Tanura Refinery, Saudi Arbia

“…The activity concentration measured in this study was compared with those from local and other countries (Table 3) [7,26,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. The values of 226 Ra activity concentration in our study are lower than the values in similar studies in Yemen, Hungary, Yunnan, China, Turkey, Thailand, Algeria, Egypt, Pakistan, Iraq, and Jordan, while it is little higher than that of Sudan, Nigeria, and Malaysia, and within the range of India.…”
