Evaluation of natural radioactivity in soil, sediment and water samples of Niger Delta (Biseni) flood plain lakes, Nigeria

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.…”

Measurement of some Radioactive Elements in Drinking Water in Arar City, Saudi Arabia

“…This may explain the reported values in these wells being slightly higher than those reported in reference [13]. The relatively high activity concentration observed in the well may be attributed to increased anthropogenic activities in that area (oil exploration activities and frequent oil spills into the environment).…”

“…The relatively high activity concentration observed in the well may be attributed to increased anthropogenic activities in that area (oil exploration activities and frequent oil spills into the environment). The abundance of 40 K activity observed in the wells may be due to heavy agricultural activities going on in the area that involve the use of potassium fertilizers which may have been transported to the uncultivated sampled spots through one or more pollution transport mechanisms, given that 40 K is a highly soluble element [13]. The level of 232 Th observed may be due to the geology of the area (including the presence of metamorphic rocks like shale).…”

Determination of Concentrations of Natural Radionuclides in Soils and Water in Non-cultivated Sites in Seberang Perai, Malaysia

“…Table 3 compresses the natural radioactivity levels for all sort of water acquired in some world regions and this study. For instance, the mean value of 226 Ra from Yemen is roughly lower than those values [20] and Northern Malaysian Peninsula [10], and lower than that from Nigeria and Sudan [21,22] …”
