“…The activity concentrations in water samples were comparable to control samples and other uranium mineralization areas reported in the literatures [24]. The concentration of heavy metals in soil, sediments and water samples on Cr, Fe, Zn, Pb, Th and U were found to be higher than the control samples but not above the allowed limits [25].…”

In the United Republic of Tanzania (URT), all environmental issues related to the mining industry are regulated according to two principle Acts: The Mining Act and the Environmental Management Act, and their respective regulations. The current acts were enacted in 2010 and 2004 respectively. Mineral exploration (that includes all on-site activities performed before a mining project is declared feasible) projects in URT appears to be "unforgotten phenomena" in the two major legislative documents, when it comes to environmental considerations. This phenomenon is believed to be causing detrimental effects to the environment. This paper, therefore, analyzes the current environmental regulatory framework on mineral exploration projects in URT and discusses few examples in which mineral exploration projects have caused damage to the indigenous environment. Furthermore, this study reviews environmental regulatory frameworks from other few countries in comparison with existing environmental regulatory framework prevailing in URT.

“…Containers of the same size and geometry were used for reference materials to calibrate the system for measuring radioactivity. The samples and reference materials were stored and kept for a period of 1 month to attain secular radioactive equilibrium among 226 Ra,232 Th, and their respective short-lived decay products 226 Ra and its decay products in the uranium series and 228 Ra and its decay products in the thorium series (Kurnaz et al, 2007;Samad et al, 2012). Finally, each Marinelli container was analyzed using a HPGe detector.…”

Thirty-nine Arabian and Turkish coffee powder samples purchased from various markets in SaudiTh were found to be 2.57 to 10.63 Bq/kg and nondetectable to 8.01 Bq/kg for Arabian coffee and nondetectable to 10.09 Bq/kg and nondetectable to 9.75 Bq/kg for Turkish coffee, respectively. Based on these values, we estimated the potential radiological hazards to consumer health from coffee powder. We determined the radium equivalent, annual effective dose rate, and external and internal hazard for each element, and all were found to be below the limit recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation. However, absorbed dose rate values for some samples were higher than the permissible limit. In all samples, the 137 Cs concentration was below the detection limit. The average annual committed effective dose values reported in this study were far below the world average value of 0.30 mSv/yr for an individual. In addition, the limit for the threshold consumption rate was calculated. The statistical methods were applied to study the relationship between all the calculated natural radionuclides and their hazard parameters. Results indicated that the use of these types of coffee had no significant radiological health risks. This study may contribute data on coffee powder for formulating regulations related to radiological health care.

“…As shown in Figure 1, with the use of coring tool, the first surface soil sample was collected at the depth level between 0 -15 cm [6], whilst the second soil sample was drawn at a depth of 15-30 cm from the surface at the same location. This depth (0 -30 cm) was choosen as it is almost the same as the depth of plough line [5].…”
