    Opis:
    In this paper, the measurement of natural radioactivity in Sheep meat samples from different regions of Karbala governorate by using (Na(Tl)) detector. The results of measurements have shown that the specific activity and the determination of some other related parameters such as (Raeq , Hin, Iɣ, Iα, DƔ, Eff dos and AGDE). In fourteen four sheep meat samples by using NaI(Tl) detector. The results have shown that, the mean specific activity of (40K, 238U and 232Th) which were (6.813±1.82 Bq/kg, 3.865±1.033 Bq/kg and 1.02±1.03), respectively, were found to be less than the recommended values of specific activity given by (UNSCEAR, 2000).

    Opis:
    The reagent NaHMICdt•2H2O has found to be a good chelating agent for the spectrophotometric determination of various metal ions. The present investigation deals with spectrophotometric determination of Pd(II) by using NaHMICdt•2H2O. The reagent reacted with Pd(II) to give yellow complex extractable into toluene. Pd (II) was extracted quantitatively in the pH range 0.5-2.0. Pd(II)-HMICdt complex showed λmax at 435 nm. The extracted species has a 1:2 (M:L) stoicheometry. Beer’s law is obeyed in the range of 0.2-0.8 μg ml-1 of Pd (II). The molar absorptivity and the sandells sensitivity were found to be 0.754 x 104 lmol-1cm-1 and 0.0140 μg mol-1 cm-2 respectively. The effect of divers ion on the extraction of Pd(II) has been investigated. The proposed method is highly sensitive, selective, and simple and rapid has been applied for accurate determination of palladium in synthesis mixtures and real samples.

    Opis:
    This research focuses on the ground water quality index in Ado-Ekiti State, Nigeria. Groundwater sample wells were randomly collected and their spatial locations captured using a handheld GPS. Water samples were taken from 45 wells and their physio-chemical properties were analyzed in the laboratory. Spatial distribution maps of the water quality parameters were then developed. Herein, the Kriging method of interpolation from geospatial analyst wizard in Esri ArcGIS software was deployed in the generation of thematic maps of water quality parameters. A drinking water quality index was subsequently developed to describe the overall quality of groundwater in the study area. Laboratory analysis of 34 wells showed water of acceptable use as it conforms to WHO standard, while 11 wells were found to have unsuitable water for domestic use. The results further show spatial variation in the water quality. The south central depicts poor water quality, fair water quality in the south-east, while the North, north east, north-west down to the south west depicted the best water quality.
