This work present the Uranium (238U) content in soil samples collected in Ajaokuta from some villages was been determined. The measurement of the soil Uranium activity concentration were made using a multi–channel pulse height analyzer (Camberra series 10 plus) coupled to a 76.2mm x 76.2mm NaI (TI) scintillation detector. 2.93)The mean Uranium content in the analyzed samples was found to be (44.26 Bq/kg which is higher than the world mean value of 35Bq/kg. The results were in good agreement with others for soils from region which is considered as normal or slightly high in radioactivity level.
The effective atomic number, electron density and mass attenuation coefficient of some selected active pharmaceutical ingredients such as Diclofenac Sodium, Femotidine, Alprazolam, Amiodar, Amiodarone, Ciprofloxacin, and Nimesulide have been calculated over the energy range from 1 keV to 100 GeV for total and partial photon interactions by using WinXCom. The obtained data shows that the change in mass attenuation coefficient and electron density varies with energy and chemical composition of the active pharmaceutical ingredients (API’s) in drugs. The results in the variation of photon interaction with energy and effective atomic number of the API’s in drug are shown in the logarithmic graphs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
