Ahmed M. El-Khatib,Mahmoud I. Abbas,Mohamed. A. Elzaher,M. Anas,M. E. El Moniem,Mahmoud Montasar,Ebeid Ellithy,Mahmoud T. Alabsy +7 more
TL;DR: In this article , waste marble and iron slag as aggregates are used to create novel cement mortar compositions to study the aggregate's impact on the radiation attenuation capability of the mortar.
Full-Energy peak efficiency of an NaI(Tl) detector with coincidence summing correction showing the effect of the source-to-detector distance
Ahmed M. El-Khatib,Bohaysa A. Salem,Mohamed S. Badawi,Mona M. Gouda,Abouzeid A. Thabet,Mahmoud I. Abbas +5 more
TL;DR: In this paper, the γ-γ coincidence summing correction factor (CSCF) for a 3× 3″ NaI(Tl) γray detector has been calculated at different distances from the detector end cap.
Calculation of the full-energy peak efficiency of NaI(Tl) detector using the efficiency transfer method for large radioactive cylindrical sources
Ahmed M. El-Khatib,Mona M. Gouda,Mohamed S. Badawi,A. Hamzawy,Nancy. S. Hussien,Mahmoud I. Abbas +5 more
TL;DR: In this paper, a new theoretical approach is introduced to calculate the full-energy peak efficiency of cylindrical NaI(Tl) γ-ray detectors based on an analytical calculation of the photon average path lengths inside the source-to-detector system.
Assessment of γ-radiation shielding behavior of some mixed nature clays
Ahmed M. El-Khatib,Mahmoud I. Abbas,M.I. Sayyed,M. Khandaker,Mohamed Abd-Elzaher,Mona M. Khalil,Mohamed Elsafi,Mona M. Gouda +7 more
TL;DR: In this article , a new composite of two types of clays, based on bentonite clay, as a natural, plentiful, and low-cost matrix was used to obtain the linear attenuation coefficient (LAC) of the Genie 2000 software in the presence and absence of the clay sample.
Enhancing the Gamma-Radiation-Shielding Properties of Gypsum–Lime–Waste Marble Mortars by Incorporating Micro- and Nano-PbO Particles
TL;DR: In this paper , the gamma-radiation-shielding characteristics of novel gypsum-lime-waste marble-based mortars reinforced with micro-PbO and nano-pbO powders were investigated.
