“…This result is also in agreement with the work of Ogul et al, 32 where molybdenum is found to increase the radiation shielding ability of polyester‐molybdenum polymer composite at energies between 59 keV and 1332.5 keV. Abulyazied et al's 13 work on polyvinyl alcohol (PVA)—molybdenum composites also revealed the effect of molybdenum in radiation shielding, with the composite with the highest percentage of Molybdenum showing the highest shielding effectiveness, thus supporting the result obtained in this investigation. Furthermore, the LAC of DT1 is 27.5%, 26.6%, 25.3%, and 25.2% higher than that of DT2 at 29, 32, 34.8, and 37.8 keV, respectively.…”

“…The k-edge energy of molybdenum was responsible for the excellent absorption properties of the composites because it is close to the average energies of the x-rays considered in this work. This superior shielding performance of molybdenum oxide is also seen in similar works 9,11,13,21,31. DT1 has the highest MAC which ranges between 17.2% and 58.7% in comparison with DT2 and DT3 across all the energies considered in this work.…”

“…Molybdenum oxide has been used in many glass systems [9][10][11][12] for radiation shielding purposes and polymer composites. 4,13 Polymer composites are usually formed by different techniques some of which include melt-mixing, ion-implantation and electro spinning. 14 Previous works have shown the suitability of molybdenum oxide for radiation shielding applications, for example, Atta et al, investigated styrene-butadiene rubber (SBR-1502), iron oxide (Fe 2 O 3 ), zinc oxide (ZnO), molybdenum oxide (MoO 3 ) and titanium dioxide (TiO 2 ) composites for their effectiveness against gamma radiation.…”

Radiation protection is crucial in the protection of humans from the harmful effects of ionizing radiation. One of the most reliable ways of reducing the risk of occupationally exposed workers and the public in dental radiology is the installation of an effective radiation shielding barrier at the facility. Concrete barriers are predominantly used for dental shielding, however there is need to consider the use of lighter, ready‐made, and lower half value layer (HVL) materials as shielding materials in dental radiology facilities. In this work, low‐density polyethylene‐molybdenum oxide polymer composites were prepared (85C2H4‐15MoO3, 90C2H4‐10MoO3, and 95C2H4‐5MoO3), and the radiation attenuation measurements were carried out experimentally. The composites displayed acceptable x‐ray absorbing capabilities. 85C2H4‐15MoO3 polymer composite (DT1) showed optimal shielding in comparison with concrete. DT1 has an approximate HVL like concrete while it is 54.3% lighter than concrete. 85C2H4‐15MoO3 polymer composite is 1.5%, 0.8%, and 6.3% higher in linear attenuation coefficient than concrete at 60, 70, and 80 kVps, respectively. This implies that DT1 can effectively replace concrete at dental diagnostic energies.
