Magnesium oxide (MgO) and Zinc (ZnO) nanoparticles (NPs) have been successfully synthesized by solid–solid reaction method. The structural properties of ZnO MgO NPs were studied using X-ray diffraction (XRD) scanning electron microscopy (SEM). XRD results indicated a formation pure NPs. mean diameter values the agglomerated particles around to be 70 50 nm for NPs, respectively SEM analysis. Further, wide-range nuclear radiation shielding investigation gamma-ray fast neutrons samples. FLUKA...
Highly efficient gamma shielding of BZBB glasses with various Bi2O3 concentrations in the xBi2O3-30B2O3-(65-x)ZnO-5BaO, (5 ≤ x 25 mol%) were evaluated for their radiation properties. The μm results have been via NISTXCOM database and simulated FLUKA code. simulation values by Monte Carlo code (FLUKA) shown to converge correlate XCOM values. Shielding properties like HVL, MFP, Zeff, EBF, EABF computed. observed that Zeff increase increasing Bi2O3. 47.09, 48.91, 50.73, 52.54 54.36 (cm2/g) are...
Abstract A comparative study has been conducted by using Monte Carlo FLUKA code and Microshieldsoftware programs to the radiation shielding properties of plastic waste mixed with nano copper oxide (CuO) phosphotungstic acid (PTA). The variousdiverse percentages new nanocomposite have prepared compression moulding technique, then they are characterized Fourier transfer infrared spectrophotometer (FT‐IR), thermal gravimetric analysis (TGA), X‐ray diffraction (XRD). established as a effective...
(Tl2O3)30-(Li2O)10-(B2O3)(60−y)-(Sm2O3)y glass system with various Sm2O3 additives (y = 0, 0.2, 0.4, 0.6) was studied in detail. The vibrational modes of the (Tl2O3)30-(Li2O)10-(B2O3)(60−y) network were active at three composition-related IR spectral peaks that differed from those mixed Samarium (III) oxide high wavenumber ranges. These samples show their permeability increased content increase. Additionally, electronic transition between localized states observed samples. MAC, HVL, and Zeff...
In the present study, nanocomposites with different ratios of NiO and Co3O4 (x = 0.3, 0.5, 0.7) have been prepared via microwave oven characterized using XRD. FLUKA code has used to estimate values mass attenuation coefficient (μm) for all samples. From measurement, we found that when thickness samples increases, gamma transmission decrease. Besides, μm increase as content from 0.3 0.7%. At selected photon energy, HVL, TVL, MFP decrease increasing concentrations. low energies (0.1–0.5 MeV),...

Energy and directional distribution of neutrons at the Beloyarsk NPP workplaces is a subject this study. Measurements H∗(10) rate neutron energy were taken 8 workplaces, which can be divided into three categories: work with spent or fresh nuclear fuel, radionuclide sources, rooms adjusted to reactors. The Hp(10) measurements performed only 6 out locations, due fact that long term placing an effective moderator in fuel storage facility forbidden. As result research direction fields locations...

Testing RAM ION in the field of photon radiation was performed. No difference between measured values H'(0.07,Ω), H'(3,Ω) and H*(10) both for 137Cs 241Am sources obtained. The uncertainties readings were range from -4% up to -10%. It means it does not have any statistical is measurement uncertainty. In case testing beta radiation, 'real' value H'(d,Ω) calculated with Varskin 6.1. Ambient directional dose equivalent at 15 workplaces, including reactor hall, room spent fuel pool other special...
If the neutron fields at personnel workplaces differ from in which individual dosimeters are verified, there is a possibility of additional errors assessment such dosimetric quantities as ambient dose equivalent, equivalent or effective dose. To take into account energy distribution radiation flux density and geometry irradiation workers, it necessary to study characteristics personnel. In order obtain conditionally true levels exposure nuclear facilities, studies angular were carried out...
