A comparative Study Between Fluka and Microshield Modeling Calculations to study the Radiation‐Shielding of Nanoparticles and Plastic Waste composites

Abstract

A comparative study has been conducted by using Monte Carlo FLUKA code and Microshieldsoftware programs to study the radiation shielding properties of plastic waste mixed with nano copper oxide (CuO) and phosphotungstic acid (PTA). The variousdiverse percentages of new nanocomposite have been prepared using the compression moulding technique, then they are characterized using Fourier transfer infrared spectrophotometer (FT-IR), thermal gravimetric analysis (TGA), X-ray diffraction (XRD). The new nanocomposite has been established as a effective shielding material towards gamma radiation due to the presence of dense materials, like nano copper oxide and phosphotungstic acid. The gamma radiation attenuation has been established by using the previously mentioned methods.The results have proved that the mass attenuation coefficients (μ m ) and effective atomic (Z eff ), and electron densities (N el ) of the samples increased with increasing the phosphotungstic acid (PTA) content while the half-value layer (HVL), the tenth value layer (TVL), and the mean free path (MFP) decreased as PTA increased. Experimental Work Chemicals and MaterialsAll the chemicals in this work have been used without any purification, sodium hydroxide NaOH (FW 40 g mol À 1 and assay > 99 %, BDH company, UK); Copper (II) acetate Cu(CH 3 COO) 2 (FW 181.63 g mol À 1 and assay > 98 %, Sigma-Aldrich Company, USA);

Gamma irradiation, thermal conductivity, and phase change tests of the cement‐hyperbranched poly amino‐ester‐block‐poly cabrolactone‐polyurathane plaster‐lead oxide and arsenic oxide composite for development of radiation shielding material

“…[95][96][97] Our calculated HVL values, when also taking into account other research results, provide convincing information regarding the shielding ability of our PCMs in reducing the photon count to half of the current situation in accordance with the thickness of the samples. [98][99][100] The obtained values indicate that the MFP of glasses increases with photon energy (Figure 21A) Furthermore; the MFP value is one of the important factors that clearly explain the gamma radiation reduction capabilities of the shielding materials used. The lower the MFP value, the better the shielding ability of the material.…”

Exploring the FTIR, Optical and Nuclear Radiation Shielding Properties of Samarium-Borate Glass: A Characterization through Experimental and Simulation Methods

“…Photon buildup is small for an SMG0.6 glass sample with maximum Z eq values. Between 7 MeV and 15 MeV, the EBF and EABF values of the examined samples increased more rapidly, owing to the dominance of pair production and its dependence on Z 2 [ 32 ]. Figure 15 and Figure 16 display substantially higher EBF and EABF values as penetration depth (1–40 MFP) increases.…”

Gamma Irradiation and the Radiation Shielding Characteristics: For the Lead Oxide Doped the Crosslinked Polystyrene-b-Polyethyleneglycol Block Copolymers and the Polystyrene-b-Polyethyleneglycol-Boron Nitride Nanocomposites

“…For these reasons, polymer composite-based materials have been the focus point of scientific interest and active multidisciplinary and industrial research groups because of their interesting properties and potential [ 20 , 21 , 22 ]. In addition, many explorers have remarkably conducted polymer composite-based radiation-absorbing substances [ 23 , 24 , 25 , 26 , 27 ]. The fact that polymers can be with ease manufactured in a coating style, characterized with an extruder, or shaped for textural parts is substantial supremacy for gamma-irradiation shielding enforcements of polymer-based compounds.…”
