“…These electrons are contributed by the chemical elements that made up the material. The value of Z eff is strongly dependent on the photon energy and the nature (atomic number) of the elements that make up the composite medium [22]. It is sometimes used to predict the nature and magnitude of photon interaction that leads to absorption in a given medium.…”

“…Progress in science and technology has continue to advance the sophistication in existing applications and discover new areas of potential application for these radiations [15][16][17][18]. These have demanded that new materials be researched and provided to satisfy the radiation shielding required in these emerging and existing radiation applications [19][20][21][22][23][24]. Today, many traditional shielding materials such as lead, concrete, depleted uranium, and many more are used for radiation shielding purposes.…”

“…Today, many traditional shielding materials such as lead, concrete, depleted uranium, and many more are used for radiation shielding purposes. However, they do not provide adequate shielding requirement in new and emerging technology involving the use of radiation applications [21][22][23][24][25][26]. This is due to the sophistication in properties that is required in today's shielding material coupled with environmental concerns.…”

“…This has made bismuth (Bi)-based glasses an alternative choice for radiation shielding due to its high density just like lead it possess good photon shielding efficiency. A glass system containing a combination of Pb and Bi will in no doubt be much more effective for radiation shielding purposes [22,25]. In order to satisfy the toxicity concern of users, Pb content of such glasses should be lower compared to the Bi content.…”

Kinetic, mechanical properties of xPbO-(10-x)Er 2 O 3 -90Bi 2 O 3 : x = 3 (BEP-3), 5 (BEP-5), 7 (BEP-7), 9 (BEP-9), and 10 (BEP-10) mol% glass system were investigated experimentally utilizing the pulse-echo technique and theoretically via bond compression and Makishima and Mackenzie models. Radiation shielding capacity of the investigated BEP-glasses was also evaluated via Phy-X/PSD code. The longitudinal and shear ultrasonic wave velocities were increased with the increase in PbO content in BEPglasses. Values of the elastic moduli, longitudinal modulus, shear modulus, bulk modulus, and microhardness, for BEP-glasses were enhanced when the PbO content increased from 3 to 10 mol % content. There was good agreement between the obtained values of experimental and theoretical values of elastic moduli. The maximum mass attenuation coefficient

Summary The work which has been done on cement‐polymer composite based shielding materials was comprehensively described in the present article, the choice of the study presented here is based on the choice of the researches. The new Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane Plaster‐concrete composites mixed with different percentage soft lead oxide and arsenic oxide is used to research gamma‐ray shielding and thermal conductivity characteristics. The synthesis of new Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane copolymer was achieved by Atom Transfer Reaction and Condensation Polymerization methods. The characterization of Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane Plaster was made with the Nuclear Magnetic Resonance, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, Gel Permeation Chromatography, Thermogravimetric Analysis, Scanning Electron Microscope methods. The transmitted fluxes of gamma‐rays that were emitted from Eu152 source was detected by a High Purity Germanium (HPGe) detector system at Karadeniz Technical University‐Department of Physics in Trabzon and analyzed by a GammaVision (Version:6.07‐Ortec, Oak Ridge, TN) computer program. The composite phase change materials including 89, 87, 69, 67% Portland cement, 1% and 3% PU‐Plaster, 10% and 30% weight percent lead oxide and arsenic oxide was irradiated in the various gamma ray photon energy region (121.78, 344.28, 778.90, 964.08, 1085.87, 1112.07, and 1408.01 keV) for 3600 seconds. Then, linear attenuation coefficients, mass attenuation coefficients, half‐value layer, tenth value layer, mean free path, radiation protection efficiency, and gamma‐rays absorption of concrete‐the Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane copolymers specimens were experimentally investigated. Thermal properties and morphological analysis of the irradiated substances were explored handling differential scanning calorimetry, thermogravimetric analysis, and scanning electron microscope methods of the nano lead oxide and arsenic oxide including composite phase change material via gamma irradiation were submitted. Moreover, the effect of the Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane amount on the radiation attenuation of the composite material was investigated. Gamma attenuation experiments have been performed to specify lead equivalent values for the improved composite material. The composite equivalent thickness values from 0.5 to 0.6 cm sample thickness and 0.665 cm radius were obtained. Via crosschecking the acquired data from concrete samples with and without lead and arsenic, it was observed that, if the powder of lead oxide and arsenic oxide to cement ratio of 10% and 30% by weight is added in the concrete mixture, the concrete‐the Hyperbranched Poly Amino‐Ester‐block‐Poly Caprolactone‐Polyurathane composite can be used as a suitable shield against gamma rays. Also, mass attenuation coefficients were calculated as theoret...
